Balancing Reactions

• Choose the largest compound
• Make its coefficient 1
• Choose any element in that compound that appears
  in only 1 other location

4

• Balance that element with coefficients where that
  element appears
• Repeat until all elements are balanced
• Double if on half-unit

Types of Reactions
13

• Single Displacement
• Double displacement
• Synthesis
• Decomposition
• Combustion

14
Single Displacement

• A Metal or hydrogen replaces the positive portion
  of a compound or a nonmetal does it for the
  negative portion

15

• _ CaBr2(aq) _ F2(g)
• ?
• _ CaF2(aq) _ Br2(g)

16
Double Displacement

• Two compounds exchange negative portions
• Change of phase a must

17
Double Displacement

• __ Ca(NO3)2 __ K2SO4
• __ CaSO4 __ KNO3

18
Synthesis

• Smaller molecules or elements combine to make
  larger molecules

19
Synthesis

• _CaO _CO2
• ?
• _CaCO3

20
Decomposition

• Larger molecules break down to form smaller
  molecules or elements

21
Decomposition

• ?
• _MgO _CO2

22
Combustion

• A carbon compound is combined rapidly with oxygen
  producing carbon dioxide water
