Biological and Chemical Outline Biological and chemical warfare has been around since the beginning of time. From poison tipped arrows to purposely transmitting smallpox to individuals. There has been ongoing political conflict on biological and chemical warfare for quite some time for legitimate reasons too. Biological and chemical warfare is very deadly and sometimes inhumane‚ but on the other hand it is very cost efficient and is very effective at doing its job. Biological and chemical warfare

Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance

2014 Lab report #1 on chemical and physical properties/ changes Introduction Summary: The purpose of this experiment is to allow students to understand how to differentiate physical and chemical properties and reactions of matter by observing changes of matters under circumstances. Physical properties are properties of matter that can be observed without changing the composition of the matter‚ including the volume‚ mass‚ color‚ density‚ and shape of it. Chemical properties include the matter’s

Overview Chemical Warfare is using the chemical properties of a substance to your advantage during war. This has been going on for centuries. Even the most basic forms of weapons were used. People have been putting poison on the end of their spears and arrows since they have been around. Over the years‚ it has also developed into much more advanced chemistry. In this article‚ I am going to focus on the more advanced‚ modern uses of chemical warfare in World War I and World War II. World War

Name: Tom Flannigan Title: Physical and Chemical Properties Purpose: To investigate the chemical properties of pure chemical substances. To investigate the physical properties of pure chemical substances. Procedure: For this lab we used four test tubes and poured equal amounts of a substance in each test tube. We then observed the color and odor. We then heated the substance and recorded the observation. The next tube we added cold water and observed the effects‚ then we heated it

Abstract: The objective of Experiment 1 was to observe some chemical changes. While observing the chemical changes in elements I also experimented with household cleaners to see how much chemical properties relate to our daily lives. Chemical changes occur all around me and I go without noticing them all the time without a second thought. This experiment opens my eyes to different chemical reactions occurring around me. This experiment also shows the importance of dilution. If I did not dilute something

Newberg Chemical Weapons Convention Historically chemical weapons are rarely seen in combat but when they are they are used to great effect‚ killing thousands and injuring many more. Chemical weapons were first used in combat in May 1915 when the Germans released chlorine gas against the French in the Battle of Ypres. Over the course of WWI new chemical agents were developed including cyanide‚ phosgene and mustard gas. The Geneva Protocol of 1925 condemned chemical weapons but states that if a

Danger: Chemical Sunscreens Sunscreen is meant to be a product designed to protect the skin from the sun. The first form of sunscreen was a red‚ petroleum jelly like substance that was mainly used to aid troops during WWII‚ it then transformed into a sort of pasty‚ white substance of zinc oxide. As the years passed and society began to evolve into one that craved sun kissed skin‚ many companies started to brainstorm in search of a new kind of sunscreen. The formula they aimed for was one that protected

Experiment 1: Observations of Chemical Changes Abstract: In the lab 1 experiment‚ the objective was to observed properties of various chemical reactions between twelve different basic compounds. Each reaction revealed chemical properties consisting of color change‚ CO2 gas formation‚ and/or precipitate formation. Certain reactions made it possible to distinguish between an acid and a base. Through the results of this experiment‚ chemical properties observed in the reactions could be used to associate
