add the following thermochemical equations: (1) P4(s) + 6Cl2(g) => 4PCl3(g) chg of H= -1148kJ (2) 4PCl3(g)+4Cl2(g) =>4PCl5(g) chg of H=-460kJ (3) overall equation= ? chg of H overall= ? Select the correct chg of H for the overall process (equation 3) A. -688 kJ B. 688 kJ C. -1608 kJ D. 1608 E. none of these i don't even really understand the question, any help? this is my first time using open study...
