The formula which shows the ratio of the number of atoms of different elements present in a molecule is called the empirical formula.

Decomposition of petroleum in absence of air at high temperature is called pyrolysis. 

Derlin polymer is produced when liquid solution of methanol is heated at a very low pressure.

The nuclear process in which nucleus of a larger and heavy element is broken into nucleus of smaller elements is called nuclear fission reaction.

The reactant which donates electron in a redox reaction is called reductant.

The reaction in which the reactants react and convert into products and the products react again and revert into reactants is called a reversible reaction.

In a chemical reaction, if the atoms are rearranged and one isomer is formed from another isomer, the reaction is called an isomerization reaction. An isomerization reaction is a type of chemical reaction in which a molecule undergoes a structural change to form a different isomer, which is a molecule with the same chemical formula … Read more

When all of the reactants of a chemical reaction turn into products, the reaction is called irreversible reaction.
