5.02 - Decomposition Reactions - 5:23



KEY CONCEPTS:

1 reactant --> 2 or more products

metal hydrogen carbonate --> metal carbonate + CO2 + H2O
(the metal can be any of the metals to the left of the aluminum ladder combined with a hydrogen carbonate. The end products are CO2 and H2O along with the metal bonded to the carbonate)

i.e: NaHSO4 --> Na2SO4 + CO2 + H2O

5.06 - Combustion Reactions - 8:15



KEY CONCEPTS:
-these reactions involve burning a hydrocarbon in the presence of oxygen. Hydrocarbons are compounds made by ONLY H and C atoms.

2 Types of Combustion Reactions:
i.) Complete Combustion (plenty of oxygen)
ii.) Incomplete Combustion (poor supply of oxygen)

Formulas for Combustion Reactions:

i.) Complete Combustion

C#H# + O2 --> CO2 + H2O

ii.) Incomplete Combustion Reactions:

C#H# + O2 --> CO2 + H2O + CO + C

**notice the difference in the Incomplete Combustion reactions
