Question

The table shows the number of reactants and products present during two separate chemical reactions.

Answer 1

Answer: Option (a) is the correct answer.

Explanation:

A decomposition reaction is defined as a reaction where a compound dissociates into two or more atoms.

For example, $A \rightarrow B + C + D$

Whereas a chemical reaction in which two reactants combine together to result in the formation of a compound is known as a synthesis reaction.

For example, $A + B \rightarrow C$ is a synthesis reaction.

Thus, we can conclude that the statement chemical reaction A, because the reactant is a compound identifies the decomposition reaction and describes a substance is involved.
