3. Chemical Reactions
Unit 2 Lesson 8

4. What are chemical reactions?

5. Writing Chemical Reactions
Reactants  Products
Synthesis
Decomposition
Single Replacement
Double Replacement
Polymerization
Condensation Polymerization

6. Synthesis Reaction
A + B  AB

7. Synthesis Reaction
Example: making water
2 H2 + O2  2 H2O

8. Decomposition Reaction
AB  A + B

9. Decomposition Reaction
Example – bubbling soda
H2CO3  H2O + CO2

10. Single Replacement Reaction
A + BC  AB + C

11. Single Replacement Reaction
Example:
Na + LiCl  NaCl + Li

12. Double Replacement
AB + CD  AD + CB

13. Double Replacement
Example – Mixing up ionic compounds
NaCl + AgNO3  NaNO3 + AgCl

14. Acid-Base Reaction
A + H+ AH+
AH A- + H+

15. Acid-Base Reaction

16. Polymerization Reaction
n(Monomer)  Polymer
A + A + A + A + A …. AAAAA

17. Polymerization Reaction

18. Polymerization Reaction

19. Polymerization Reaction: PVC

20. Condensation Polymerization Reaction
n(Monomer)  Polymer + H2O
A + A + A…. AAA + H2O
