Q. No.Enthalpy of combustion of carbon to carbon dioxide is \(-390.0~\text{kJ mol}^{-1}.\) The amount of heat released when \(35.0~\text{g}\) of \(\mathrm{CO_2}\) is formed from the reaction of carbon and dioxygen gas, is:
1. \(310~\text{kJ}\)
2. \(490~\text{kJ}\)
3. \(245~\text{kJ}\)
4. \(700~\text{kJ}\)
1. \(310~\text{kJ}\)

What is the correct relationship between changes in enthalpy and internal energy within the following options?
1. \(\Delta \mathrm{H}+\Delta \mathrm{U}=\Delta \mathrm{nR} \)
2. \(\Delta \mathrm{H}=\Delta \mathrm{U -\Delta n_gRT}\)
3. \(\Delta \mathrm{H}=\Delta \mathrm{U+\Delta n_gRT }\)
4. \(\Delta \mathrm{H} -\Delta \mathrm{U=-\Delta n_gRT}\)
1. \(\Delta \mathrm{H}+\Delta \mathrm{U}=\Delta \mathrm{nR} \)
2. \(\Delta \mathrm{H}=\Delta \mathrm{U -\Delta n_gRT}\)
3. \(\Delta \mathrm{H}=\Delta \mathrm{U+\Delta n_gRT }\)
4. \(\Delta \mathrm{H} -\Delta \mathrm{U=-\Delta n_gRT}\)
