Question

Expert Solution

Step 1

(a) Any mixture is said to be homogeneous when the proportion of its components is uniform throughout a sample .

Since the different gases in air has an uniform proportion air is a homogeneous mixture .

(b) A compound is a chemical combination of two or elements .Since water is formed from hydrogen and oxygen water is a compound

(c)Diamond is an allotrope of the element carbon. Therefore diamond is an element.

(d)Soil has different components in different proportion .Hence soil is heterogeneous mixture.
