Types of Reactions Thursday, 4/17/14
Reaction Types There are four basic reaction formats Synthesis Decomposition Single-replacement (displacement) Double-replacement (displacement)
Synthesis A + B → AB Example: Fe + O2 → FeO2 Two or more substances combine to form another substance A + B → AB Example: Fe + O2 → FeO2
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
Single Displacement One element replaces another in a different compound. A + BC → AC + B Example: Zn + H2S → H2 + ZnS
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
