🤓 Based on our data, we think this question is relevant for Professor Johnson's class at GS.
Calculate the enthalpy of the reaction
4B(s) + 3O2(g) → 2B2O3(s)
given the following pertinent information:
B2O3(s) + 3H2O(g) → 3O2(g) + B2H6(g), ΔH∘A=+2035 kJ
2B(s) + 3H2(g) → B2H6(g), ΔH∘B=+36 kJ
H2(g) + 1/2 O2(g) → H2O(l), Δ H∘C=−285 kJ
H2O(l) → H2O(g), ΔH∘D=+44 kJ
Express your answer with the appropriate units.
