Question

100g caco3 decomposes to give 56g of cao and 44g of co2 .Which law of chemichal combination is illustrated here .State the law

Answer 1

Answer:

The given reaction depicts the law of conservation of mass.

It is because as we can observe from the given data, the mass of the reactants and products is same.

Explanation:

The law of conservation of mass states that mass present in an isolated system can neither be created nor destroyed in a given chemical reaction.

Here, in the given decomposition reaction, the reactant is CaCo3 which is 100g in mass.

The products produced are: CaO( mass is 56g) and Co2( 44g). Now, adding both the masses of the products, we get 100g.

Hence, it has been proved that the mass remains constant in any chemical reaction.

Answer 2

Answer:

The law of chemical combination of the reaction is illustrated here is "Law of Conservation of Mass".

Explanation:

• The following chemical reaction follows the "law of conservation of mass". This law is given by Antoine Lavoisier in 1789 which states that “Matter cannot be created or destroyed in any chemical reaction”.
• 100g $\mathrm{CaCO}_{3}$ decomposes to give 56g CaO and 44g  $c o_{2}$ but the reactant and product mass weight is the same even the molecules get changed or divided.
• The atoms of the reactants are ordered to form a new element but none of the atoms get destroyed or formed in the whole chemical procedure.
