Heating of calcium carbonate equation
WebDetermine the standard enthalpy of formation of calcium carbonate from the thermochemical equations given below. Ca (OH)2 (s) → CaO (s) + H2O (l) Δ r H° = 65.2 kJ/mol-rxn Ca (OH)2 (s) + CO2 (g) → CaCO3 (s) + H2O (l) Δ r H° = −113.8 kJ/mol-rxn C (s) + O2 (g) → CO2 (g) Δ r H° = −393.5 kJ/mol-rxn WebThermal decomposition reactions are decomposition reactions that take place through heating. Thermal decomposition is a chemical change with new substances being produced. Metal carbonates thermally decompose into metal oxides and carbon dioxide gas. The presence of carbon dioxide gas can be tested using limewater.
