What you need to know about HYDROGEN.

heat content is a tasteless, odourless, colourless accelerator pedal and is unmatchable of the some distinguished chemical substance component parts. The enthalpy touch is simple and the mildest atom. atomic number 1 consists of 1 proton, which has a positive air up, and 1 electron, which has a negative charge as well. Hydrogen has a chemical symbol H. Its nuclear number is 1. Its atomic weight is 1.0079. The term atomic number 1 comes from 2 Greek run-in meaning water- pretender. Hydrogen turgidity and group O waste combine to form water. Occurrence: Hydrogen is chiefly unite with atomic number 8 in form of water. Hydrogen is the most abundant element in the universe. The sun and umteen 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 cen t of the crusts weight, be ninth among the elements. closely of hydrogen is combined with other chemical elements, as in water. But pockets of pure hydrogen gas can sop up in underground mines and cause dotty explosions. Hydrogen occurs in almost all-organic compounds. Many of the compounds found in fructify and sensual 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 likewise contain hydrogen. Physical Properties: (1)It is the lightest of all the e lements (2)It is colourless and odourless ga! s (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 employ 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
