Reaction Types Combustion Reactions

Combustion Reactions “The Blow Up” – Matter reacts with O2 to produce a new product(s) and releases energy. Reactants = 2 (One MUST be O2) Products = This can vary

Combustion Reactions Fe(s) + O2 (g)

Combustion Reactions Special Case: Hydrocarbon + O2 A hydrocarbon is an compound that contains at least C and H Examples include: CH4 C2H5OH CH3COOH

Combustion Reactions When hydrocarbons are combusted, they always produce the same two products. CO2 carbon dioxide H2O water

Combustion Reactions Example: CH4 + O2 CO2 + H2O CH4 + 2O2 CO2 + 2H2O

Combustion Reactions Be careful when you are in the lab…… Heating = Burning Heating means: D Burning means: + O2 (g)

When writing net ionic equations Keep in mind that molecular compounds do not break into ions Molecular compounds are composed of all nonmetals H2O CO2 CH4 C3H7OH and many others.
