Question

State the law of conservation of mass give one example of illustrate in this mass

Answer 1

Explanation:

Statement:

Law of conservation of mass states that mass in a chemical reaction mass is neither created nor destroyed.

• The carbon atom changes from solid to gas but its mass remain unchanged.
• When wood burns we get soot, ashes, and gases their total mass will be equal to the original mass of the charcoal when it first reacted with the oxygen.  

Answer 2

Answer:

For example:  100gm of calcium carbonate decomposes to produce 56gm of calcium oxide and 44gm of carbon dioxide.

Mass of the reactants = 100gm

Mass of the products = 56gm + 44gm = 100gm

Here, the mass of the product and the mass of reactant are equal. Therefore, there is no change in the given chemical reaction.
