Question

Which of the following is a chemical equation that contains both products and reactants?

Answer 1

Answer:

How about this one – the high-temperature decomposition of copper sulfate in the presence of hydrogen? (2 reactants, 4 products)

H2(g) + 2CuSO4 = 2CuO + 2SO2(g) + H2O(g) + 0.5O2(g) [T ≥ 500C]

Change in Free Energy: ΔG(500C) = -4.5kJ (negative, so the reaction runs)

Change in Enthalpy: ΔH(500C) = +373.6kJ (positive, so the reaction is endothermic)
