Interpretation Introduction

(a)

Interpretation:

The incomplete reaction ${\text{Fe(s) + H}}^{+}\text{(aq) }\to$ should be completed and balanced.

Concept introduction:

A balanced chemical equation follows the law of conservation of mass. A balanced chemical equation has the same number of elements in the reactants side and the product side. Balancing a chemical equation is a trial and error method.

Interpretation Introduction

(b)

Interpretation:

The incomplete reaction ${\text{Ca(s) + H}}_2\text{O(l) }\to$ should be completed and balanced.

Concept introduction:
