Synthesis • Synthesis: to join together A + B AB Mg + O2 MgO H2 + O2 H2O
Decomposition • Decomposition: to break apart A B A + B KClO3 KCl + O2 H2O2 H2O + O2
Single Displacement • Single Displacement: when one element replaces one other element A + BC B + AC Mg + HCl H2 + MgCl2
Double Displacement • Double Displacement: when two elements switch places AB + CD CB + AD KI + CuNO3 CuI2 + KNO3
Combustion • Combustion: When a Carbon based compound (hydrocarbon) combines with Oxygen to make CO2 and H2O CH4 + O2 CO2 + H2O
