Calculate the enthalpy of the reaction 4B (s) + 302 (g) -> 2B₂O3(s) given the following pertinent information: 1. B2O3 (s) + 3H₂O(g)→302 (g) + B₂ H6 (g), ΔH = +2035 kJ 2. 2B(s) + 3H₂(g) →B₂ H6 (g), ΔH = +36 kJ 3. H₂(g) + O2(g) →H₂O(l), ΔH = -285 kJ 4. H₂O(1)→H₂O(g), ΔH = +44 kJ Express your answer with the appropriate units.
