    a. 6 C(graphite) + 6 H2(g) + 3 O2(g) --> C6H12O6(s)

    b. 3 Ca(s) + 2 P(s) + 4 O2(g) --> Ca3(PO4)2(s)

    B. If you have a table of standard enthalpies of formation, you can do this using the idea that:

    Delta Hrxn = sum of Delta Hof of products - sum of Delta Hof of reactants

    Delta Hrxn = 3 (Delta Hof CO2) - [Delta Hof Fe2O3) + 3(Delta Hof CO)]
