- 6. Oxygen combines with a compound to form carbon dioxide and water.These reactions are exothermic, meaning they give off heat
- 8. One element takes place with another element in the compound.
- 9. Two solutions of soluble salts are mixed resulting in an insoluble solid (precipitate) forming
- 10. Two or more compounds combine to form one compound
Down
- 1. in which two chemical substances react by exchanging ions to produce two new molecules
- 2. The opposite of a combination reaction – a complex molecule breaks down to make simpler ones
- 3. An acid and a base react with each other. Generally, the product of this reaction is salt and water
- 4. a type of reaction in which multiple reactants combine to form a single product
- 5. reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat
- 7. is a type of chemical reaction that occurs between an acid (H+) and a base (OH-). In this reaction, the acid and base react with each other to produce a salt and water
