Answer

Balanced chemical equation: $C_5H_{12}(g) + 8O_2(g) --\gt 5CO_2(g) + 6H_2O(g)$

Work Step by Step

1. Identify the products and reactants: Reactants: $C_5H_{12}$ and $O_2$ Products: $CO_2$ and $H_2O$ 2. Write the unbalanced equation: $C_5H_{12}(g) + O_2(g) --\gt CO_2(g) + H_2O(g)$ 3. Balance the number of carbon atoms: $C_5H_{12}(g) + O_2(g) --\gt 5 CO_2(g) + H_2O(g)$ 4. Balance the number of hydrogen atoms: $C_5H_{12}(g) + O_2(g) --\gt 5CO_2(g) + 6H_2O(g)$ 5. There is a total of 16 oxygen atoms on the products side. Balance the number of $O$ atoms: $C_5H_{12}(g) + 8O_2(g) --\gt 5CO_2(g) + 6H_2O(g)$
