percent of the total mass on earth)‚ it is considered to be the most abundant element in the entire universe. It is a gaseous element with the atomic symbol being H. It is usually categorized under the first group of the periodic table known as the alkali metals. It contains only one electron that revolves around one single energy level and it is the only element that is able to exist without any neutrons in its nucleus. It is diatomic‚ meaning that its molecules are composed of 2 atoms‚ yet it is

Biodiesel It refers to a vegetable oil- or animal fat-based diesel fuel consisting of long-chain alkyl (methyl‚ propyl or ethyl) esters. Biodiesel is typically made by chemically reacting lipids (e.g.‚ vegetable oil‚ animal fat (tallow[1][2])) with an alcohol producing fatty acid esters. Biodiesel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines. Biodiesel can be used alone‚ or blended with petro diesel

Acid and base are corrosive‚ irritating to the skin and often release choking vapor. So avoid in contact with your skin‚ eye and skin protection should always be worn when using them. * Transfer by dropper only small amounts at a time. * Have alkali or acid on hand for neutralization in order to minimize the threat caused by accident spill of acid or base. * Neutralization

the German company Bayer in 1897. Acetylsalicylic acid (ASA) decomposes rapidly in solutions of ammonium acetate or of the acetates‚ carbonates‚ citrates or hydroxides of the alkali metals. ASA is stable in dry air‚ but gradually hydrolyses in contact with moisture to acetic and salicylic acids. In solution with alkalis‚ the hydrolysis proceeds rapidly and the clear solutions formed may consist entirely of acetate and salicylate. Aspirin is readily broken down in the body to salicylic acid‚
