1. Using values from Appendix C, calculate the standard
enthalpy change H rxn for the reaction
                    o




          SiCl4(l) + 2H2O(l)  SiO2(s) + 4HCl(g)


2. Write out the formation reactions for each compound in
the above reaction. Combine the formation reactions so that
they add to give the above reaction, and add the heats of
formation to verify your result for H rxn in question 1.
                                       o
