Standard enthalpy of formation is the change of enthalpy during the formation of 1 mole of substance from its constituent elements, with all substances in their standard states.
RuHCO3 has four elements.
Elemental state of Rubidium = Rb (s)
Elemental state of Hydrogen = H2 (g)
Elemental state of Carbon = C (s)
Elemental state of Oxygen = O2 (g)
In the formation reaction, 1 mole of RuHCO3 is formed from its constituent elements.
So, the formation reaction is
Rb (s) + ½ H2(g) + C (s) + 3/2 O2(g) ---------> RbHCO3(s)
