Answer to Question #341957 in General Chemistry for Carrot

Question

1.Calculate the enthalpy change for the following chemical reaction:

SC2(l) + 3O@(g) --> CO2(g) + 2SO2(g)

1.C(s) + O2(g) --> CO2(g) ΔH° = - 393.5 kJ

2.S(s) + O2(g) --> SO2(g) ΔH° = - 296.8 kJ

3.C(s) + 2S(s) --> CS2(l) ΔH° = + 87.9 kJ

Answer 1

ΔH_reaction = ∑ΔH_products − ∑ΔH_reactants

ΔH_reaction =  (- 393.5 kJ + 2*(-- 296.8 kJ)) -  87.9 kJ = - 1075 kJ
