  10. 13. The name of a liquid that has a solvent and a solute
  11. 14. A reaction where an insoluble solid form from two liquids
  12. 15. When heat is used to break apart a substance and create new substances
  13. 17. A word to describe something that can dissolve in a liquid
  14. 18. When a substance reacts with oxygen like rust forming on iron
