Types of Chemical Reactions Part 4 11.2 Combustion Monday 11.3 Aqueous Net Ionic Reactions Tuesday

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  CO2 + H2O

Examples ____C3H8 + ____O2  ____C6H12O6 + ____O2  ____Mg + ____O2  5 ____CO2 + ____H2O 3 4 6 ____CO2 + ____H2O 6 6 2 ____MgO 2

11.3 Net Ionic Equations Indicates only those particles that actually take part in the reaction.

1.Write a balanced chemical equation. AgNO3 (aq) + KCl (aq)  AgCl (s) + KNO3 (aq) 2. Write a complete ionic equation that shows dissolved ionic compounds as their free ions. Leave unchanged (s), (l), and (g). Ag+(aq) + NO3-(aq) + K+(aq) + Cl-(aq)  AgCl (s) + K+(aq) + NO3-(aq)

Ag+(aq) + NO3-(aq) + K+(aq) + Cl-(aq)  AgCl (s) + K+(aq) + NO3-(aq) 3. Cancel out any ions that appear unchanged on both sides. These are called “spectator ions” and are not involved in the reaction.

4. Write the net ionic equation with the remaining substances: Ag+(aq) + NO3-(aq) + K+(aq) + Cl-(aq)  AgCl (s) + K+(aq) + NO3-(aq) 4. Write the net ionic equation with the remaining substances: Ag+(aq) + Cl-(aq)  AgCl (s)

Examples: 2 __H2SO4 (aq) + __BaCl2 (aq)  __BaSO4 (s) + __HCl (aq) 2H+ (aq) + SO42- + Ba2+ (aq) + 2Cl- (aq)  BaSO4 (s) + 2H+ (aq) + 2Cl- (aq) Ba2+ (aq) + SO42- (aq)  BaSO4 (s)

__Fe (s) + __HCl (aq)  __FeCl2 (aq) + __H2 (g) 2H+ (aq) 2Cl- (aq)  H2 (g) Fe2+ (aq) + 2Cl- (aq) + Fe (s) H2 (g) Fe2+ (aq) + + 2H+ (aq) 

___Mg (s) + ___O2 (g)  ___MgO (s)
