1. Other ways to Classify Reactions

2. Combustion Reactions
Chemical reactions that involve oxygen to produce energy (heat) so rapidly that a flame results.
*Special class of oxidation-reduction reactions
**Water and CO2 are products!!
C3H8(g) + 5O2(g) --- 3CO2(g) + 4H2O(g)
C(s) + O2(g) --- CO2(g)

3. Synthesis (Combination) Reactions
A chemical reaction in which a compound is formed from simpler materials
2H2(g) + O2(g) --- 2H2O(l)
2Na(s) + Cl2(g) --- 2NaCl(s)
Mg(s) + F2(g) --- MgF2(s)

4. Decomposition Reactions
A chemical reaction in which a compound is broken down into simpler compounds, or to the component elements.
2NaCl(l) --- 2Na(l) + Cl2(g)
2H2O(s) --- 2Hg(l) + O2(g)
