Across
- 2. the energy stored in the chemical bonds of a substance
- 7. a reaction in which one element takes the place of another element in a compound (A + BC --> AC + B)
- 11. a reaction in which two different compounds exchange positive ions and form 2 new compounds (AB + CD --> AD + BC)
- 12. a substance that affects the reaction rate without being used in the reaction
- 13. The substances that change in a chemical reaction (the starting materials of a reaction)
- 14. the numbers that appear before a formula in a chemical equation to show the relative proportions of each reactant to the product
- 16. a chemical reaction that releases energy into its surroundings
Down
- 1. a reaction in which a compound breaks down into two or more simpler substances (AB --> A + B)
- 3. a state in which the forward and reverse paths of change take place at the same rate
- 4. a reaction in which a substance reacts rapidly with oxygen, often producing heat and light
- 5. a reaction in which the conversion of reactants into products and the conversion of products into reactants can happen simultaneously
- 6. a reaction in which electrons are transferred from one reactant to another
- 8. A representation of a chemical reaction in which reactants and products are expressed as formulas
- 9. a reaction in which 2 or more substances react to form a single substance (A + B --> AB)
