2. Types of Chemical Reactions
Part Combustion Monday 11.3 Aqueous Net Ionic Reactions Tuesday

3. Combustion Reactions:
An exothermic reaction in which a substance combines with oxygen forming products in which all elements are combined with oxygen. (Burning) Energy is usually released in the form of heat and light.
General form for combustion of a hydrocarbon:
CxHy O2  CO H2O

4. Examples ____C3H8 + ____O2  ____C6H12O6 + ____O2  ____Mg + ____O2 5
