8. Review Double and Single Replacement Reactions
What questions do you have about the topics? Are there any problems you would like to review?

9. Double Replacement Practice
Take out the worksheet and lets look at some problems. Mr. Klotz will grade it for accuracy.

10. Predicting Products of Synthesis and Decomposition Reactions

11. Synthesis Reactions
Elements or simple compounds are combined to form ONE product
Combine elements and criss-cross the charges
Examples
Cu(II) + S  CuS
4 Na + O2  2 Na2O

12. Decomposition Reactions
If TWO elements (binary compound) are present in the original compound, just break it apart into two elements
2 HCl  H2 + Cl2

13. Decomposition Reactions
If THREE elements (ternary compound) are present, determine if one of them is a HALOGEN
If one element is a halogen, then the halogen and the metal stick together and oxygen gas is produced
2 KClO3  2 KCl + 3 O2

14. Decomposition Reactions
If there are no halogens present, then a metallic oxide and a gas with 1 less oxygen than the polyatomic ion is produced
CaCO3  CaO + CO2

15. Predicting Products Practice
Complete the practice at your desk. Whatever you do not finish will become your HW.
