- 4. a process where one or more substances are transformed into new substances with different properties.
- 6. the smallest unit of a chemical element, possessing the element's chemical properties
- 8. a homogeneous mixture of two or more substances where the dissolved particles are evenly spread and too small to be seen or settle out.
- 9. a mixture that has particles ranging between 1 and 1000 nanometers in diameter, yet are still able to remain evenly distributed throughout the solution
- 11. a subatomic particle found within the nucleus of an atom, along with protons.
- 13. the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
- 16. a mixture where the components are not uniformly distributed and can be visually distinguished.
- 18. a substance formed when two or more different elements are chemically bonded together in a fixed ratio.
- 20. a type of mixture where the components are evenly distributed and appear uniform throughout, meaning the mixture has the same composition at every point
- 21. alters the appearance of matter but doesn't change its chemical composition.
- 22. a fundamental substance that cannot be broken down into simpler substances by ordinary chemical means.
