Answer 2

To burn 1 mole of $C_5H_{12}$ completely to obtain carbon dioxide and water, 8 moles of oxygen is required.

Explanation:

• The chemical equation depicting the combustion of $C_5H_{12}$ is as follows:

$C_5H_{12}+O_2\rightarrow 5CO_2+6H_2O$

• When the above given equation is examined, it is clear that the number of carbon atoms in reactant side and product side are equal. That is in both side carbon has 5 atoms.
• On the other hand, the same is the case with hydrogen. That is both sides, hydrogen has 12 atoms.
• When oxygen is considered, the number of moles is not equal on both sides.
• Thus to make it balance, in the reactant side 8 is included with oxygen as shown:

$C_5H_{12}+8O_2\rightarrow 5CO_2+6H_2O$

• Now both the reactant side as well as the product side has the same number of oxygen.
• Thus it is inferred that 8 moles of oxygen are required for complete combustion of 1 mole of $C_5H_{12}$.
