Question

In a chemical reaction, two molecules are rearranged to produce two new molecules. Reactant 1 has a mass of 12 g. Reactant 2 has a mass of 23 g. The mass of product 1 is 15 g. The mass of product 2 is _____.

Answer 1

The mass of Product 2 is -4 g.

Step-by-step explanation:

According to the Law of Conservation of Mass, matter (and mass) cannot be created or destroyed in a chemical reaction - it can only change forms. So the mass of the products should be equal to the mass of the reactants. In this case, Reactant 1 has a mass of 12 g and Reactant 2 has a mass of 23 g. The mass of Product 1 is 15 g. Therefore, to find the mass of Product 2, we can subtract the mass of Reactant 1 (12 g) and the mass of Product 1 (15 g) from the total mass of Reactant 2 (23 g):

Mass of Product 2 = Mass of Reactant 2 - Mass of Reactant 1 - Mass of Product 1
Mass of Product 2 = 23 g - 12 g - 15 g
Mass of Product 2 = 23 g - 27 g
Mass of Product 2 = -4 g

Therefore, the mass of Product 2 is -4 g.
