Across
- 5. compounds that contain a certain amount of water within their crystalline structure.
- 6. a system for naming ionic compounds with cations that have more than 1 oxidation number (transition metals mostly).
- 8. a system used to name covalently bonded compounds, prefixes indicate the number of atoms of each element in the compound.
- 9. breaks down a single substance into 2 or more simpler substances: AB -> A + B
- 12. the substances that are produced by the reactions; usually on the left side of the equation or what the arrow points to.
- 13. an acid containing hydrogen and a nonmetal.
- 14. system of naming that follows a standardized set of rules.
- 16. an anion that contains oxygen and 1 other element.
- 17. a compound without water in its crystalline structure; used to describe a hydrate with water removed.
- 18. the substances that take part in the reaction; usually the right side of the equation or what the arrow points away from.
- 19. a solid that is formed out of solution during a chemical change.
Down
- 1. when a compound is burned in the presence of oxygen forming water and carbon dioxide.
- 2. is a model that uses chemical symbols, coefficients, and other symbols to represent a chemical reaction.
- 3. when 2 compounds or elements switch places: AB + CD -> AD + BC
- 4. combine 2 or more substances into a single product: A + B -> AB
- 7. a more reactive element replaces the less active element; one element switches places with another: AB + C -> AC + B
- 10. an acid contain more than 2 elements; namely hydrogen, oxygen, and at least on other nonmetal.
- 11. a compound made up of only 2 elements.
- 15. the number of electrons that an atom loses or gains when it bonds.
