Determine the bond dissociation energy of methane (CH4) using the following data: Reaction: CH4(g) → C(g) + 4H(g)ΔH°f (kJ/mol): CH4(g) = -74.81C(g) = 715.32H(g) = 218.00Hint: bond dissociation energy can be calculated using the formula ΔH°rxn = Σ (ΔH°f, products) - Σ (ΔH°f, reactants)

A student synthesized two coordination compounds containing the same metal ion, ligands, and donor atoms. However, the student found that the two compounds exhibited different physical and chemical properties. Explain the possible types of isomerism that could exist in these coordination compounds and how they can be distinguished.
