Question

how is law of conservation of matter verified in the experiment of calcium chloride and
sodium sulphate

Answer 1

when calcium chloride and Sodium sulphate react, they form equal amount of sodium chloride and calcium sulphate. Hence the law of conservation of matter is verified

Answer 2

Answer: The law of conservation of mass is verified below.

Explanation:

Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transferred from one form to another form. In a chemical reaction, total mass on the reactant side is equal to the total mass on the product side.

All the balanced chemical equations follow this law.

For the reaction of calcium chloride and sodium sulfate, the balanced chemical equation follows:

$CaCl_2+Na_2SO_4\rightarrow CaSO_4+2NaCl$

On reactant side:

Total mass = $[(40+(2\times 35.5))+((2\times 23)+32+(4\times 16))]=253g/mol$

On product side:

Total mass = $[(40+32+(4\times 16))+2(23+35.5)]=253g/mol$

As, the total mass on the reactant side is equal to the total mass on the product side. Thus, this chemical equation follows Law of conservation of mass.

Hence, the law is verified.
