1. Predicting Products of Chemical Reactions. Identify the type of reaction. Two elements: One compound: One compound, One element: Two compounds Hydrocarbon + O 2 Synthesis Decomposition Synthesis or Single replacement Synthesis or Double replacement Combustion

2. Combustion reaction The product is always!!!!!!!!! CO 2 + H 2 O

3. Double Replacement Switch the positive ions: Check Oxidation numbers: Examples: HOH + KCl  HCl + KOH Al 2 (SO 4 ) 3 + NH 4 ClO 3  (NH 4 ) 2 SO 4 + Al(ClO 3 ) 2

4. Practice these: 1. BaCl 2 + K 2 O 2. MgF 2 + Li 2 O 3. KI + Pb(NO 3 ) 2 4. FeS + HCl

5. Single Replacement Determine if the single element is positive or negative. Replace the same charged element in the compound. Examples: Al + Pb(NO 3 ) 2  Al(NO 3 ) 3 + Pb Mg + HCl  MgCl 2 + H 2

6. Practice these: 1. BaCl 2 + K 2. MgF 2 + O 2 3. K + Pb(NO 3 ) 2 4. FeS + Cl 2

7. Synthesis If there are only two elements: Combine them into a binary compound. Check oxidation number Examples: Rb + S  Rb 2 S Ba + S  BaS

8. Practice these: 1. H 2 + O 2 2. Mg + Cl 2 3. K + N 4. Ca + S

9. Synthesis If there are three or more elements: THERE WILL BE AT LEAST ONE POLYATOMIC ION. ARRANGE THE ELEMENTS INTO A COMMON POLYATOMOC ION. THE OTHER ION IS THE ELEMENT LEFT OVER. Examples: H 2 O + SO 2  H 2 SO 4 Ca + SO 2 + O 2  CaSO 4

10. Practice these: 1. NH 3 +H 2 O  2. H 2 SO 3 + O 2  3. CaO + SO 2  4. MgO + PO 3 

11. Decomposition: Products depends on the compound decomposing: Binary compounds simply break into individual elements: Examples: H 2 O  H 2 + O 2 MgCl 2  Mg + Cl 2

12. Practice these: 1. NH 3 2. SO 2 3. CaO 4. MgO

13. Hydroxides: Metal hydroxide + H 2 O Examples: NaOH  Na 2 O + H 2 O Ca(OH) 2  CaO + H 2 O

14. Practice these: 1. Al(OH) 3  2. LiOH  3. Fe(OH) 3  4. CuOH 

15. Carbonates: Metal oxide + CO 2 Examples: CaCO 3  CaO + CO 2 PbCO 3  PbO + CO 2

16. Practice these: 1. Li 2 CO 3  2. SrCO 3  3. Cu 2 CO 3  4. MgCO 3 

17. Chlorates Metal Chloride + O 2 Examples: Ba(ClO 3 ) 2  BaCl 2 + O 2 NaClO 3  NaCl + O 2 Fe(ClO 3 ) 3  FeCl 3 + O 2

18. Practice these: 1. LiClO 3  2. Sr(ClO 3 ) 2  3. CuClO 3  4. Mg(ClO 3 ) 2 
