DATE PERFORMED: JULY 20‚ 2007 SPECTROPHOTOMETRIC DETERMINATION OF EQUILIBRIUM CONSTANT FOR A REACTION ABSTRACT UV-VIS spectrophotometry is one of the most widely-used methods for determining and identifying many inorganic species. During this experiment‚ this spectrophotometry was used to determine the equilibrium constant‚ Keq‚ of the Fe3+(aq)+SCN-(aq)↔ FeSCN2+(aq) reaction. By determining the amount of light absorbed‚ the concentration of the colored FeSCN2+ solution was also quantitatively

Restoring Balance LeChâtelier’s Principle and Equilibrium Introduction Chemical equilibrium is a true balancing act. What happens when the balance is disturbed? The purpose of this lab is to observe the effects of concentration and temperature on equilibrium and to visualize how balance can be restored based on LeChâtelier’s Principle. Background Not all chemical reactions proceed to completion‚ that is‚ to give 100% yield of products. In fact‚ most chemical reactions are reversible

The Equilibrium Constant of an Ester Hydrolysis Reaction Jesus Flores March 30th‚ 2015 Abstract: This experiment was conducted in order to discover the Kc‚ equilibrium constant‚ of a hydrolysis reaction of an unknown ester #2‚ unknown acid‚ and alcohol #2 products. The first week consisted of creating the reaction mixtures in bottles‚ next was preparing a NaOH solution while neutralizing with KHP. The final week consisted of titrating the bottles with the NaOH solution prepared previously

ADHD Diagnosis of Children As long as there have been youngsters there have been grownups trying to label them and place them into groups This has never been more evident than in the over diagnosis of attention deficit hyperactivity disorder‚ ADHD. The motives behind drugging children excessively are the key to understanding why the diagnosis is so prominent. This grouping is not done for the well-being of the kids‚ but rather so that programs and agendas of adults could be followed and the

Psalmist Tell me not‚ in mournful numbers‚ "Life is but an empty dream!" For the soul is dead that slumbers‚ And things are not what they seem. Life is real! Life is earnest!

eat‚ or hear. God is anything and everything‚ the great and mighty. We can argue the fact that there are unlimited amounts of “God’s” in the universe. For example‚ if God is everything and we have a paintbrush‚ that paintbrush is a God on it’s own. Or another example is that we are our own God‚ and there would be over six billion God’s in the world. If there is no actual one being guiding us‚ who will say which God has more power over the other? Or what is right or what is wrong? If that is the case

The Real CSI This video raised many legitimate concerns about forensic science and the use of forensic science. Credentialing‚ regulations that are not in place‚ mistakes made by “experts”‚ and lawmakers using their opinions as expert testimony are all real problems with the forensic science field. The practice of fingerprint comparison is not regulated fairly and clearly as it was seen the case with Brandon Mayfield. He was wrongly accused of terrorism in Madrid Spain because his fingerprints

Classical Unemployment Classical or real-wage unemployment occurs when real wages for a job are set above the market-clearing level‚ causing the number of job seekers to exceed the number of vacancies. Many economists have argued that unemployment increases the more the government intervenes into the economy to try to improve the conditions of those without jobs. For example‚ minimum wage laws raise the cost of laborers with few skills to above the market equilibrium‚ resulting in people who wish to
