Chemistry
1 answer:
kicyunya [14]3 years ago
4 0

Answer:

Look in explanation:

Explanation:

Chalk is composed of Ca(CO3).

This will not dissolve in H2O because the ionic bonds between the calcium and carbonate are too powerful to be disrupted by water so it will have no effect.

No reaction takes place when sand is mixed with water and the sand would just sink down.
