For the reaction, C(graphite)+O2(g)→CO2(g), the enthalpy change for the reaction can also be written as ΔH∘formation and ΔH∘Combustion.
For the reaction, C(graphite)→C(gas), the enthalpy change for the reaction can also be written as ΔH∘formation and ΔH∘Atomization.
For the reaction, CH3COOH(aq)+OH−(aq)+H2O(l), the enthalpy change for the reaction can also be written as ΔH∘Neutralization.
