Answer to Problem 69E
The balanced chemical equation for the reaction between propanol and oxygen gas is shown below.
Explanation of Solution
Alcohols react in the presence of oxygen to give carbon dioxide and water. This reaction is known as combustion reaction. Propanol reacts with oxygen to form carbon dioxide and water.
The unbalanced chemical equation for the reaction between propanol and oxygen gas is as shown below.
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.
Propanol is multiplied by the coefficient two, oxygen gas by nine. On the right side, carbon dioxide is multiplied by six and water is multiplied by eight.
Therefore, the balanced chemical equation for the reaction between propanol and oxygen gas is shown below.
The numbers of atoms of each element on the left side of the reaction are equal to the right side of the reaction. Therefore, the reaction is balanced.

Concept introduction:
A chemical reaction is a process in which rearrangement of atom 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.
