Question

Using examples, how can you look at a substance and determine if it is a pure substance or a mixture?

Answer 1

A pure substance is something that is not mixed with anything like like a jar of rice or a jar of marbles
A mixture is something that is mixed together like if you made lemonade and you mixed lemon juice and water and sugar together it's a mixture and another example is if you mix sand and rocks together it's a mixture I hope I helped you
