Q7P - Chemistry: Molecular Nature Of Matter And Change

Question

Can the relative amounts of the components of a mixture vary? Can the relative amounts of the components of a compound vary? Explain.

Step-by-Step Solution

Answer

In a mixture, the relative amounts of different components may vary while in a compound it cannot vary.

Step 1: Mixture

Mixtures are made by mixing two different components physically, so the relative amount of a mixture may vary.

That means in a mixture the amount of different components is not fixed.

Step 2: Compound

Compounds are formed by the chemical combination of two or more elements in specific ratios. As these are formed by reacting in a fixed ratio so the relative amount of the components cannot vary in a compound. Like when 2 atoms of Hydrogen and 1 atom of oxygen will combine, it will form water. If the ratio differs from 2:1 it won’t be the same compound as water.
