Methane Combustion

This reaction commonly occurs in gas stoves. It is very useful in

cooking since methane ignites easily and the gas is abundant. This gas can be found in almost every gas stove. It can also be used to power combustion engines.

Methane- Can be used as fuel and to power combustion engines

You can prove that combustion of methane has taking place when methane is ignited and CO and 2H O are the products of the reaction.

Combustion of Methane

CH + 2O

Methane was discovered by Alessandro Volta in November

1766. He heard about "flammable air" after reading Benjamin Franklin's newspaper and was inspired to search for the substance at Lake Maggiore. He captured the gas from the marshes and even isolated the gas by 1778. He also demonstrated to ignite the gas with an electric spark.

Methane is a hazardous compound because it can cause the following

  • Explosion- Igniting methane will cause a deadly explosion
  • Asphyxiation- Although methane is not toxic, it can displace oxygen causing victims to suffocate
  • Carbon Monoxide Poisoning- When natural gas, which is 97% methane, is burned, the combustion will release deadly carbon monoxide.

By Marshall Wong

Oxygen- Can be found in plants and algae through photosynthesis, the air, or the atmosphere

Safety Precautions

Carbon dioxide is an colorless gas and is non toxic. However, this gas can be deadly when it causes asphyxiation.

  • Make sure the area is ventilated when near carbon dioxide
  • Ensure there are no gas leaks
  • Have gas detection monitors/alarms
  • Ensure that containers are away from heat sources

Carbon dioxide can also be in the form of dry ice

  • Wear cryogenic gloves when carrying dry ice
  • Avoid carrying dry ice in a small area such as a in the trunk of a car or the passenger seat. If not able to, have ventilation systems or an open window to ventilate the gas
  • Store dry ice in ventilated areas and away from sources of heat
  • Do not store dry ice in any gas tight container
  • Use suitable containers to store dry ice
  • When opening lids containing dry ice, allow a few seconds for the gas to escape
  • DO NOT play games with dry ice
  • Keep the area ventilated to prevent asphyxiation
  • Wear safety goggles and a breathing mask to prevent methane gas from entering your body
  • When around methane, make sure there are no fire burning near methane to prevent explosions
  • When storing methane, keep the containers in well ventilated areas and away from heat sources such as sunlight
  • When carrying methane holders, wear heavy gloves to prevent frostbite from happening

The Law of Conservation of mass states that matter cannot created nor destroyed. This relates to the balanced chemical reaction because matter is not being created nor destroyed in this reaction. The reaction is taking the elements from the reactants and rearranging them to form new structures.

Carbon Dioxide- Can be used for beverage carbonation, greenhouse growing, reezing and chilling, respiratory stimulant, hydrauling fracturing, and welding processes

This is oxygen. It is a covalently bonded molecule. It contains 2 oxygen atoms.

This is a water molecule. It is a covalently bonded compound containing 2 hydrogen atoms and 1 oxygen atom.

This is carbon dioxide. It is a covalently bonded compound containing 1 carbon atom and 2 oxygen atoms.

This is methane. It is a covalently bonded compound containing 1 carbon atom and 4 hydrogen atoms.

Carbon Dioxide- Can mainly be found in the burning of fossil fuels, natural sources such as plants or volcanoes, plant and animal respiration, and volcanic eruptions.

You know that the combustion of methane has taken place when methane is ignited and an explosion or flame is created

Water- Water has been used for thermoelectric power, irrigation, domestic use, industrial use, aquaculture, and other public uses

Water- Sources of water include rain water, surface water (lakes, oceans, ect.) and underground water
