When heating calcium carbonate, a decomposition reaction occurs, forming calcium oxide and carbon dioxide gas while following the Law of Conservation of Mass. This reaction is endothermic, absorbing heat energy and causing a cooling effect.
Heating calcium carbonate results in a decomposition reaction, producing calcium oxide and carbon dioxide gas. This process involves breaking down a compound into its constituent elements by applying heat.
For example, the equation CaCO3 + heat → CaO + CO2 demonstrates this reaction. The Law of Conservation of Mass ensures that the mass of reactants equals the mass of products in a chemical reaction, as shown through experimental observations.
Endothermic reactions, like the decomposition of calcium carbonate, absorb heat energy from the surroundings as the reaction proceeds, leading to a cooling effect.
