The standard enthalpy of combustion at `25^(@)C` of hydrogen, cyclohexene `(C_(6)H_(10))`, and cyclohexane `(C_(6)H_(12))` are `-241,-3800`, and `-3920 kJ mol^(-1)` repectively. Calculate the heat of hydrogenation of cyclohexene.

Explanation

To calculate the heat of hydrogenation of cyclohexene (C₆H₁₀), we will use the given standard enthalpy of combustion values for hydrogen, cyclohexene, and cyclohexane. The process involves writing the combustion reactions and manipulating them to derive the heat of hydrogenation.

### Step-by-Step Solution:

1. **Write the combustion equations**:
- For hydrogen (H₂):
\[
\text{H}_2 + \frac{1}{2} \text{O}_2 \rightarrow \text{H}_2\text{O} \quad \Delta H = -241 \text{ kJ/mol}
