12. 20% 13. a. 3 particles (2 sodium and 1 sulfate) b. 1 particle (molecular/covalent)

14. a. sodium sulfate (3 particles will be produced) 15. 66.1g 16. 300.g/mol 17. 16.6g

18. Solubility: maximum amount of solute that will dissolve in a given amount of solvent at a given temperature. 19. increase temperature 20. to increase solubility of gases decrease the temperature and increase the pressure 21. increase the temperature, increase stirring, decrease the size of the particles (larger surface area) 22. look up in notes or book 23. look up in notes or book 24. Physical!!!! The same chemicals are present before and after the change! TAKS 1. B 2. A 3. C 4. B 5. A
