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 35 g 35 g 27 g 27 g 20 g 20 g 11 g

Answer 1

In a chemical reaction, the law of conservation of mass states that mass is neither created nor destroyed. Therefore, the total mass of the reactants must equal the total mass of the products.

Given:

• Mass of Reactant 1 = 12 g
• Mass of Reactant 2 = 23 g
• Mass of Product 1 = 15 g

First, calculate the total mass of the reactants: \[ \text{Total mass of reactants} = \text{Mass of Reactant 1} + \text{Mass of Reactant 2} = 12 , \text{g} + 23 , \text{g} = 35 , \text{g} \]

Next, let \(x\) be the mass of Product 2. According to the conservation of mass: \[ \text{Total mass of products} = \text{Mass of Product 1} + \text{Mass of Product 2} \] \[ 35 , \text{g} = 15 , \text{g} + x \]

Now, solve for \(x\): \[ x = 35 , \text{g} - 15 , \text{g} = 20 , \text{g} \]

Therefore, the mass of Product 2 is 20 g.
