Combination and Decomposition Reactions
 Thermal decomposition of metal carbonates:
MCO3(s)  MO(s) + CO2(g)
 Combination of two elements to form a compound
Zn + S  ZnS
Organic Reactions
 Combustion Reactions
Reaction with oxygen gas to form CO2 and H2O.
C3H8(g) + 5 O2(g)  3 CO2(g) + 4 H2O(l)
 Substitution Reactions
Exchange of one atom or molecular fragment.
Organic Reactions
 Addition Reactions
Addition of two molecules together.
 Elimination Reactions
Ejection of a small molecule from a larger one.
Organic Reactions
 Isomerization (Rearrangement) Reactions
Change of shape of a molecule without gain or loss of any
atoms.
