Each of the gas evolution reaction is to be completed and to be balanced. Concept Introduction: Chemical equations having an equal number of atoms of each type on both sides are known as a balanced chemical equation. The steps to balance chemical equation are: If there is an element that occurs in only one compound on both sides of the equation, balance it first. If there are more than one such element is there, balance metals before non-metals. If the element is present in a free state on both the sides of the equation, balance it last. These elements are balanced by adjusting the coefficients. If coefficients are present in a fraction, convert it into whole numbers by multiplying with the appropriate number.

Each of the gas evolution reaction is to be completed and to be balanced.
Concept Introduction:
Chemical equations having an equal number of atoms of each type on both sides are known as a balanced chemical equation.
The steps to balance chemical equation are:
If there is an element that occurs in only one compound on both sides of the equation, balance it first.
If there are more than one such element is there, balance metals before non-metals.
If the element is present in a free state on both the sides of the equation, balance it last. These elements are balanced by adjusting the coefficients.
If coefficients are present in a fraction, convert it into whole numbers by multiplying with the appropriate number.
