Concept explainers
(a)
Interpretation:
The chemical equation for the following reaction needs to be determined.
Concept introduction:
A decomposition reaction is one in which a single compound splits into two or more elements or new compounds. In general, decomposition reactions are expressed as follows.
Answer to Problem 87A
The chemical equation is as follows:
Explanation of Solution
Decomposition reaction of
The above reaction is a decomposition reaction as the reactant split into two different elements. The number of atoms participating in the reaction that is in both reactant and product side is equal. Therefore, the chemical equation is balanced.
