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

Chemical engineers today face a major dilemma when it comes to deciding what should hold paramount‚ economic gain or moral statute? Many practicing engineers are faced with problems that result from the consequences of their engineering decisions. Engineers have to realize the importance of proper engineering decisions and how one should act when faced with a problem such as deciding what comes first safety or economic gain. When faced with such a problem‚ engineers often employ the risk-benefit

La Madres de la Plaza Mayo Argentina‚ the second largest and most populated country in South America‚ was discovered in 1516 by Juan Diaz de Solis. As a result‚ Argentina developed under Spanish colonial rule. Buenos Aires‚ the country’s capital was settled in 1580 and by 1600 the country already had a booming the cattle industry. Later‚ from 1806 to 1807‚ invading British forces were expelled from Argentina. In 1808 Napoleon conquered Spain and two years later Argentinians created their own government

Chemical Warfare Final Draft Do you think it’s right to use chemical toxins to harm or kill people who are defending‚ or fighting for their lives? I don’t and that is why I am aganist chemical warfare. There are other ways which can be used to defend your country without taking away the lives of many people in such a barbaric fashion. Chemical warfare takels many innocent lives even when they haven’t done anything wrong! Chemical warfare is a way of torturing people with nerve‚ blister‚ and choking

Introduction: The chemical industry has become one of the largest manufacturing industries in the world since the beginning of the 21st century (Murmann‚ 2003). They convert raw materials such as oil‚ natural gas‚ air‚ water‚ metals‚ and minerals into more than 70‚000 synthetic chemicals (United States Department of Commerce‚ n.d.). Heavy demands on chemicals allowed prosperity of materials goods and had brought convenience for many people. Now they can be found everywhere around world‚ and even

Observations of Chemical Changes Purpose: The purpose of this experiment is to observe chemical changes in common consumer products to determine if the chemicals are basic‚ acidic‚ or remain neutral when mixed with other chemicals. Procedure: In this experiment‚ various chemicals were mixed together‚ to determine a reaction. Using two drops from chemical 1 and two drops of chemical two‚ unless otherwise stated‚ then recording the type of physical reaction or color changes that occurred.

development has been the idea of chemical weapons‚ especially those in the form of weaponized gasses. These weapons‚ which are defined as an “ammunition or device‚ specifically designed to cause death or other harm through toxic properties of toxic chemicals.” have the potential to cause an unprecedented amount of harm if their proliferation is not regulated. The presence of these weapons throughout history is all too familiar to many of the world’s nations. Early chemical weapons‚ such as Chlorine and

AP* Chemistry CHEMICAL EQUILIBRIA: GENERAL CONCEPTS THE NATURE OF THE EQUILIBRIUM STATE: Equilibrium is the state where the rate of the forward reaction is equal to the rate of the reverse reaction. At these conditions‚ concentrations of all reactants and products remain constant with time once equilibrium has been established at constant temperature. (In stoichiometry‚ we dealt with equations that went to completion; often equilibrium equations are going to fall short of this goal.) Reactions are
