Introduction: Chemical equilibrium is when the concentrations of the reactants and products have reached a state where reactions occurring in one direction are at the same rate of reactions occurring in the opposite direction. This process‚ called dynamic equilibrium‚ is the main subject of Le Chatelier’s Principle. Le Chatelier pointed out that if a system at equilibrium is subjected to a stress that momentarily causes the system to be not in equilibrium‚ a spontaneous change will occur to

Energy‚ often in the state of heat‚ is involved in chemical reactions and phases changes. Changes in energy‚ can translate in temperature differentiations. In such a case‚ energy is transferred as heat. The quantity of heat exerted in a reaction referred to as (joules) can be identified through the following equation: Heat Exerted= (Mass of Sample) x (Specific Heat) x (Change in Temperature) q=msΔT Within a calorimeter is where the reactions within this lab take place. A calorimeter allows the

Thomas Newberg Chemical Weapons Convention Historically chemical weapons are rarely seen in combat but when they are they are used to great effect‚ killing thousands and injuring many more. Chemical weapons were first used in combat in May 1915 when the Germans released chlorine gas against the French in the Battle of Ypres. Over the course of WWI new chemical agents were developed including cyanide‚ phosgene and mustard gas. The Geneva Protocol of 1925 condemned chemical weapons but states that

Lorenz Anthony D. Cortezo 11285885 QM in Action Last year‚ Bank of the Philippine Islands (BPI) and Philippine National Bank (PNB) was in the talks for a merger of both companies. This merger will make the biggest bank in the country combining the assets of the two to a sum of 33 Billion USD. The deal didn’t transpire though because as of the December 15 deadline‚ no talks were settled. This made Banco de Oro (BDO) the biggest bank as of late. What interests me is what will happen if the

you direct equality quit like Affirmative Action does. If you consider affirmative action for its intentional purposes than Affirmative Action is very just‚ its purpose being to equalize the education and economic gap between minorities and causations. Although it is not a perfect method to achieving equality in this country‚ it is essential to accept it for why it’s been put into place and that it is all part of a process. Of course affirmative action

2013 Title: Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and to associate chemical properties with household products. Procedure: In this experiment I used a 96-well plate to hold each of the chemical reactions that occurred during this lab. Using a pipet‚ I added two drops of one chemical with two drops of another chemical and observed the effects of each reaction. Data Table 1: Experimental Data Well # | Chemicals | Observations | |

Experiment #17 Classification of Chemical Substances Prepared for: Dr. Robert O’Reilly By: Kudaibergenov Baizak 20.11.2013 Nazarbayev University Introduction While many thousands of substances are known‚ they can be classified into a few simple categories based on type of bonding that exists among the atoms in the substance. Bonds are chemical forces that hold atoms together to form molecules or compounds. These categories are ionic‚ molecular and metallic substances.

21st‚ 2013 MC 205 Week 4 Instructor Rein Chemical Stress Testing A chemical stress test is used when a traditional stress test (called a cardiac stress test) cannot be done. A cardiac stress test requires you to walk on a treadmill or ride a stationary bicycle until your heart rate reaches a level where your heart is “stressed”. You may not be able to participate in this kind of test if you have a condition such as a stroke. In this case‚ a chemical stress test is used. This test is used to help
