1. Types of Reactions
Thursday, 4/17/14

2. Reaction Types There are four basic reaction formats Synthesis
Decomposition
Single-replacement (displacement)
Double-replacement (displacement)

3. Synthesis A + B → AB Example: Fe + O2 → FeO2
Two or more substances combine to form another substance
A + B → AB
Example: Fe + O2 → FeO2

4. Decomposition AB → A + B Example: CuCl2 → Cu + Cl2
One substance breaks down, or decomposes, into two or more simpler substances.
AB → A + B
Example: CuCl2 → Cu + Cl2

5. Single Displacement
One element replaces another in a different compound.
A + BC → AC + B
Example: Zn + H2S → H2 + ZnS

6. Double Displacement AB + CD → AC + BD AgNO3 + NaCl → AgCl + NaNO3
The positive ion of one compound swaps with another positive ion of a second compound.
AB + CD → AC + BD
AgNO3 + NaCl → AgCl + NaNO3
