(a)
Interpretation:
The given equation should be completed and balanced.
Concept Introduction:
Deciding which products will form when two or more reactants added together is not an easy task without any experimental evidences. The best way to predict what products will form is to think of various possibilities and then decide which product is most likely to form.
