(a)
Interpretation: Representation of an unbalanced equation for the given set of reactions has to be given.
Concept Introduction:
- Chemical equation is the symbolic representation of a
chemical reaction using thesymbols of elements. Chemical equation must be balanced on both sides (reactant side and product side) of the reaction. - Chemical equation must be balanced why because only then the yield, kinetics, heat of formation, equilibrium constant etc., of a reaction can be calculated. The balanced chemical equation gives the ratio of reactants involved in the chemical reaction. The elements present on reactant side and product side must be same. The number of atoms present on reactant side must match the number of atoms on product side, thus the mass of reactant undergoing reaction will match the mass of products that comes out.
- A well-balanced chemical equation will obey the "Law of conservation of mass" which states that, "in a closed system, the mass of reactants will be equal to the mass of product. It can neither be created nor be destroyed."
- When a chemical equation is not balanced, "Law of conservation of mass" is not obeyed.
To write: An unbalanced equation for the given reaction.

The density of liquid water at 0 °C is 1.000 g cm³ and the density of ice at 0 °C is 0.915 g cm³. Note that this difference in density is the reason your water pipes burst if they freeze and why you shouldn't forget to take your bottle of pop out of the freezer if you put it in there to try and cool it down faster.
