Balance the following thermochemical equation with the lowest whole number coefficients, then use the table of bond enthalpies to determine:
A) the enthalpy of reaction, ΔrH∘
.
B) heat exchanged when 20.61 g of N2(g)
reacts (assume it is the limiting reactant).

Reaction: H2S(g)+N2(g)+H2O(g)⟶SO2(g)+NH3(g)
