Across
- 4. characteristics of matter that can only be observed when one substance changes into a different substance, such as iron to rust.
- 6. when the solute breaks up from a larger crystal of molecules into much smaller groups or individual molecules.
- 11. the substances formed from chemical reactions.
- 13. a mixture in which particles are dispersed throughout the bulk of a fluid.
- 16. a mixture consisting of parts that are all the same, or evenly mixed. A solution is a type of homogenous mixture.
- 17. a substance that takes part in and undergoes change during a reaction.
- 19. when particles of different substances mix together naturally.
- 20. a reaction that occurs when heat is absorbed by the system from the surroundings.
- 21. a reaction that occurs when heat is released by the system into the surroundings.
Down
- 1. a law that states that matter is not destroyed or created, therefore the reactants will have the same mass as the products.
- 2. a number placed before the molecule that tells you how many molecules are in the equation.
- 3. the major component in solution, able to dissolve other substances.
- 5. contains different substances that are not chemically joined to each other.
- 7. a small number placed after an element that shows how many atoms are in the molecule.
- 8. a mixture that has different parts, not evenly mixed.
- 9. a liquid mixture in which the minor component (the solute) is uniformly distributed within the major component (the solvent).
- 10. when matter changes from one state to another.
- 12. Formula identifies the number and type of each type of atom in a molecule.
- 14. the minor component in a solution, dissolved in the solvent.
- 15. a system of chemical changes that involves the breaking and reforming of chemical bonds to create new substances.
- 18. characteristics of matter that can be seen through direct observation such as density, melting point, and boiling point.
