The balanced equation for the decomposition of sodium bicarbonate is 2 NaHCO3 (s) --> Na2CO3 (s) + H2O (g) + CO2 (g)delta H 129.2. Using the enthalpies of formation, calculate the enthalpy of formation of sodium bicarbonate.

  • Chemistry - ,

    dHrxn = (n*dHf products) - (n*dHf reactants)
    dHrxn = 129.2 kJ
    Substitute the others and solve for dH NaHCO3.
