Combustion

Combustion reactions occur when a compound or element react with oxygen to release energy and produce an oxide.

Also sometimes referred to as hydrocarbon combustion
Definition: A combustion reaction is when a hydrocarbon reacts with Oxygen to produce Water and Carbon Dioxide
  • CXHY + O2 >--> CO2 + H2O where X and Y represent integers
  • Natural gas (methane) is burned in furnaces to heat homes.
wCH4 + 2 O2 --> CO2 + 2H2O
  • An acetylene torch is used to weld metals together
2C2H2 + 5O2 >--> 4CO2 + 2H2O
  • Carbohydrates like glucose combine with oxygen in our body to release energy.
C6H12O6 + 6O2 >--> 6CO2 + 6H2O
