Now that you have moles of CaO, determine how many grams of product he should have found in the end (you will need to calculate the molar mass of CaO)
Read the passage and use the equation to answer the rest of the questions. The molecule Caco, is what makes up eggshells, and it can decompose (break down) when heated strongly. This decomposition reaction is given by the equation: Caco,(s) - CaO(s) + CO,(g) Your friend argues that the chemical equation doens't follow the law of conservation of mass. He says, "Moles are not conserved since 1 mole of reactants produced 2 moles of product. This means the mass is higher in the end." You think he's wrong, and want to explain and do an experiment to prove it.
