  1. 1. A substance that undergoes change during a chemical reaction.
  2. 6. A reaction in which one reactant is oxidized and another is reduced simultaneously.
  3. 7. A reaction in which a single reactant breaks down into simpler products.
  4. 9. The process in which a substance gains oxygen or loses hydrogen during a chemical reaction.
  5. 11. A new substance formed as the result of a chemical reaction.
  6. 13. A chemical reaction in which energy-heat- is absorbed from the surroundings.
  7. 14. A reaction in which two or more reactants combine to form a single product.
  8. 15. The oxidation of fats and oils in food, which causes them to become rancid – that is, to develop off-smells and tastes.

  1. 2. The chemical process by which metals are gradually degraded by reaction with substances like moisture or acids
  2. 3. A reaction in which two compounds exchange ions to form two new compounds.
  3. 4. A reaction in which an insoluble solid-precipitate-is formed when two aqueous solutions react.
  4. 5. A concise symbolic representation of a chemical reaction, showing reactants and products with their formulas.
  5. 8. A chemical reaction that releases heat to the surroundings as the products form.
  6. 10. A reaction in which a more reactive element displaces another from its compound
  7. 12. The process in which a substance loses oxygen or gains hydrogen during a chemical reaction.
