Question

Hydrogen sulphide gas burns in air to give water and Sulphur Dioxide translate the following statement into chemical equation

Answer 1

2H2S + 3O2 》2H20 + 2SO2
hydrogen sulphide + oxygen 》 water + sulphur dioxide

Answer 2

Answer: $2H_2S+3O_2\rightarrow 2SO_2+2H_2O$

Explanation: The chemical reaction is written by writing down the chemical formulas of the reactants on the left hand side and the chemical formulas of products on the right hand side separated by a right arrow.

The number of atoms of each element must be same on both sides of the reaction so as to follow the law of conservation of mass which states that the mass of reactants must be equal to the mass of products.

$2H_2S+3O_2\rightarrow 2SO_2+2H_2O$
