Question

write the equation for the following reactants undergoing combustion. balance the equation.

1. c₆h₁₂o₆

skeleton equation
balanced equation

Explanation:

Step1: Write skeleton equation

Combustion of $\text{C}_6\text{H}_{12}\text{O}_6$ uses $\text{O}_2$ and produces $\text{CO}_2$ and $\text{H}_2\text{O}$: $\text{C}_6\text{H}_{12}\text{O}_6 + \text{O}_2
ightarrow \text{CO}_2 + \text{H}_2\text{O}$

Step2: Balance C atoms

6 C on left → 6 $\text{CO}_2$: $\text{C}_6\text{H}_{12}\text{O}_6 + \text{O}_2
ightarrow 6\text{CO}_2 + \text{H}_2\text{O}$

Step3: Balance H atoms

12 H on left → 6 $\text{H}_2\text{O}$: $\text{C}_6\text{H}_{12}\text{O}_6 + \text{O}_2
ightarrow 6\text{CO}_2 + 6\text{H}_2\text{O}$

Step4: Balance O atoms

Right: $6×2 + 6×1 = 18$ O; left: 6 O in $\text{C}_6\text{H}_{12}\text{O}_6$ → need 12 O from $\text{O}_2$ → 6 $\text{O}_2$: $\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2
ightarrow 6\text{CO}_2 + 6\text{H}_2\text{O}$

Answer:

Skeleton Equation: $\text{C}_6\text{H}_{12}\text{O}_6 + \text{O}_2
ightarrow \text{CO}_2 + \text{H}_2\text{O}$
Balanced Equation: $\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 = 6\text{CO}_2 + 6\text{H}_2\text{O}$
