Chemical Reactions Lab Report Introduction: Chemical reactions is a process that involves rearrangement of the molecular or ionic structure of a substance. There are different types of reaction such synthesis‚ decomposition‚ single replacement‚ double replacement‚ and combustion. Synthesis is where two or more reactants combine to create a product. For Decomposition‚ it is the opposite where a product breaks down into reactants. In Single Replacement‚ reactants switches an element with another element

Case: AMERICAN CHEMICAL CORPORATION 1. Executive Summary Dixon‚ an American specialty chemical producer‚ wants to buy Collinsville plant from American Chemical Corporation‚ another typical chemical company in 1979. Dixon wants to diversify its product line buy acquiring the aforesaid plant‚ which produces sodium-chlorate to supply to paper producers in Southeastern part of the US. This plant initially cost 12 mln. USD and additional 2‚25 mln. USD needed to buy laminate technology to increase efficiency

FUTURE OF CHEMICAL WARFARE INTRODUCTION Background 1. Chemical Warfare is a method of warfare in which toxic or incapacitating chemicals agents are used to further the goals of the combatants. The concept of Chemical Warfare is as old as warfare itself. Until the 20th century such warfare was primarily limited to starting fires‚ poisoning wells‚ distributing smallpox-infected articles‚ and using smoke to confuse the enemy. The most extensive and large-scale use of Chemical Weapons was witnessed

| 1. For Part 2: Single-Displacement Reactions: For each of the four single-displacement reactions‚ describe what happened in each well. If a chemical reaction occurred‚ write a balanced equation for it. Then using the A‚ B symbols‚ write a general equation for a single-displacement reaction. Here are the chemical formulas of the reactants for each reaction: • zinc – Zn copper sulfate – CuSO4 • aluminum – Al copper sulfate – CuSO4 • zinc

we can learn to observe physical properties of varying substances as well as to use chemical reactions to observe chemical observe the chemical properties of varying substances. In experiment #1‚ we were able to detect physical properties of the aluminum and copper sulfate simply by looking at the substances. We then combined the two substances to see if they would create a chemical reaction and test the chemical properties. After being combined‚ bubbles and gas were created and the color of the

effectiveness at mass annihilation. Two of those weapons include chemical and biological weapons. These weapons are constructed solely to kill mass populations in the quickest amount of time as possible. Their most startling aspect is the cruelty in which lives are extinguished and brutalized. However‚ these two weapons are latently different. The definition of a chemical weapon is a weapon that uses any amount of toxic properties or chemical substances and that is intended to kill as an act of war. Biological

CHEMICAL PARAMETERS OF FRESHWATERS Objectives At the end of this section‚ students should be able to 1. Distinguish between freshwaters and seawater in terms of ionic composition. 2. Describe the variation of ionic composition in natural freshwaters and other inland waters. 3. Explain the factors that contribute to such variation. 4. Describe Gibbs’ model that explains the major factors contributing to variation in chemical composition of inland waters. 5. Explain
