Solution: Calculate the change in energy for the following
Chapter 8, Problem 88P(choose chapter or problem)
Calculate the change in energy for the following processes:
(a) \(\mathrm{Mg}(g)+2 \mathrm{~F}(g) \longrightarrow \mathrm{Mg}^{2+}(g)+2 \mathrm{~F}^{-}(g)\)
(b) \(2 \mathrm{Al}(g)+3 \mathrm{O}(g) \longrightarrow 2 \mathrm{Al}^{3+}(g)+3 \mathrm{O}^{2-}(g)\)
The electron affinity of \(\mathrm O^-\) is −844 kJ/mol.
