Guide questions
1. Pure substance, because the molecules contains the same components as the other molecules nearby.
2. Mixture, because as you can see they don't have the same molecular structure they have different components thus making it a mixture.
3. I can classify it by looking at the colours and sizes, different colours/sizes means different elements, after that I can determine if it's Pure substance or a Mixture.
Glad I could help!
