2 Net Ionic Equations Double Replacement Redox / Single Replacement Synthesis/Decomposition Complex Ions Combustion

3 Identification of Double Replacement Reaction Acid / Base Acid / Base NH 3 + HF NH F – NH 3 + HF NH F – Precipitation Precipitation Ba 2+ + SO 4 2- BaSO 4 Ba 2+ + SO 4 2- BaSO 4 Both Both H + + HSO Ca OH - CaSO H 2 O H + + HSO Ca OH - CaSO H 2 O

4 Redox and Single Replacement Redox Redox Use of key terms Use of key terms MnO 4 - H 2 O 2 Cr 2 O 7 2- HNO 3 MnO 4 - H 2 O 2 Cr 2 O 7 2- HNO 3 Metals with multiple oxidation states Metals with multiple oxidation states Sn 2+ Sn 4+ Cr 2+ Cr 3+ Cr 6+ Sn 2+ Sn 4+ Cr 2+ Cr 3+ Cr 6+ Acidic and Basic conditions Acidic and Basic conditions 2 MnO H H 2 O 2 2 Mn O H 2 O 2 MnO H H 2 O 2 2 Mn O H 2 O

5 Redox / Single Replacement Single Replacement Single Replacement Like will replace like Like will replace like 2 Na + 2 H 2 O 2 Na OH - + H 2 Cl I - 2 Cl - + I 2 Cl I - 2 Cl - + I 2

6 Combustion Reaction of a compound with oxygen gas to produce oxides of all elements in the compound Reaction of a compound with oxygen gas to produce oxides of all elements in the compound C 3 H O 2 3 CO H 2 O C 3 H O 2 3 CO H 2 O CH 3 CH 2 OH + 3 O 2 2 CO H 2 O CH 3 CH 2 OH + 3 O 2 2 CO H 2 O 4 CH 3 NH O 2 4 CO H 2 O + 4 NO 2 4 CH 3 NH O 2 4 CO H 2 O + 4 NO 2

7 Decomposition/Synthesis Decomposition has only one reactant and it breaks up into elements and /or compounds Decomposition has only one reactant and it breaks up into elements and /or compounds MgCO 3 MgO + CO 2 MgCO 3 MgO + CO 2 Ba(OH) 2 BaO + H 2 O Ba(OH) 2 BaO + H 2 O 2 Al 2 O 3 4 Al + 3 O 2 2 Al 2 O 3 4 Al + 3 O 2

8 Decomposition / Synthesis Composition has two reactants that combine into one product Composition has two reactants that combine into one product S O 2 8 SO 2 S O 2 8 SO 2 nonmetal oxides plus water make acids nonmetal oxides plus water make acids SO 3 + H 2 O H + + HSO 4 - SO 3 + H 2 O H + + HSO 4 - metal oxides plus water makes metal hydroxide metal oxides plus water makes metal hydroxide CaO + H 2 O Ca OH - CaO + H 2 O Ca OH -

9 Complex Ions Particles that generally combine with ammonia or hydroxide to form complex ions with a charge Particles that generally combine with ammonia or hydroxide to form complex ions with a charge AgCl + 2 NH 3 Ag(NH 3 ) Cl - AgCl + 2 NH 3 Ag(NH 3 ) Cl - Cu NH 3 Cu(NH 3 ) 4 2+ Cu NH 3 Cu(NH 3 ) 4 2+ Al OH - Al(OH) 4 - Al OH - Al(OH) 4 - having the correct ligand number is not required but being consistent with number and charge is important having the correct ligand number is not required but being consistent with number and charge is important

10 In Review Identify type of reaction Identify type of reaction Equations MUST be balanced Equations MUST be balanced Check for appropriate charges Check for appropriate charges Remember not to include spectator ions Remember not to include spectator ions
