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 _____.(1 point)

35 g
35 g

11 g
11 g

27 g
27 g

20 g

Answer 1

In a chemical reaction, the law of conservation of mass states that the total mass of the reactants must equal the total mass of the products.

Here, the total mass of the reactants is:
- Mass of reactant 1 = 12 g
- Mass of reactant 2 = 23 g

Total mass of reactants = 12 g + 23 g = 35 g

The total mass of the products includes product 1 and product 2. We are told that the mass of product 1 is 15 g, so we can set up the equation:

Total mass of products = Mass of product 1 + Mass of product 2
35 g = 15 g + Mass of product 2

To find the mass of product 2, we can rearrange the equation:

Mass of product 2 = 35 g - 15 g
Mass of product 2 = 20 g

Therefore, the mass of product 2 is **20 g**.
