5 Steps for Balancing Chemical Equations

5 Steps for Balancing Chemical Equations Being able to balance chemical equations is a vital skill for chemistry. Heres a look at the steps involved in balancing equations, plus a worked example of how to balance an equation. Steps of Balancing a Chemical Equation Identify each element found in the equation. The number of atoms of each type of atom must be the same on each side of the equation once it has been balanced.What is the net charge on each side of the equation? The net charge must be the same on each side of the equation once it has been balanced.If possible, start with an element found in one compound on each side of the equation. Change the coefficients (the numbers in front of the compound or molecule) so that the number of atoms of the element is the same on each side of the equation. Remember, to balance an equation, you change the coefficients, not the subscripts in the formulas.Once you have balanced one element, do the same thing with another element. Proceed until all elements have been balanced. Its easiest to leave elements found in pure form for last.Check your work to make certain the charge on both sides of the equation is also balanced. Example of Balancing a Chemical Equation ? CH4 ? O2 → ? CO2 ? H2O Identify the elements in the equation: C, H, OIdentify the net charge: no net charge, which makes this one easy! H is found in CH4 and H2O, so its a good starting element.You have 4 H in CH4 yet only 2 H in H2O, so you need to double the coefficient of H2O to balance H.1 CH4 ? O2 → ? CO2 2 H2OLooking at carbon, you can see that CH4 and CO2 must have the same coefficient.1 CH4 ? O2 → 1 CO2 2 H2OFinally, determine the O coefficient. You can see you need to double the O2 coefficient in order to get 4 O seen on the product side of the reaction.1 CH4 2 O2 → 1 CO2 2 H2OCheck your work. Its standard to drop a coefficient of 1, so the final balanced equation would be written:CH4 2 O2 → CO2 2 H2O Take a quiz to see if you understand how to balance simple chemical equations. How to Balance a Chemical Equation for a Redox Reaction Once you understand how to balance an equation in terms of mass, youre ready to learn how to balance an equation for both mass and charge. Reduction/oxidation or redox reactions and acid-base reactions often involve charged species. Balancing for charge means you have the same net charge on both the reactant and product side of the equation. This isnt always zero! Heres an example of how to balance the reaction between potassium permanganate and iodide ion in aqueous sulfuric acid to form potassium iodide and manganese(II) sulfate. This is a typical acid reaction. First, write the unbalanced chemical equation:KMnO4  Ã‚  KI  Ã‚  H2SO4  Ã¢â€ â€™Ã‚  I2  Ã‚  MnSO4Write down the oxidation numbers for each type of atom on both sides of the equation:Left hand side: K 1; Mn 7; O -2; I 0; H 1; S 6Right hand side: I 0; Mn 2, S 6; O -2Find the atoms that experience a change in oxidation number:Mn: 7 → 2; I: 1 → 0Write a skeleton ionic equation that only covers the atoms that change oxidation number:MnO4- → Mn2I- → I2Balance all of the atoms besides the oxygen (O) and hydrogen (H) in the half-reactions:MnO4- → Mn22I- → I2Now add O and H2O as needed to balance oxygen:MnO4- → Mn2 4H2O2I- → I2Balance the hydrogen by adding H as needed:MnO4- 8H → Mn2 4H2O2I- → I2Now, balance charge by adding electrons as needed. In this example, the first half-reaction has a charge of 7 on the left and 2 on the right. Add 5 electrons to the left to balance the charge. The second half-re action has 2- on the left and 0 on the right. Add 2 electrons to the right.MnO4- 8H 5e- → Mn2 4H2O2I- → I2 2e- Multiply the two half-reactions by the number that yields the lowest common number of electrons in each half-reaction. For this example, the lowest multiple of 2 and 5 is 10, so multiply the first equation by 2 and the second equation by 5:2 x [MnO4- 8H 5e- → Mn2 4H2O]5 x [2I- → I2 2e-]Add together the two half-reactions and cancel out species that appear on each side of the equation:2MnO4- 10I- 16H → 2Mn2 5I2 8H2O Now, its a good idea to check your work by making sure the atoms and charge are balanced: Left hand side:  2 Mn; 8 O; 10 I; 16 HRight hand side:  2 Mn; 10 I; 16 H; 8 O Left hand side:  Ã¢Ë†â€™2  Ã¢â‚¬â€œÃ‚  10  16  Ã‚  4Right hand side:  4

Prostate Cancer essays

Prostate Cancer essays The prostate is a gland that is located just underneath the bladder. It surrounds the urethra through which a man urinates. The prostate gland is therefore vital to proper bladder control and urine flow-rate. The prostate is also essential for normal sexual function. It is the gland of ejaculation, supplying 95% of the seminal fluid and the power to push it through the urethra and out of the penis. The normal prostate in an adult man is about the size of a walnut. Its size often increases over time, however, particularly once a man gets beyond age 40. Because the urethra runs right through the middle of it, a growth spurt of the prostate will squeeze the urethra and begin to choke off the urinary flow. This can effect the ability to urinate and perform sexually. Prostate cancer occurs when some of the cells that make up the prostate gland escape from the normal controls on their growth and start to divide, grow and spread in an uncontolled manner. At first the growth of the cancer occurs very slowly and is usually limited within the prostate gland. Later on in the course of the illness, the prostate gland cells can spread around the body, particulary to the bones where they can paues pain and disability. Estimates show that the cancer may have been growing in some men for up to 10 yearsbefore it causes symptoms and is diagnosed. Some men develop symptoms whereas others do not. In those who that do, the following symptoms are commonly found: Need to urinate frequently, especially at night Sudden, incontrolable urges to urinate A burning sensation or pain when urinating Continuing pain in lower back, pelvis, or upper thighs There appears to be several forms of prostate cancer. Some men ...

Molecular Aspects of Conservation Genetics Essay - 1

Molecular Aspects of Conservation Genetics - Essay Example Scientific genetic approaches have made it easier to identify the cryptic species in particular taxa, and thereby have conservational significance. To achieve a positive result on conservation efforts, especially those linked to an individual species, an in-depth study of the taxonomy is mandatory (Mace 2004). However, since extracting taxonomical evidence based on morphological characteristics of birds has been a â€Å"taxonomic-headache† (Howell and Webb. 1995), a designed systematic molecular approach is a much better alternative. Neotropical parrots belonging to the genus Amazona have been treasured for their capability to mimic human sounds and their beautiful plumage. However, most Amazona species parrots are under threat of extinction except Amazona farinosa, also known as the Mealy Amazon which is prevalent in parts of both Central and South America. Wenner et al conducted a study to evaluate and validate the taxonomy of A.farinosa species complex by employing analytical methods such as complementary analysis and multiple genetic loci. DNA sequence data from mitochondrial and nuclear introns were extracted from sources like frozen tissues, bone and toe pad extraction and were used to understand and analyse the relationship between the five sub-species of A.farinosa. In the mtDNA data set, 110 sites were variable while about 96 of the sites were parsimony informative. Unique haplotypes were identified and joined to estimate the percentage of relation between the haplotypes. Three distinct haplotypes clust ers and a minimum of 11 mutational steps were recognised. Phylogenies constructed using maximum-likelihood (for both individual as well as concatenated gene regions) and Bayesian method showed the existence of two negatively monophyletic clades- Central American clade and South American clade. The genetic distance recovered between both

Historical Events - Research Paper Example The development and expansion story of education has just remained to be one of the expanding accesses with various differences arising at every dawn of collegiate growth in each new era. Higher educational institutions were largely supported by the educational philanthropists whenever reflected back in the 12th century during the time of medieval universities development (Riesman, 2001). The higher education system is perceived to have mainly originated in the United States whereby its development has been influenced by a series of events. The federal government became directly linked to the higher education during the time of the civil war. During this period, the southern congressmen who had a tendency of opposing the legislature were missing in the action. Most of the proposals and objectives were created under the Morril Act of 1862 that was in pursuit of the educational motion gearing programs. Among the programs proved to subdue the higher educational programs included: mechanical, agricultural, and military sciences encompassing the liberal arts. The state decided to attach some new programs like agricultural and engineering to historic colleges. This was aimed at boosting the political strength and expansion of the university definition scope and the curricula between 1887 and 1914. This Act of Morril was termed as the land grant-act due to the collective su pport gain exert on colleges to enhance development. The second Morril Act of 1890 considered to be the latest stimulated the expansion power of the federal engagement in the education development. This led to the funding of projects that related to land-grant campuses (Razzell, 2006). Basing on the Morril Act with the federal legislation furry, African –Americans were faced with great attention through the receivership of mixed results due to differences experienced in treatment. This act provided the policy of strictly funding the African-American

Leaving a Legacy of Hope Essay Example for Free

Leaving a Legacy of Hope Essay So many people when asked what it was that drew them to this field would tell me, â€Å"I go home every night feeling good about the work I do.† Though this is a genuine and relevant answer to the question, it is not mine. I have always said that it is the people that make this work so special. What makes the population of people that we work with so incredible is that they are not caught up with the everyday way of life that you and I are. It is that freedom from conventions which sets them apart. They are not as worried about the latest fads, trends or fashions. They are people shaped through the years of their lives, filled with experience and wonder that is hard to imagine, let alone understand. They are individual’s not so much worried about â€Å"What do you think about me?† as much as, Do you love me? Their character and convictions are steadfast, and though they may be hardened to change, their hearts remain soft and tenable. The following essay has been written for these people, with hopes that it would inspire even a single person to take an earnest look at Oregon’s current service models for Seniors and People with Disabilities, and to keep Oregon as a premier model in which other states can continue to look to. What legacy will we leave? What hope will we inspire? My objective is to utilize this essay to answer these questions. In our state’s history, Oregon has been blessed with so many great advocates and has been a National leader with the Self-Directed Support model of services across the division of Seniors and People with Disabilities. So how will the new generation of college graduates continue this legacy? After an in depth inquiry into this subject and much self reflection, I submit the following. As we begin to take those choice words like â€Å"Independence, integration, productivity, choice and dignity†, and not just make sure our companies or non-profits mission statements included a few of them, not just check off the box on the service plan that says these are being implemented or accomplished, but actually look at the root meaning of the words. Are we really where we want to be? Or can we do better? We have a choice, we can take a rational and intellectual inquiry into our current and proposed service models to see if the services we are providing and more importantly plan to provide fall in line with these words. Or, we can set our sights on mediocrity, from which no legacy will be made. The choice lies with us. Do we remain stagnant and content with the progress made? Do we measure Oregon against the backdrop of other states and take solace in the fact that we may still be slightly ahead of the pack? I think the answer among fellow Oregonian’s would be a resounding â€Å"No†. The preservation of Oregon’s existing legacy as being a National leader in the legislative, economic and social advocacy for seniors and people with disabilities is important. It is something that I conclude can only be done by my previous statement of rational and intellectual inquiry into Oregon’s current and proposed service models. My personal response to this inquiry is based around the philosophy of person centered planning and person directed supports. With the heart and focus of this model remaining on individual choice. At the age of 25 years old, having spent 5 years in human services I have worked within all different areas of Oregon Seniors and People with Disabilities. Through this time, one theme that I have heard loud and clear from the people I have supported is the need for choice, more specifically is choice as it pertains to the location in which people live while receiving services. Which leads me to the following; If Oregon is going to continue to be a leader and innovator in providing the Self-Directed Support model of services, the legacy of hope that we need to focus on leaving would stem from successful implementation of what is known as the â€Å"Community Based Care† models of services. The emphasis of this model being on serving seniors and people with disabilities in ways to help them live and age comfortably in the place of their choice. Rather than emphasizing their diagnoses, medical condition or inabilities, we focus on the things in life that give them happiness, peace and strength. All things that can be accomplished through something many of us now take for granted, and that’s having the freedom and choice of where we live. As the medical field progresses people are living longer and healthier lives than ever before. The number of those over the age of 65 is growing dramatically. There are 10,000 new Medicare recipients added each day. In 2000 the number of seniors over the age of 85 was 4.2 million. By 2010 the number is estimated to be 6.1 million. Beginning in the years 2011 2012, the baby boomers will begin to turn 65 years old. More astonishing then that, by 2030, Americans 55 and older will account for 31% of the population and those 65 and older will account for 20%. From the fiscal standpoint, Community Based Care has been projected to cost as little as a few hundred dollars a month, comparatively to someone who has been displaced from their home and is living in a facility where the monthly cost to the tax payers now shoots as high as $5,000- $6,000 monthly. The SPD population overwhelmingly wants to age in place, to be able to remain living in their own homes. But they very concerned about their choice to do so. In the book, â€Å"Water for Elephants† Sara Gruen, writes from the perspective of a man named Jacob Janokowski a retired veterinarian who is 90 years old, (or 93 he can’t remember which). Below is an excerpt from the book I believe helps illustrate the discussion. â€Å"But Dad, they said, you broke your hip, as though maybe I hadn’t noticed. I dug my heels in. I threatened to cut them off without a cent, until I remembered they already had controlled my money. They didn’t remind me- they just let me rail on like an old fool until I remembered of my own accord, and that made me even angrier because if they had any respect for me at all they would have at least made sure I had the facts straight. I felt like a toddler whose tantrum was being allowed to run its course. As the enormity of my helplessness dawned on me, my position began to slip. You’re right, I conceded. I guess I could use some help. I suppose having someone come in during the day wouldn’t be so bad, just to help out with the cooking and cleaning. No? Well how about a live in? I know I’ve let things slip a little since your mother died†¦ But I thought you said†¦ Okay, then one of you can move in with me†¦ But I don’t understand†¦ Well, Simon, your house is large. Surely I could†¦? It was not to be. I remember leaving my house for the last time, bundled up like a cat on the way to the vet. As the car pulled away, my eyes were so clouded by tears I couldn’t look back. It’s not a nursing home, they said. Its assisted living- progressive, you see. You’ll only have help with the things you need, and then when you get older†¦ They always trailed off there, as though that would prevent me from following the thought to its logical conclusion.† I truthfully believe it is a realistic belief that Oregon can pioneer the cause of helping seniors and people with disabilities live confidently with independence, and the freedom to age with a positive sense of self-worth in their own homes. This is my vision of Community Based Care, and this is the legacy that I hope to leave behind.

Criticism of Goldsmith’s, She Stoops to Conquer Essay -- She Stoops Co

Criticism of Goldsmith’s, She Stoops to Conquer In reading T.G.A. Nelson's critical essay "Stooping to Conquer in Goldsmith, Haywood and Wycherley" I have to say I that I was pretty scared. Drawing Freud to anything can really be scary according to almost anyone though, certainly in early criticism of "She Stoops to Conquer." As Bernard Harris says, "we should not discount unconscious forces in any comedy", but then he immediately drops the subject saying that "Goldsmith's main interest lies elsewhere."(325) The main focus of Nelson's essay seemed to be on the difficulty that certain men seemed to find "in achieving a satisfactory sexual relationship with a woman resembling the mother. "(319) This essay will look at what Nelson has to say about this Freudian ideology and bring to light my comments on the subject. Nelson begins by looking into some of Freud's essays and applying them to the characteristics describing the "Restoration rake. "(320) One example is how there is compulsive repetition in his relationships. Passionate attachments are formed again and again creating a long line of lovers. The preference for married women is also there, where another man claim the right of possession of her and yet the rake prefers her to one who is "disengaged. " Taking Goldsmith's play, Nelson uses it as the clearest example of Freud's theory. In his play, the character Marlow is very forthright in his dealings with those in a lower station, but with women of quality he becomes shy. Evidently, women of low social standing fail to qualify as 'modest women' for him and this fits closely into "Freud's description of the sufferer of selective impotence. "(322) Reading further it's found that the reason Marlow is so shy with those of hi... ... such an approach to a comedy traditionally, if tacitly, regarded as bland, inoffensive, and largely devoid of sexual content."(326) I applaud Nelson for the work and research he put into his essay; and I'm not saying that just because a play is a comedy, it can't have underlying feelings of repression or other factors involved in its creation. It's just on general principal then, having read Goldsmith's play and enjoyed it for itself while noting possibilities for his commenting on social/class order or the differences between city and country life, that I set aside Nelson's criticism of the play and leave it as it stands, untouched by Freudian ideology.

Current Health Care Issues

Current Health Care Issues HCS/545 Camille Fuller University of Phoenix The health care industry exist to provide preventative measures, diagnose health conditions, repair, and provide services to improve the quality of life. The cost of health care continues to rise each year. Health care fraud is a factor that continues to plague the health care industry. The affect health care fraud has on hospitals, is the increasing cost of medical services. The following research will examine and evaluate how organizational structure and governance, culture and the lack of focus on social responsibility affects on health care fraud. The following research will also include recommendations for prevention of health care fraud, recommendations for change of structure, governance, and culture. The following research will include prevention measure for future situations involving health care fraud. Health care fraud is a preventable situation in hospitals across the nation. Hospitals spend thousands of dollars on quality assurance and patient safety and still health care fraud continues to occur. Individuals across the nation make a living through health care fraud. Honest, hard working citizens of this country are financing health care fraud recipients, not by choice. Insurance companies, Medicare, and Medicaid are being schemed by fraudulent businesses. Channel 11 news in Colorado a scheme called, â€Å"Medical Provider Identity Theft† has been uncovered. Perpetrators stol the identity of a physician in Pueblo, Colorado. The perpetrators set up an office in Denver, Colorado called, â€Å"A Plus Billing. † The office and address was used to receive mail and phone calls. The physician’s name and medical identification number was used to bill Medicare for test and procedures that were not preformed. This type of scheme is running rampant across the United States. Dr. Cabiling did not know that his identity had been stolen until he received a phone call from Medicare. Medicare asked Dr. Cabiling if he practiced in Denver and Dr. Cabiling said, â€Å"No. † Medicare then notified Dr. Cabililng that they had received bills from an office in Denver with his name and medical identification number for payment of services rendered. Dr. Cabiling only practices in Pueblo and not in Denver. Further investigation uncovered more than $1. 8 million dollars had been paid out to the A Plus Billing Company. â€Å"Court documents show the address A Plus Billing used was 600 17th Street in Denver, room 2800. The company submitted bills for numerous things including MRI’s and EKG testing, claiming they had medical offices at that address. But instead, 11 News discovered it was home to a company hired to receive mail and answer the phone for $150 a month. And, according to records, the lady who was suppose to pay that bill, Aliya Valeeva, is no longer in the country. Medicare sent the money to an account at a BBVA/Compass Bank in Denver, under the name of A Plus Billing. Now the FBI has moved to seize nearly $800,000 of it (Potter, 2011). † Dr. Cabiling inadvertently received checks from Cigna, leading the physician to believe that the ghost company had targeted other insurance companies other than Medicare. Prior to President Obama’s health care reform, insurance companies were required to submit payment for services rendered within 15 days of receipt of the claim. Since President Obama's health care reform act the timeline for payment of services rendered gives agencies more time to make payments, review and investigate claims. Fraudulent claims are easier to detect with the new health care reform in affect. Fraudulent claims are nothing new to insurance companies. Perpetrators have targeted insurance companies for a long time. Medicare and Medicaid are the two type of insurance companies targeted. Medicare and Medicaid staff is inundated with claims. There are more claims to be processed then there are staff and time. New timelines and guidances to follow, allow the staff to follow up on suspicious claims. Since the Affordable Health Care Act was passed and implemented â€Å"Medicare officials say with their new tools for fighting fraud, they have reclaimed $4 billion last year alone (Potter, 2011)†. The previous organizational structure for payment of services rendered did not allow officials enough time to investigate claims to ensure the claims were legitimate. Perpetrators study the law and use the knowledge to fraud insurance and government agencies. The governance of rules, regulations and laws was not stringent enough to stop perpetrators from frauding the system. New guidelines allow agencies more time to detect suspicious claims, investigate and save the insurance companies millions of dollars. Society does not concentrate on proactive actions to prevent fraud, instead society deals with the problem after the fact. Consumer watch groups do not have tools in place to prevent fraud. Perpetrators rely on the oversites of insurance companies in order to target and fraud insurance companies. Insurance companies and the federal government should pool resources using a percentage of profits to finance a task force to arrestively fight fraud. The penalty for fraud should be more stringent which will cause perpetrators to think twice before formulating a plan to commit fraud. The Affordable Health Care Act is the beginning of many programs established to fight against fraud. Health care fraud is a growing problem and should be taken more seriously by citizens of the United States. Physicians, health care workers, and patients are responsible for proactively protecting personal information to prevent identity theft. The case of Dr. Cabiling could not have occured if his medical identity had not been stolen. A closer watch of personal information to prevent identity theft is the beginning to prevent health care fraud. The federal government should have in place the ability to prosecute offenders to the fullest extent. Harsh punishment may deter offenders from comiting the offence. Ethical issues concerning medical fraud is as simple as knowing what is right and what is wrong. Society should take responsibility of his or her own personal information. Identity theft is no secret, therefore society should be more proactive. Do not leave an open door for offenders to walk in and take what does not belong them. The laws for offenders should be more stringent. The current structure of physicans medical information is too easy to obtain. The structure of physicains medical information should be in encripted messages making the degree of difficulty high enough to ward off offenders. There are some offenders that will stop at nothing until they have gotten the information he or she is wishes to obtain. Stricter rules and guidelines can ward off these offenders. Governance over the guidelines for payment for services rendered should include the following; varification of physician’s medical information making sure the physican is aware of the charges being submitted to insurance companies. The time line for payments to be released to physicians or billing companies are lenghtened to allow incurance companies time to investigate suspecious claims. The culture of one waiting for another to do what is right is an occurance needing change. The culture can be changed through leading by example. Educating society through public service announcement is a start. Public service announcements reach more people than emails, newspaper articles, and phoone calls. An aggressive campaign to stamp out medical fraud through prosecuting identity theft offenders is an additional way to combat medical fraud. Through public service announcements society is informed of his or her responsibility to protect personal information to prevent identity theft and medical fraud. Fighting identiy theft and medical fraud cost less than the billions of dollars paid out to offenders. Remind society they the communities in which he or she live in are the one that ultimately pay the price through higher health care premiums, higher prices for health care services, and through higher taxes. In conclusion health care fraud is now being done through identity theft. Identity theft can be combatted through public awareness and the public taking responsibility to protect his or her own persoanl information. Dr. Cabiling through no fault of his own was a victim of identity theft. Dr. Cabiling did not know that his medical identity had been stolen until he received a phone call from Medicare. Dr. Cabiling can now contact the different insurance companies to alert them of the fraudulant activities concerning his medical information. The insurance companies can contact Dr. Cabiling prior to making payments on calims. The insurance companies making phone calls to Dr. Cabiling may take more time, but will save the companies money in the long run. Combatting medical fraud and identity theft is everyone’s responsibility. References Cohen, G. (2010, March/April). Medical tourism: The view from ten thousand feet.
