Agent Orange and the Effects It Had Because of the Vietnam War Tasha S. Samuelu CBRN SLC Class 002/003-13 Abstract Agent Orange is a chemical agent that was used in the Vietnam War between the years of 1962 and 1971. Without any knowledge of the damage that it can cause‚ it was spread across the southern part of Vietnam. Aerial Spray used by airplanes and helicopters was how the agent was spread throughout Vietnam. After the spread of the agent throughout the vegetation‚ there were some

Special Report Methyl ethyl ketone – A techno-commercial profile M ethyl ethyl ketone (MEK or 2-butanone) is an organic compound with the formula CH3C(O)CH2CH3. Its CAS number is 78-93-3. The colorless liquid ketone has a sharp‚ sweet odour of butterscotch and acetone. It is produced industrially on a large scale‚ and also occurs in trace amounts in nature. It is soluble in water and is commonly used as an industrial solvent. With natural and synthetic resins‚ MEK produces solutions with low viscosity

BRONSTED-LOWRY ACIDS AND BASES 1. The Bronsted-Lowry definition There are many definitions of acids and bases in existence‚ but the most useful one is the Bronsted-Lowry definition: An acid is a substance which can behave as a proton (re presented as a hydrogen ion‚ H+) donor. Any substance which contains hydrogen bonded to a more electronegative element can thus behave as an acid: HCl == H+ + Cl- H2SO4 == H+ + HSO4- A base is a substance which can behave as a proton acceptor. Any

by everyday pollution from houses‚ factories‚ cars‚ and etc. This is the concept of acid rain‚ which according to EPA.gov is a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Acid rain isn’t just rain‚ its forms like hail or snow‚ which is wet deposition‚ and smoke or dust‚ which is dry deposition. The effects of acid rain are quite terrifying bringing all types of problems to the Earth‚ for example

Title: Nitration of Methyl Benzoate Objective: To prepare methyl-3-nitrobenzene from nitration of methyl benzoate. Results and calculations: Density = 1.094 g/ml = Mass of methyl benzoate = 1.094 g/ml x 2.8 ml = 3.0632 g no. of mol of methyl benzoate = = 0.022499 mol 1 mol of methyl benzoate produced 1 mol of methyl m-nitrobenzene. Therefore‚ 0.022499 mol of methyl benzoate produced 0.022499 mol of methl
