The scientific law that supports the prediction is **the law of conservation of mass**. This law states that mass is neither created nor destroyed in a chemical reaction, meaning the total mass of the reactants (copper and sulfur) will equal the total mass of the products. In this case, the scientist correctly predicts that the total mass of the reactants (12.7 g of copper + 3.2 g of sulfur = 15.9 g) will equal the mass of the product.
