Extra Credit Caper #1 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 Due Fri 4/11 by 5:00!
