Question

what happens when chalk powder and sand are added to water ? why?​

Answer 1

Answer:

The chalk will also mostly settle out but the finer grains may stay in suspension - prevented from falling to the bottom by random collisions with the water molecules. A tiny proportion of the chalk will dissolve and another tiny proportion may react with dissolved carbon dioxide (in the form of carbonic acid).

please mark me as the brainliest :)
