Need work step by step please!
In the chemistry lab, one often has to work with very reactive metals such as sodium and lithium. Unfortunately, these same metals can react vigorously with water or oxygen and cause fires. Given the following information: AH (kJ/mol) Li20(s) -597.9 Na20(s) -416 K20(s) -361 CO(9) -110.5 H20(1) -286 CCl4(1) -135 LICI(S) -409 KCI(S) -436 AH (kJ/mol) Li+ (aq) -278.5 Na+ (aq) -240 K+ (aq) -251 CO2(9) -393.5 OH(aq) -230 SiO2(s) -911 NaCl(s) -411 ci(aq)...

Using enthalpies of formation
(Appendix C), calculate ΔH ° for the following reaction at 25°C.
Also calculate ΔS ° for this reaction from standard entropies at
25°C. Use these values to calculate ΔG ° for the reaction at this
temperature. COCl2(g) + H2O(l ) h CO2(g) + 2HCl(g).
