**Thermochemical Equation Balancing**

When \( \text{CO}_2(g) \) reacts with \( \text{H}_2(g) \) to form \( \text{CO}(g) \) and \( \text{H}_2\text{O}(g) \), 41.2 kJ of energy are absorbed for each mole of \( \text{CO}_2(g) \) that reacts. 

**Objective:** Write a balanced thermochemical equation for the reaction, including an energy term in kJ as part of the equation. Note that the answer box for the energy term is case sensitive.

**Instructions:**
Use the smallest integer coefficients possible and place the energy term in the last box on the appropriate side of the equation. Leave any unused boxes blank.

**Layout:**

\[ 
\text{[Box]} \quad \text{CO}_2(g) + \text{[Box]} \quad \text{H}_2(g) \rightarrow \text{[Box]} \quad \text{CO}(g) + \text{[Box]} \quad \text{H}_2\text{O}(g) + \text{[Box]} \quad 41.2 \text{ kJ}
