Question

Based on the Law of Conservation of Matter, describe the relationship between the mass of the reactants and the mass of the products.

A) The mass of the reactants equals the mass of the products.
B) The mass of the reactants is less than the mass of the products.
C) The mass of the reactants is greater than the mass of the products.
D) The mass of the products is always greater than the mass of the reactants.

Answer 1

The Law of Conservation of Matter states that the mass of the reactants equals the mass of the products.

Thus, your answer is A

Answer 2

Answer: The correct answer is Option A.

Step-by-step explanation:

Law of Conservation of Mass states that mass can neither be formed nor be destroyed but can be transformed from one form to another. Every balanced equation follows this law.

This law basically means that the total mass on the reactant side is always equal to the total mass on the product side.

For Example: The equation for the formation of water from hydrogen and oxygen gas, the reaction follows:

`2H_2+O_2\rightarrow 2H_2O`

Mass of hydrogen = 1 g/mol

Mass of oxygen = 18 g/mol

Total mass on the reactant side =
`[2(2* 1)+(2* 16)]=36g/mol`

Total mass on the product side =
`[2((2* 1)+16)]=36g/mol`

As, total mass on the reactant side is equal to the total mass on the product side. Hence, it is following Law of conservation of mass.

Therefore, the correct answer is Option A.
