A
Answer to Problem 39E
The balanced equation for the decomposition reaction of solid cobalt
Explanation of Solution
Solid cobalt
The unbalanced equation for the decomposition reaction of solid cobalt
The numbers of atoms of elements on the left side of the reaction are not equal to the right side of the reaction. Therefore, the reaction is unbalanced.
A coefficient of
Therefore, the balanced equation for the decomposition reaction of solid cobalt
The numbers of atoms of each element on the left side of the reaction are equal to that on the right side of the reaction. Therefore, the reaction is balanced.

(b)
Interpretation:
The balanced equation for the decomposition reaction of solid tin
Concept introduction:
A chemical reaction is a process in which rearrangement of atoms or ions takes place between two reacting species. A balanced chemical equation represents an equation in which all the reactants and products are written with their stoichiometric coefficient and physical states. The number of atoms of an element on both sides of the equation is equal.
