For each of the following reactions, the enthalpy change written is that measured when the numbers of moles of reactants and products taking part in the reaction are as given by their coefficients in the equation. Calculate the enthalpy change when 1.00 gram of the underlined sub- stance is consumed or produced. (a) 4 Na(s) + O2(g). ΔΗ-828 k] CaO(s) + MgO(s) + 2 CO2(g) ΔΗ-+302 k] 2 Na20(s) (b) CaMg(CO3)2 (s) (c) H2(g)+ 2 CO(g) - H2O2(€) + 2 C(s) ΔΗ-+ 33.3 k]
