Question

Describe the mass of the reactants and products given the balanced chemical reaction.

A) The mass of the products is 2/3 that of the reactants.
B) The mass of the reactants equals the mass of the products.
C) The mass of the reactants is less than the mass of the products.
D) The mass of the reactants is greater than the mass of the products.

Answer 1

B) The mass of the reactants equals the mass of the products.

Step-by-step explanation:

In any balanced chemical reaction, it is known by default that the mass of the products and reactants must always be the same.

This is according to the law of conservation of mass.

• Every chemical reactions obey the law of conservation of mass.
• The law states that "In every chemical reaction, matter is neither created nor destroyed but changed from one form to another".
• In essence, there is no mass loss in a chemical reaction.
• This law is usually shown by the balancing of chemical species on both sides of the equation.
