If you wanted to, you could ask what the heat of formation is of a given compound such as diphosphorus pentasulfide, but if you want to know about a heat of reaction, you have to specify a reaction. A compound is not a reaction.
The formula of diphosphorus textroxide is P2O4.
Tetra phosphorous pentasulfide
This the heat released during a chemical reaction.
diphosphorus pentaselenide
Diphosphorus Pentoxide
The correct name is dimanganese pentasulfide.
The name of the covalent bond is diphosphorus pentasulfide
The name of the compound P3F4 is triphosphorus tetrafluoride.
P2S5 is molecular. The molecular formula is P4S10. It structure is the same as the molecular form of P2O5, which is P4O10. The compound is normally called simply phosphorus pentasulfide, however a more correct name diphosphorus pentasulfide.
This reaction is:P4 + 3 O2 = P4O6
40HNO3 + As2S5 --------> 5H2SO4 +2H3AsO4 + 40NO2 + 12H2O
This compound is the arsenic pentasulfide.
The allotrope diphosphorus is P2.
The formula of diphosphorus textroxide is P2O4.
dinitrogen pentasulfide N2S5 therefor 5 sulfur atoms

Heat of a reacion is the totall amount of heat a reaction produces. Molar heat of a reaction is the heat produced/mol if you have the molar hear of the reaction you can calculate the heat of the reaction based on the moles of reactants you have
