- 2. -reaction in which precipitate is formed by the mixing of aqueous solution of two salts
- 4. - reactions in which a compound decomposes because of sunlight
- 9. -give me good reaction in which heat energy is absorbed
- 14. - in which two or more reactive combined to form a compound
- 15. - the chemical reactions in which are more reactive element displaces a less reactive element from a compound
Down
- 1. reactions in which ions are exchanged between 2 reactants forming new compounds
- 3. -give me the reaction in which both oxidation and reduction take place simultaneously
- 5. - reactions in which one compound decomposes in two or more compounds or elements
- 6. - addition of oxygen or non metallic element or removal of hydrogen or metallic element from a compound
