🤓 Based on our data, we think this question is relevant for Professor Moon's class at UNL.
Calculate Δ Hrxn for the following reaction:
CaO(s) + CO2 (g) ---> CaCO3 (s)
Use the following reactions and given Δ H values:
Ca(s) + CO2(g) + 1/2 O2(g) --> CaCO3 (s), ΔH = -812.8 kJ
2Ca(s) + O2 (g) --> 2CaO(s), ΔH = -1269.8 kJ
Express your answer using four significant figures.
