Question

A 54g sample of carbon combines with 13g of Oxygen to for Carbon dioxide. a) what is the mass of the reactants? b) what is the mass of the products? c) How do you know? What data or process did you use to find your answer?

Answer 1

The mass of the reactants is 67g, and the mass of the products is 54g. These values are determined based on the balanced chemical equation and the law of conservation of mass.

Step-by-step explanation:

a) In order to find the mass of the reactants, we add the mass of carbon and the mass of oxygen. So, the mass of the reactants is 54g + 13g = 67g.

b) To find the mass of the products, we look at the balanced equation and see that carbon dioxide is the only product. So, the mass of the products is 54g.

c) We know these values because they are determined based on the balanced chemical equation and the law of conservation of mass. The law of conservation of mass states that mass is neither created nor destroyed during a chemical reaction. Therefore, the mass of the reactants must equal the mass of the products.
