Calculate the enthalpy of the reaction 4B(s)+3O2(g)→2B2O3(s)
Added by Lillian W.
Step 1
The enthalpy of formation is the energy change when one mole of a substance is formed from its elements in their standard states. The standard enthalpy of formation for B2O3(s) is -1273.6 kJ/mol. For elemental substances like B(s) and O2(g), the standard enthalpy Show more…

Calculate the enthalpy of the reaction 4B(s) + 3O2(g) -> 2B2O3(s) given the following pertinent information: A. B2O3(s) + 3H2O(g) -> 3O2(g) + B2H6(g), ΔrH°A = +2035 kJ mol-1 B. 2B(s) + 3H2(g) -> B2H6(g), ΔrH°B = +36 kJ mol-1 C. H2(g) + 1/2O2(g) -> H2O(l), ΔrH°C = -285 kJ mol-1 D. H2O(l) -> H2O(g), ΔrH°D = +44 kJ mol-1 Express your answer with the appropriate units.
