$\begin{array}{cccc}& \text{Column - I}& & \text{Column - II}\\ \text{a.}& \text{A chalk water}& 1& \text{A gaseous}\\ & \text{mixture}& & \text{mixture}\\ \text{b.}& \text{A glucose}& 2& \text{A heterogeneous}\\ & \text{solution}& & \text{solid-liquid mixture}\\ \text{c.}& \text{Carbonated}& 3& \text{A homogeneous}\\ & \text{water}& & \text{solid-liquid mixture}\\ \text{d.}& \text{Air}& 4.& \text{A gas-liquid mixture}\end{array}$

• A. a - 2, b - 3, c - 4, d - 1
• B. a - 1, b - 4, c - 2, d - 3
• C. a - 2, b - 4, c - 3, d - 1
• D. a - 2, b - 4, c - 1, d - 3

Answer 1

The correct option is A

a - 2, b - 3, c - 4, d - 1

A chalk water mixture is a heterogeneous solid-liquid mixture as the solid (chalk) is non-uniformly dissolved (mixed) in water. Moreover, the particles are easily visible.
A glucose solution is a homogeneous solid-liquid mixture as the solid (glucose) is uniformly dissolved (mixed) in water.
Carbonated water is a gas-liquid mixture. It is a homogeneous solution as the components in the mixture are uniformly distributed throughout the mixture.
Air is a gaseous mixture. It is a mixture of various gases such as nitrogen, oxygen, carbon dioxide, argon, water vapour, etc.
