Chemical Weapons Chemical weapons use the toxic properties of chemical substances rather than their explosive properties to produce physical or physiological effects on an enemy. Although instances of what might be styled as chemical weapons date to antiquity‚ much of the lore of chemical weapons as viewed today has its origins in World War I. During that conflict "gas" (actually an aerosol or vapor) was used effectively on numerous occasions by both sides to alter the outcome of battles. A significant

Topic: Silver is an ancient mineral that dates back since prehistoric times. One thing that makes silver so special is that it was one of the first five metals that we started to use. Silver is found in almost every electronic device there is‚ and as time progresses the usage of it increases‚ unfortunately the amount there is left decreases. How is it created or source of the mineral? (5) Silver is not originated from Earth‚ as it happens it came from space. Many elements were formed in the big

Chemical Reactions & Equations CHEMICAL REACTION : In a reaction when the original state of the particle changes and it cannot be reversed by simple physical means‚ this type of reaction is known as chemical reaction. Example :- Fermentation of grapes‚ burning of wood etc. In this reaction we have seen that after burning of wood‚ coal is formed and we cannot make wood from coal. PHYSICAL REACTION : In a reaction when original state of the particle can be recovered by any means then this type of

Assignment 5 Sheet Harbour Chemicals Sheet Harbour Chemicals (SHC) manufactures chemicals used in the paint industry. The process involves three departments. Chemical A‚ which is purchased for $3 per liter‚ is processed through Department 1 in batches of 100 liters. Each batch of chemicals processed through Department A produces 70 liters of chemical B and 30 liters of chemical C. Chemical B is sold for $10 per liter. Chemical C is used in Department 2 to produce chemicals D‚ E‚ and F. Department 2

Lab #3: Method of Initial Rates: Iodine Clock Introduction The detailed system of steps in a reaction is called the reaction mechanism‚ and it is one of the principal aims of chemical kinetics to obtain information to aid in the elucidation of these mechanisms in order to better understand chemical processes. Reactions usually occur in a stepwise manner with each step proceeding at a different speed. If the rate of reaction is slow enough to measure‚ this is indicative of a step much slower
