Question

conservation of matter
compare the box on the left containing the reactants in a chemical reaction. which box on the right is the correctly represents the products according to the law of conservation of mass?
based on the law of conservation of matter, describe the relationship between the mass of the reactants and the mass of the products.
the mass of the reactants equals the mass of the products.
the mass of the reactants is less than the mass

Explanation:

Step1: Count atoms in reactant box

Count each type of atom (represented by different - colored balls) in the left - hand box (reactants).

Step2: Count atoms in each product box

• Box A: Count the number of each type of atom. The number of atoms of each type is the same as in the reactant box.
• Box B: The number of atoms is less than in the reactant box.
• Box C: The number of atoms is more than in the reactant box.
• Box D: The number of atoms is different from the reactant box.

According to the Law of Conservation of Mass, the number of atoms of each element must be the same in reactants and products.

For the second part, based on the Law of Conservation of Matter (Mass), in a chemical reaction, matter is neither created nor destroyed.

Answer:

For the first question: A.
For the second question: A. The mass of the reactants equals the mass of the products.
