Question

copper oxide obtained by heating copper carbonate contains copper and oxygen in the same ratio by mass. which law is stated

Open in App

Solution

CuCO₃ $\to$ CuO + CO₂
This is 'LAW OF DEFINITE PROPORTIONS" . This explains that the composition of element in a compound is always in same ratio by mass and is independent from source of preparation.
