(a)
Interpretation:
The given equation has to be written complete and balanced
Concept Introduction:
Balanced Chemical equation:
A balanced chemical equation is an equation which contains same elements in same number on both the sides (reactant and product side) of the chemical equation thereby obeying the law of conservation of mass.
To Write: The given equation complete and balanced.
