Cаlculаte the ΔH°rxn fоr the decоmpоsition of cаlcium carbonate to calcium oxide and carbon dioxide. ΔH°f [CaCO3(s)] = –1206.9 kJ/mol; ΔH°f [CaO(s)] = –635.1 kJ/mol; ΔH°f [CO2(g)] = –393.5 kJ/mol CaCO3(s) → CaO(s) + CO2(g) Write out your calculations and answers clearly, with all numbers labeled correctly, on a piece of paper. Right after submitting your exam, upload your photos to the Assignment Box, "Calculations for Exam 4 (Chapter 5 and 6)"
