Across
- 4. a type of decomposition reaction in which the reactant will break down just by the absorption of the photons
- 5. a compound breaks down when heated.
- 7. an atom or group of atoms that carries a positive or negative electric charge as a result of having lost or gained one or more electrons
- 9. a natural process that converts a refined metal into a more chemically stable oxide
- 10. reaction in which a compound breaks down into two or more simpler substances.
- 11. a chemical reaction occurring in an aqueous solution where two ionic bonds combine, resulting in the formation of an insoluble salt
- 13. A displacement reaction occurs when a more reactive element displaces, or pushes out, a less reactive element from a compound that contains the less reactive element.
Down
- 1. when an acid and a base react to form water and a salt
- 2. reaction in which energy is released in the form of light or heat.
- 3. Double displacement reactions are those in which two chemical substances react by exchanging ions to produce two new molecules
- 6. aerial oxidation of unsaturated fat present in food gives it an unpleasant flavor and odor.
- 8. type of chemical reaction that involves a transfer of electrons between two species.
- 9. reaction in which two or more substances combine to form a single new substance.
- 12. When electricity is passed through a molten compound which is ionic nature, then the ions of the compound separate into components decomposing the compound
- 14. reactants absorb heat energy from the surroundings to form products.
