Unit 8: Reactions

1. A redox reaction in which a compound breaks up to form two products
4. A molecule with asymmetrical electron distribution resulting in partially charged ends.
6. The gain of electron(s), causing the oxidation number of a species to become more negative.
7. A solution reaction in which the positive ion of one compound combines with the negative ion of the other compound to form a precipitate, and the other ions remain dissolved in solution.
10. Energy cannot be created or destroyed by physical or chemical change.
13. An ion that does not participate in the chemical reaction.
15. The substances that are reacted together, designated as the left side of the chemical reaction.
16. Matter cannot be created or destroyed by physical or chemical change.
17. A redox reaction in which two elements combine to form a compound.
18. A number placed in front of a formula to balance a chemical reaction.

2. An insoluble solid that is formed either in a double-replacement reaction or as an excess solute added to a saturated solution.
3. The whole-number ratio between components of a balanced, chemical reaction.
4. The substances that are formed by a chemical reaction, designated as the right side of the chemical equation.
5. The mathematics of mole relationships.
8. Charge cannot be created or destroyed by physical or chemical change.
9. A reaction in which one element is oxidized and another element is reduced.
11. A chemical change where reactants are turned into products.
12. The loss of electron(s), causing the oxidation number of a species to become more positive.
14. A redox reaction in which an element replaces an ion in a compound.
