Conservation in Chemical Reactions Quick Check
Science 8 Q1 / Matter Interactions
In a chemical reaction, two molecules with a total mass of 76 amu react to form a single molecule. What is the mass of the molecule that is formed?(1 point)
Responses
38 amu
152 amu
76 amu
228 amu
76 amu
To find the mass of the molecule that is formed in the chemical reaction, you need to consider the law of conservation of mass. This law states that mass is neither created nor destroyed in a chemical reaction, so the total mass of the reactants should be equal to the total mass of the products.
Given that the two reacting molecules have a total mass of 76 amu, and they react to form a single molecule, the mass of the molecule that is formed should also be 76 amu.
Therefore, the correct answer is 76 amu.
