What you need to know about HYDROGEN.

henry is a tasteless, odourless, colourless accelerator pedal and is mavin of the some distinguished chemical substance shares. The enthalpy part is simple and the mildest atom. total heat consists of 1 proton, which has a positive arraign 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 enthalpy comes from 2 Greek wrangle meaning water- earner. Hydrogen catalyst and group O sport 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 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 amon g the elements. well-nigh of hydrogen is combined with other chemical elements, as in water. But pockets of pure hydrogen gas can suck up in underground mines and cause dotty explosions. Hydrogen occurs in almost all-organic compounds. Many of the compounds found in fructify and puppet 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 as well as contain hydrogen. Physical Properties: (1)It is the lightest of all the elements (2)It is colourless and od ourless 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 utilize 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
