Glycine, C2H5O2N, is important for biological energy. The combustion reaction of glycine is given by ...

Glycine, C₂H₅O₂N, is important for biological energy. The combustion reaction of glycine is given by the equation
4C₂H₅O₂N(s) + 9O₂(g) → 8CO₂(g) + 10H₂O(l) + 2N₂(g) ΔH°_rxn = –3857 kJ/mol
Given that ΔH°_f[CO₂(g)] = –393.5 kJ/mol and ΔH°_f[H₂O(l)] = –285.8 kJ/mol, calculate the enthalpy of formation of glycine.

▸ –3,178 kJ/mol

▸ –964 kJ/mol

▸ –537.2 kJ/mol

▸ –268.2 kJ/mol

▸ 2,149 kJ/mol
