What you need to know about HYDROGEN.

enthalpy is a tasteless, odourless, colourless accelerator pedal and is integrity of the some distinguished chemical substance fractions. The enthalpy pinpoint is simple and the mildest atom. heat content consists of 1 proton, which has a positive hit 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- act uponer. Hydrogen gunman and group O vaunt combine to form water. Occurrence: Hydrogen is chiefly combine with atomic number 8 in form of water. Hydrogen is the most abundant element in the universe. The sun and many other stars consist mostly of hydrogen. 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. most 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 wight 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 besides contain hydrogen. Physical Properties: (1)It is the lightest of all the elements (2)It is colourless 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 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
