Enthalpy of combustion of carbon to `CO_(2)` is `-393.5 kJ mol^(-1)`. Calculate the heat released upon formation of `35.2 g` of `CO_(2)` from carbon and dioxygen gas.

Explanation

To calculate the heat released upon the formation of 35.2 g of CO₂ from carbon and dioxygen gas, we can follow these steps:

### Step 1: Understand the Reaction
The combustion of carbon to form carbon dioxide (CO₂) can be represented by the following balanced chemical equation:

\[ C + O_2 \rightarrow CO_2 \]

The enthalpy change (ΔH) for this reaction is given as -393.5 kJ/mol. This means that when 1 mole of carbon combusts, 393.5 kJ of heat is released.
