Calculate the heat of formation of glucose from the following data,
`C(s) + O_2(g) to CO_2(g) , DeltaH =-395.0 kJ`
`H_2(g) + 1/2O_2(g) to H_2O (l) , DeltaH = - 269.4 kJ`
`C_6H_12O_6 (s) + 6O_2(g) to 6CO_2(g) + 6H_2O(l), DeltaH =- 2900 kJ`

Explanation

To calculate the heat of formation of glucose (C₆H₁₂O₆) using the provided thermodynamic data, we will follow these steps:

### Step 1: Write down the equations and their enthalpy changes
1. **Combustion of carbon:**
\[ C(s) + O_2(g) \rightarrow CO_2(g) \quad \Delta H = -395.0 \, \text{kJ} \]
