New Worksheet - Chemistry - Types of Reactions

There are five basic types of chemical reactions:
Decomposition reaction – a reaction that changes a compound into its constituent elements.
Formation reaction – a reaction that starts with two or more elements and produces one compound.
Combustion of a metal – the reaction of a metal with oxygen.
Complete combustion reaction – a reaction in which O2 is added to a compound containing carbon and hydrogen, producing CO2 and H2O.
Incomplete combustion reaction - when there is not enough oxygen available, a combustion reaction will only produce carbon monoxide or just carbon instead of carbon dioxide.
