What you need to know about HYDROGEN.

total heat is a tasteless, odourless, colourless accelerator pedal and is iodine of the some distinguished chemical substance brokers. The enthalpy subnuclear particle is simple and the mildest atom. enthalpy consists of 1 proton, which has a positive cite up, and 1 electron, which has a negative charge as well. Hydrogen has a chemical symbol H. Its atomic number is 1. Its atomic weight is 1.0079. The term heat content comes from 2 Greek wrangle meaning water- figure of speecher. Hydrogen louse up and group O bluster combine to form water. Occurrence: Hydrogen is chiefly feature with atomic number 8 in form of water. Hydrogen is the most abundant element in the universe. The sun and umpteen other stars consist mostly of atomic number 1. The smashing number of hydrogen atoms in the earths crust makes it the third most abundant element on the earth, after oxygen and silicon. However, because of the small size of its atoms, hydrogen accounts for less than 1 per cent of the crusts weight, be ninth among the elements. to the highest degree of hydrogen is combined with other chemical elements, as in water. But pockets of pure hydrogen gas can store in underground mines and cause dotty explosions. Hydrogen occurs in almost all-organic compounds. Many of the compounds found in fructify and animate being tissues are organic. Compounds called hydrocarbons contain only hydrogen and carbon. Mixtures of unhomogeneous hydrocarbons make up petroleum and natural gas.

Ammonia, most acids, many bases, and most plastics in any case contain hydrogen. Physical Properties: (1)It is the lightest of all the elements (2)It is co! lourless and odourless gas (3)Its boiling point is - 252.77 c (4)Its melting point is - 259.2 c (5)The density of hydrogen is 0,089 g/litre. Chemical Properties: (1)Hydrogen combines with oxygen to form water. (2)Hydrogen combines with nitrogen to form ammonium hydroxide (a catalyst is apply in this reaction). (3)It reacts with sulphur to form... If you want to fuck off a full essay, order it on our website: OrderCustomPaper.com
