10. Review: What is a single replacement reaction?
A free element reacts with a compound to form a new compound and to release one of the elements of the original compound
General Equation: AB + C  AC + B
Examples
2 HCl + Mg  MgCl2 + H2
2 KI + Cl2  2 KCl + I2

11. Two types of single replacement reactions
Metallic Free Non – Metallic Free
Free element is a metal
Most common
Example
Mg + 2HCl  MgCl2 + H2
Free element is a non-metal
Example
KI + Cl2  KCl + I2

12. Free elements will not always switch places… so how can we determine when a single replacement reaction will occur?

13. If the single replacement reaction is metallic free:
Use the activity series of metals
Anything higher on the list as a free element will replace anything lower on the list from a compound

14. Examples: Na + PbCl2  2 Na + PbCl2  2 NaCl + Pb
This reaction occurs because sodium is higher on the activity series than lead
Al + NaCl 
Al + NaCl  No Reaction
This reaction does not occur because aluminum is NOT higher on the activity series than sodium

15. If the single replacement reaction is non-metallic free:
Use the periodic table
Any free element higher in a family on the Periodic Table can replace any lower element from a compound.
Why does this work?

16. Examples Cl2 + NaI  Cl2 + 2 NaI  2 NaCl + I2
This reaction occurs because chlorine is higher in its family than iodine
S + H2O 
S + H2O  No Reaction
This reaction does not occur because sulfur is lower in its family than oxygen

17. Single Replacement Reaction Practice
Complete the practice at your desk. We will continue to work on the practice problems in class tomorrow.

18. Exit Ticket Explain why the reaction between has no reaction
NaF + Br2  No Reaction
