Question

The law of conservation of matter states that matter can be neither created nor destroyed. Your friend shows you the following chemical equation: The equation was CaCO3 →CaO+CO2
He says that because the oxygen atoms are split between two different molecules in the products, the equation does not support the law of conservation of matter. Is your friend right? Explain your answer. Draw a model showing the number of each type of atom in the reactants and products. Use your model to explain your answer.

PLEASE HELP

Answer 1

Yes, our friend is right, because there is no contradiction to the law of conservation of mass in the above equation. It just the mass of the product is equal to the mass of reactants.. and that is shown in the equation you have presented earlier
