| A | B |
|---|
| synthesis | 2 elements of opposite charge react to form a compound |
| decomposition | a compound is broken down into simpler substances |
| single replacement | an strong element replaces a weaker element ( with the same charge) from a compound to form a new compound and isolate a new element |
| double replacement | 2 ionic compounds react to form 2 new compounds |
| activity series | shows "strength" of elements |
| catalyst | helps a reaction take place |
| endothermic | heat is absorbed by the reaction |
| exothermic | heat is reloeased by the reaction |
| reactant | substance that enters into a chemical reaction |
| product | what is formed in a chemical reaction |
| chemical equation | consise representation of a chemical reaction |
| skeleton equation | shows formulas is not balanced |
| balanced equation | same number and kind of elements of each side of reaction- verifies law of conservation of matter |
| activity series | used for singel replacement reactions to determine if a reaction can occur |
| law of conservation of matter | matter is not created or destroyed in chemical reactions |
| law of conservation of energy | energy is not created or destroyed in chemical reactions |
| decomposition of carbonates | produces an oxide and carbon dioxide |
| decomposition of acids | produces an oxide and water |
| decomposition of hydroxides | produces an oxide and water |
| decomposition of chlorates | produces a chloride and oxygen |
