\nThe mass of the carbon dioxide formed is 4.4 g.
\n<\/section>\n
\nAccording to the Law of Conservation of Mass, the total mass of the reactants in a chemical reaction is equal to the total mass of the products. In this decomposition reaction, Calcium Carbonate (CaCO\u2083) decomposes into Calcium Oxide (CaO) and Carbon Dioxide (CO\u2082).
\n<\/section>\n
\nGiven: Mass of reactant (CaCO\u2083) = 10 g. Mass of one product (CaO) = 5.6 g. Let the mass of the other product (CO\u2082) be ‘m’. Applying the Law of Conservation of Mass: Mass of CaCO\u2083 = Mass of CaO + Mass of CO\u2082. 10 g = 5.6 g + m. m = 10 g – 5.6 g = 4.4 g.
