Standard heat of formation of `CH_(4),CO_(2)` and `H_(2)O_((g))` are `-76.2,-394.8` and `-241.6kJ mol^(-1)` respectively. Calculate the amount of heat evolved by burning `1m^(3)` of `CH_(4)` measured under normal conditions.

Explanation

To calculate the amount of heat evolved by burning 1 m³ of CH₄ under normal conditions, we can follow these steps:

### Step 1: Write the balanced chemical equation for the combustion of methane (CH₄).
The balanced equation for the combustion of methane is:
\[ \text{CH}_4(g) + 2\text{O}_2(g) \rightarrow \text{CO}_2(g) + 2\text{H}_2\text{O}(g) \]

### Step 2: Use the standard heat of formation values.
The standard heat of formation (\( \Delta H_f^\circ \)) values given are:
