Juliana Amenta 2/18/13 Mr. Zastrow Chemical Warfare During World War 1 The first World War has been reported to be one of the most brutal wars in the history of time for many reasons. One of those reasons was strategic usage of chemical warfare. Chemical gas was used on both sides of the line‚ which turned out to be fatal for many. World War I was mostly fought in the trenches‚ where soldiers lived in deep‚ v-shaped holes or underground bunkers. Both sides would occupy these trenches in order

There are many different ingredients in a kitchen that causes a chemical reaction with baking soda. This experiment was designed to test 4 kitchen ingredients(Omega oil‚ water‚ lemon juice‚ and vinegar) mixed with baking soda‚ to see which one will cause a balloon to expand. It was hypothesized that baking soda mixed with lemon juice and vinegar would cause the balloon to expand. Using these ideals the experiment was completed and the data was recorded. It was decided that the hypothesis was correct

Physical and Chemical Reactions Lab #4 Alesa Cannon Objective: To investigate the physical and chemical properties of a pure chemical substance. Procedure: 1. Half-fill one well of a 24-well plate with 6 M HCl and half-fill a second well of the 24-well plate with 6 M NaOH. Suck up these chemicals into their labeled pipets for later use. 2. Perform the following steps on each of the substances to be tested. Complete all tests of one substance and record your observations before proceeding

Lesson #1 Potential Energy Diagrams Aim: How can the process of a chemical reaction be illustrated? I. Potential Energy Diagrams = relationship between activation energy and heat of reaction for a chemical reaction 1. Activated Complex = temporary composite of atoms or molecules that will eventually form the products of the rxn. = highest point on diagram is potential energy of this composite

Chemical reactions proceeding until all the reactants are used is a common misconception. Chemical reactions actually behave differently. The general reaction equation is a A + b B → c C +d D in this equation A and B are the reactants forming the products C and D. However‚ unlike the common thought that the reaction ends when it runs out of A and B it actually does not. In most reactions C and D start to react to form A and B at a certain point as you can see in the equation c C + d D → a A + b

Shanel Warren Tiffany‚ Princess‚ and Wei October 2‚ 2013 Determining the Mole Ratios in a Chemical Reaction Introduction The purpose of this lab was to determine the mole ratios of the reactants hypochlorite ion (OCI ) and thiosulfate (S O ) when reacted in a chemical reaction. A chemical equation gives the mole ratios of the reactants and products involved in the chemical reaction. When some formulas of the products are not known‚ experimental measurements can be made to determine

World War I Chemical Warfare On April the 22‚ 1915 at the start of the Second Battle of the Ypres‚ the first poison gas attack and the first use of chlorine gas in a battlefield started‚ even though the Hague declaration and Convention forbade the use of poison weapons in the warfare. The Germans attacked France with the chlorine gas‚ but the French were not prepared at all for this attack. The effects of the chlorine gas to the soldiers was very severe; within seconds it destroyed their respiratory
