1. Types of Reactions!!

2. Five Types of Reactions
Synthesis
Decomposition
Single Displacement
Double Displacement
Combustion

3. One Product A + B  AB 2H2 + O2  2H2O Synthesis General Formula:
Example:
2H O2  2H2O
One Product

4. Complete & Balance the following reactions:
K Cl2 →
Al O →

5. Complete & Balance the following reactions:
2K Cl2 → 2KCl
4Al O → 2Al2O3

6. One Reactant AB  A + B 2NaClO3  2NaCl + 3O2 Decomposition
General Formula:
AB  A B
Some Examples:
2NaClO3  2NaCl O2
One Reactant

7. Complete and balance the following reactions:
Ca3N2 →
Rb2O →

8. Complete and balance the following reactions:
Ca3N2 → 3Ca + N2
2Rb2O → 4Rb +O2

9. A + XY  X + AY B + XY  Y + XB Single Displacement OR
General Formula:
A XY  X AY
If A is a metal, switch with X OR
B XY  Y XB
If B is a nonmetal, switch with Y

10. NOTE: A more reactive element can replace a less reactive element, not vice-versa.

12. Use the Activity Series:
Most reactive metals and halogens are at top of chart and can replace anything underneath.
Example:
Cu AgNO3  2Ag Cu(NO3)2

13. Complete and balance the following single-replacement reactions: (Use your activity series):
Na Cu(NO3)2 →
Al Li3N →
Cl LiBr2 →

14. Complete and balance the following single-replacement reactions: (Use your activity series):
2Na Cu(NO3)2 → 2NaNO3 + Cu
Al Li3N → NO REACTION
Cl LiBr2 → 2LiCl + 2Br2

15. Double Displacement
General Formula:
AB XY  XB AY

16. 3 Types of Products Formed:
Double Displacement
3 Types of Products Formed:
Precipitate (solid)
Water
Gas
* Use a solubility table to see which product forms a solid!

17. NaCl + AgNO3  AgCl (s) + NaNO3
Ex:
NaCl + AgNO3  AgCl (s) + NaNO3

18. Complete and balance the following double-replacement reactions:
HCl KOH →
Ba(NO3) Na2SO4 →

19. Complete and balance the following double-replacement reactions:
HCl KOH → H2O + KCl
Ba(NO3)2 +Na2SO4 → BaSO4 + 2NaNO3

20. Fuel (C&H) + O2  CO2 + H2O C3H8 + 5O2  3CO2 + 4H2O Combustion
General Formula:
Fuel (C&H) + O2  CO H2O
Example:
