Calcium carbonate is a white mineral. A chemist burns calcium carbonate, CaCO3, to produce carbon dioxide, CO2, and a white powder, CaO. The chemical equation for this reaction is CaCO3 → CO2 + CaO. Compare the properties of the products and reactants in this reaction. Use numbers of atoms to describe the amounts of calcium, carbon, and oxygen before and after the reaction. Explain where the equation shows the conservation of matter.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
