Verified Answer
4.88 g of KClO3 when heated, produces 1.92 g of O2 and 2.96 g of KCl. ...
2KClO3→2KCl+3O2
Mass of the reactant = total mass of the products (2.96+1.92=4.88 g)
According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants. Therefore it is the law of conservation of mass.

4.88 g of KClO3 when heated, produces 1.92 g of O2 and 2.96 g of KCl. ...
The correct answer is option 'A' - The result illustrates the law of conservation of mass.
Explanation:
The law of conservation of mass states that in a chemical reaction, the total mass of the reactants is equal to the total mass of the products. This means that matter cannot be created or destroyed during a chemical reaction, only rearranged.
In this experiment, potassium chlorate (KClO3) is heated, resulting in the production of oxygen gas (O2) and potassium chloride (KCl). The given masses are as follows:
- Mass of KClO3 = 4.88 g
- Mass of O2 produced = 1.92 g
- Mass of KCl produced = 2.96 g
To determine if the law of conservation of mass is satisfied, we need to compare the total mass of the reactants (KClO3) with the total mass of the products (O2 + KCl).
Total mass of reactant (KClO3) = 4.88 g
Total mass of products (O2 + KCl) = 1.92 g + 2.96 g = 4.88 g
Since the total mass of the reactants is equal to the total mass of the products, the result satisfies the law of conservation of mass. This means that the mass of the reactants is conserved and is equal to the mass of the products.
Therefore, option 'A' is the correct answer as the result of the experiment illustrates the law of conservation of mass.

- Mass of KCl produced = 2.96 g
To determine if the law of conservation of mass is satisfied, we need to compare the total mass of the reactants (KClO3) with the total mass of the products (O2 + KCl).
Total mass of reactant (KClO3) = 4.88 g
Total mass of products (O2 + KCl) = 1.92 g + 2.96 g = 4.88 g
Since the total mass of the reactants is equal to the total mass of the products, the result satisfies the law of conservation of mass. This means that the mass of the reactants is conserved and is equal to the mass of the products.
Therefore, option 'A' is the correct answer as the result of the experiment illustrates the law of conservation of mass.
