The threat of chemical weapon attack is very real; either in conventional warfare or by a lone wolf terrorist group. This fact is buttress by the facts in the reading assignments, continue efforts by some government to acquire chemical weapon technology, and open declaration by some terrorist groups of their intention to use it if they can lay their hand on it. According to Ramesh et al (2010), chemical attack usually result in a chaotic situation with victims in various level of painful distress

ntroduction Why did the United States introduce chemical weapons and defoliant agents into the Vietnam War? The United States Military introduced chemical weaponry in their attempts to defeat communist forces in Vietnam. Because of the nature of the terrain, which consisted mostly of dense jungle, the US Armed Forces were unable to effectively target their enemy, the Vietcong. The introduction of chemical weapons, notably defoliant agents such as Agent Orange, enabled the US military to clear large

A Simple Chemical Reaction with Beautiful Colors. Introduction In this lab we are going to be working on chemistry and a chemical reaction. A chemical reaction is when two or more chemical meet each other causing a change or reaction to the chemicals being mixed. We are going to do a chemical reaction ourselves, we are going to Represent this chemical reaction with milk, food coloring and dish soap. When you see this chemical reaction known as a non-polar molecule, although this is not an explosion

There’s a difference between a chemical and physical prop-erties/changes. Physical properties are an aspect of matter that can be observed or measured without changing it. The Examples for Physical properties would include: color, smell, freezing point, boiling point, melting point, etc. While Chemical properies may only be observed by changing the chemical identity of a substance. An example for Chemical properties would be rusting iron. Physical change rearranges molecules but doesn't affect their

Topic/Central Focus: Students will observe and identify what a chemical change in matter is. Students will do this through an experiment and discuss chemical changes as well. It is important for students to recognize and understand what a chemical change in matter is and how it can apply in their lives, such as cooking or cleaning. Prior Student Knowledge: The class is composed of 12 students, with 8 girls and 2 boys. Most of my students are of Hispanic descent. Most of these students speak

am particularly interested in applying Chemical Engineering because I have always been inspired by those who are working offshore in the petrochemical industry. Since I was a child, I have always loved doing backyard experiments myself and observing the reaction that occurs. To me, Chemical Engineering is the most intriguing branch of engineering because it involves how to make the world a better place for us to live in through scientific mediums. Chemical Engineering will allow me to explore what

Fundamental of Science (Assignment 1) Measuring Quantities for Chemical Reactions P1 1. The atom is mainly made up of two specific regions : the positively charged nucleus made up of protons and neutrons, and the shells (orbitals) in which electrons are present, were they orbit around the positively charged nucleus to create a neutral atom. The Atoms are thus made up of three subatomic particles: The proton, neutrons and electrons. The protons are positively charged while the electrons are negatively

Chemical Reactions Chemical reactions are the heart of chemistry. People have always known that they exist. The Ancient Greeks were the firsts to speculate on the composition of matter. They thought that it was possible that individual particles made up matter. Later, in the Seventeenth Century, a German chemist named Georg Ernst Stahl was the first to postulate on chemical reaction, specifically, combustion. He said that a substance called phlogiston escaped into the air from all substances

everyday life, we witness many chemical reactions. Some fun reactions you may know about are mentos and pop or vinegar and baking soda. Those two reactions are visible to the naked eye. You aren't able to see photosynthesis completely but you know that it take place because a plant grows. Now what about the chemical reactions that you aren't able to see? How do you know when they are complete? Well let me explain this bright and interesting new discovery. Most chemical reactions develop to be transparent

Department of Chemistry Observations of Chemical Changes Submitted by Date Submitted: 5/30/2012 Date Performed: 5/30/2012 Lab Section: Chem-181DL1 Course Instructor: Purpose The purpose of the experiment Observation of Chemical Changes is to examine the properties of chemical reaction and relate those reactions to products commonly found in a home environment. Through this experiment someone can macroscopically analyze whether a solution
