Q.The standard enthalpy of combustion of $C(s)$ is $-393.5 \text{ kJ/mol}$ . The heat released upon formation of $35.2 \text{ g}$ of $CO_2$ from carbon and oxygen gas is:

-314.8 \text{ kJ}

-393.5 \text{ kJ}

-629.6 \text{ kJ}

-31.48 \text{ kJ}

The correct solution involves applying the fundamental concept to derive the final value step by step...
