Purpose: To Inform Topic: Chemical Warfare Intro 1) Chemical weapons are extremely toxic chemicals which differ from explosive weaponry. Middle ages and renaissance are documented to have used poisonous chemicals on individuals. Chemical warfare is use of chemical agents to kill or incapacitate the enemy. 2) Today I will inform you of different chemical agents. Since World War I‚ several types of agents have been developed into weapons. These chemical weapons include (I) Choking

Harmful Chemicals in our Environment Over the past century humans have introduced a large number of chemical substances into the environment. Some are the waste from industrial and agricultural processes. Some have been designed as structural materials and others have been designed to perform various functions such as healing the sick or killing pests and weeds. Obviously some chemicals are useful but many are toxic and their harm to the environment and our health far outweighs their benefit to

* Chemical Formulas and Reactions . . . Midterm Objectives: * To balance chemical equations. * To interpret chemical reactions. * To understand equilibrium reactions and the factors that can affect them. * Molecular Mass / Formula Mass * Is the sum of the atomic masses of all the atoms present in one molecule of that compound. Example: the molecular mass of sodium bromide‚ NaBr‚ is 103‚ which represents the sum of the atomic mass of sodium (23) plus that of bromide (80)

ESSAY: WHY I WANT TO BE A PROFESSIONAL ENGINEER Amy McLeod “Engineering is not merely knowing and being knowledgeable‚ like a walking encyclopaedia; engineering is not merely analysis; engineering is not merely the possession of the capacity to get elegant solutions to non-existent engineering problems; engineering is practicing the art of the organised forcing of technological change… Engineers operate at the interface of science and society.” - Dean Gordon Brown.
