In order to test the claim, your friend heats 5.0 g of CaCO3 strongly for 10 minutes over a Bunsen burner flame to cause the chemical reaction to occur. You can see gases coming off. After cooling, he measures the mass of the products formed and finds it is 2.9 grams. END Mass: 2.9g START DURING Mass: 5.0g CaCO, being heated; gas bubbles in test tube He's highly confused, since he thought mass was being added, but it went down. Explain the change in mass of the products compared to the reactant.
