Other ways to Classify Reactions

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)

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)

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)
