Types of Chemical Reactions
2
Combination/Synthesis Reaction

• General Equation
• R S ? RS
• Reactants Generally two elements or two
  compounds.
• Probable Products A single compound
• Example
• 2Mg(s) O2(g) ? 2MgO(s)
• Practice problems pg 214 13-14

3
Decomposition

• General Equation
• RS ? R S
• Reactants Generally a single binary or ternary
  compound
• Probable Products Two or more elements
• Example
• 2H2O(l) ? 2H2(g) O2(g)
• Practice problems pg 216 15-16

4
Combustion

• General Equation
• fuel O2 ? CO2 H2O
• Reactants A compound of C, H, (O) and oxygen
• Probable Products Carbon dioxide and water
• Example
• 2C3H8O(g) 9O2(g) ? 6CO2(g) 8H2O(l)
• Practice problems pg 221 20-21

5
Single Displacement

• General Equation
• R TS ? RS T
• Reactants An element and a compound. For
  displacement to occur, the element that is
  displaced must be less active than the element
  that is doing the displacing.
• Probable Products A different element and a new
  compound
• Example
• Zn(s) 2HCl(l) ? H2(g) ZnCl2(l)
• Practice problems pg 218 17

6
Double Displacement

• General Equation
• RU TS ? RS UT
• Reactants Two ionic compounds
• Probable Products Two new ionic compounds
• Example
• Na2CO3 CuSO4 ? Na2SO4 CuCO3
• Practice problems pg 220 18-19
