Answer 1

On dissolving chalk powder in water, a suspension is obtained . we can say that the the mixture so obtained is a suspension as if we pass light rays from the beaker , they will be scattered until the suspension breaks. Also the particle size of the mixture would be larger i.e. 10^-5 micrometer. we will also I serve that the solution obtained will be heterogenous and opaque.And if the mixture is filtered , than the residue will be left on the filter paper.Through these observations we can conclude that the mixture obtained is a suspension
