CHEM 103 Lab experiment 4 : Thermochemistry (Portage learning) Purpose: All chemical reactions result in some heat change. Heat changes are important not only in the laboratory but also in everyday life. Procedure: We looked at a basic combustion chemical reaction of methane plus water with a combustion reaction which produced Carbon dioxide and water: CH₄ (g) + 2o2 (g) Co2(g) + 2H2O(e) ΔH= -212.8kcal (Exothemic) CaCo3 CaO + CO2 ΔH = +42.4 Kcal (Endothermic energy coming in) Reverse: CaO + Co2 CaCo3 ΔH = -42.4Kcal (Energy Given up) For every 1 mol of CH₄ that burns, we get = -212.8 kcal Extensive Property For every 2 mol of CH₄ that burns, we get = -425.6 kcal Data/Results/Calculations:
