- It holds only one kind of particle
- It holds no particles of any kind
- It holds more than one kind of particle
- It holds particles of a fixed size
Show answer and solution
Correct answer: C. It holds more than one kind of particle
1. A pure substance has the same kind of particle all the way through.
2. Elements and compounds both fit that description, so both are pure substances.
3. A mixture always carries more than one kind of particle.
4. Because nothing is bonded in a mixture, its parts can be separated physically.
