b.Copper ore contains Copper carbonate.
In the first stage of the extraction process, the Copper carbonate is decomposed
by heating to form Copper oxide and Carbon dioxide.
CuCoz CuO + CO2
When 100 g of copper carbonate is decomposed completely in this way, it is found
that the total mass of products is 100 g.
Give reason why the starting mass of copper carbonate is the same as the mass of
the products formed. Justify.

Answer 1

Answer:

this is because as mass of all the reactant on the left side is equal to the mass of product on the right side.

Explanation:

This is because every chemical reaction justify the 'law of conservation of mass ' which states that mass of reactants = mass of product during any chemical reaction

hope it helps you!!!!!
