ok here they are:
1. How are atoms different from molecules?
2. If you mix salt, sand, and sugar with water in a small jar, will the result be a suspension, a solution, or both?

ok for #1 i have no idea and for #2 i think it's both because a suspension is a solution but a solution is not a suspension and because it's spread out evenly by a liquid
but i'm not sure if the the particles will sink

please and thank you ^ ^
