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. \(\Delta \mathrm{H} -\Delta \mathrm{U=-\Delta n_gRT}\)
