Consider following reaction: HgO (s) -> Hg(l) + ½ O2 (g) Delta H = +90.7 kj/mol. What quantity of heat in kj/mol is required to produce one mole HgO? Write your answer without units.
Given the following data
2ClF(g) + O2(g) --> Cl2O(g) + F2O (g) Delta H= 167.4 kJ I
2ClF3(g) + 2O2(g) --> Cl2O(g) + 3F2 O (g) Delta H= 341.4 kJ II
2 F2(g) + O2(g) ---> 2F2O (g) Delta H= -43.4 kJ III
Calculate the delta H in kJ for below reaction:
ClF(g) + F2(g) ---> ClF3(g)
