The elements included in this balanced chemical equation are carbon, hydrogen and oxygen. As shown in the picture down below, in the reactant there are 2 acetylene and five oxygen.In the product are four carbon dioxide and two water. Acetylene is a chemical compound of carbon and hydrogen.
Law of conservation of matter states that matter cannot be created or destroyed. To satisfy this law, we have to balanced the chemical equation. In this chemical equation(2C2H2 + O2 -----> 4CO2 + H2O), it satisfy the law as there are no new atoms that are added or destroyed, they are just moved. In this chemical equation the number of different atoms of elements in the reactants side are equal to the number of different atoms of elements in the product side.
Acetylene is a colorless and odorless gas used as a fuel and a chemical building block. Molecule weight of acetylene is 26.04 lb/mol. Boiling point is at -119.6 degree Fahrenheit, melting point at -113.4 degree Fahrenheit. Liquid density of acetylene is 23.61 lb/ft3 at 70 degree Fahrenheit, gas density is 0.0677 lb/ft3 at 70 degree Fahrenheit. These are the physical properties of acetylene. Acetylene decompose very slowly at a normal temperature but decompose rapidly 780 degree Celsius. The amount of carbon to hydrogen is so large that this hydrocarbon behaves as a feeble acid. But it is not sufficiently ionized in aqueous solution to show an acid reaction. These are the chemical property of acetylene.
