Question

balance the equation HNO3 + H2S reacts NO2 + H2O + S

Answer 1

4hno3+h2s react 4no2+3h2o+s

Answer 2

The balanced chemical equation is $2HNO_3+H_2S\rightarrow 2NO_2+2H_2O+S$

Explanation:

Every balanced chemical equation follows law of conservation of mass.

A balanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

The balanced chemical equation for the given reaction follows:

$2HNO_3+H_2S\rightarrow 2NO_2+2H_2O+S$
