Across
- 6. a chemcial reaction that gives away a material but doesn't receive a material back
- 7. how quickly the concentration of reactants decreases and how quickly the concentration of products increases.
- 9. reaction having a net absorption of energy
- 10. the amount of energy required to pull two bonded atoms apart, which is the same amount of energy released when they are brought together.
- 11. a chemcial reaction that occurs when compounds trade elements or gives away an element and gets a new one back
- 12. a chemical reaction that releases large amounts of energy and creates oxides. It requires oxygen.
Down
- 1. one or more new compounds are formed as a result of the rearrangement of atoms
- 2. reaction having a net release of energy
- 3. no atoms are gained or lost during any reaction. Instead, atoms simply change partners to form new materials
- 4. the minimum energy required to overcome the inital breaking of bonds in reactants.
- 5. a chemical reaction that builds a bigger compound from simpler materials
- 8. a chemical reaction that breaks down a compound
