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) Responses 27 g 27 g 20 g 20 g 35 g 35 g 11 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.

In this case:

• Mass of Reactant 1 = 12 g
• Mass of Reactant 2 = 23 g
• Total mass of reactants = 12 g + 23 g = 35 g

You are given the mass of Product 1:

• Mass of Product 1 = 15 g

To find the mass of Product 2, you can use the following equation:

\[ \text{Total mass of products} = \text{Total mass of reactants} \]

Let \( P_2 \) be the mass of Product 2.

\[ 15 g + P_2 = 35 g \]

Now, solve for \( P_2 \):

\[ P_2 = 35 g - 15 g = 20 g \]

Therefore, the mass of Product 2 is 20 g.
