1. Types of Reactions Notes/Demos

2. Objective:
Today I will be able to:
Differentiate between the 5 types of reactions
Evaluation/Assessment:
Informal assessment – listening to student interactions during the assessment/ demonstrations and as they complete the types of reactions practice
Formal assessment – analyzing student responses to the types of reactions practice and exit ticket.
Common Core Connection
Build Strong Content Knowledge
Make sense of problem and persevere in solving them
Look for and express regularity in repeated reasoning

3. Lesson Sequence Evaluate: Warm – Up
Engage/Explore: Types of Reactions Analogy
Engage and Explain: Types of Reactions Demos/Assessment
Elaborate: Types of reactions practice
Evaluate: Exit Ticket

4. Warm - Up Identify the type of reaction and balance
Ca(OH)2 + Al2(SO4)3  CaSO4 + Al(OH)3
Mg + Fe2O3  Fe + MgO

5. Objective Today I will be able to:
Differentiate between the five types of reactions.

6. Homework
Finish Identifying Types of Reactions Practice

7. Agenda Warm – Up Types of Reactions Analogy
Types of Reactions Demos/Assessment
Identifying Types of Reactions Practice
Exit Ticket

8. Types of Reactions Analogy
Working with your row, create an analogy for the 5 types of reactions (5 minutes). We will share ideas as a class.

9. Types of Reactions Demos/Assessment

10. Directions Work in partners Each group needs a whiteboard
Ms. Ose will put a question/reaction or statement on the board and you will respond with the correct type of reaction
If your answer is correct, you get a point

11. Types of Reactions Assessment

12. A + B  AB

13. Synthesis

14. A free element reacts with a compound to form a new compound and to release one of the elements of the original compound

15. Single Replacement (Double Displacement)

16. Demo!
C3H7OH(l) + O2(g)  CO2(g) + H2O(g), triangle above arrow

17. Combustion

18. 3 CaCl2 + 2 AlN  2 AlCl3 + Ca3N2

19. Double Replacement

20. Demo!
CuSO4 + 2 NaOH  Cu(OH)2 + Na2SO4

21. Double Replacement

22. CaCO3  CaO + CO2

23. Decomposition

24. Elements or simple compounds are combined to form ONE product

25. Synthesis

26. Occurs when a hydrocarbon combines with oxygen gas in the air – burning

27. Combustion

28. 2 KI + Cl2  2 KCl + I2

29. Single Replacement

30. Demo!
Mg (s) + O2(g)  MgO (s), triangle above arrow

31. Synthesis

32. Two ionic compounds react to form two new ionic compounds; “switching partners”
AB + CD  AC + BD

33. Double Replacement (Double Displacement)

34. AB + C  AC + B

35. Single Replacement

36. ONE compound breaks down into simpler substances
General Equation: AB  A + B

37. Decomposition

38. Demo! H2O2(aq)  H2O(g) + O2(g), KI above the arrow
Gummy Bear Decomposition

39. Decomposition

40. Demo!
Mg(s) + HCl(aq)  H2(g) + MgCl2(aq)

41. Types of Reactions Practice
Using your notes balance the equation and then predict the type of reaction that the equation represents.

42. Exit Ticket Identify the type of reaction:
C10H O2 ---> 10 CO2 + 4 H2O
Mg + 2 H2O ---> Mg(OH)2 + H2
2 H2O ---> 2 H2 + O2
8 Fe + S8 ---> 8 FeS
Pb(NO3)2 + 2 KI ---> PbI2 + 2 KNO3
