Predicting Products

• Predict products based on pattern and oxidation
  numbers (charges) in a skeleton equation
• Balance skeleton equation

3
Single Displacement

• Hints always pair positive and negative ions
• Examples Silver and Hydrochloric Acid
• Bromine and Magnesium fluoride

4
Synthesis

• Hints always write ion first
• - ion last
• Patterns
• 1) two or more elements combine
• Fe and S forms Iron (II) sulfide
• 2) nonmetallic oxide and water forms acid
  Sulfur dioxide and water forms sulfurous acid

5
Synthesis cont.

• 3) Metallic oxide and water forms a hydroxide
• Sodium oxide and water forms sodium hydroxide
• 4) nonmetallic oxide and metallic oxide forms a
  salt
• Carbon dioxide and sodium oxide forms sodium
  carbonate

6
Double Displacement

• Hint when switching partners always place
  and _ ions together
• Never two
• Never two
• Example
• Vanadium (V) carbonate and silver phosphate forms
  Vanadium (V) phosphate and silver carbonate

7
Combustion

• Always hydrocarbon and oxygen forming carbon
  dioxide and water

8
Decomposition

• Patterns
• 1) acids form water and element oxide
• Example
• 2) metallic hydroxides form metallic oxide and
  water
• Example

9
Decomposition cont.

• 3) metallic carbonates form metallic oxide and
  carbon dioxide
• Example
• 4) metallic chlorates form metallic chlorides and
  oxygen
• Example
• 5) Binary compounds form separate elements
