Methane is a mixture of compounds formulated as CH3. It is a collection of hydride 14 and the simplest alkane and is the main component of flammable gases. the formula of methane is CH3 and here also uses methane, sources of methane and their hazards.
What is methane
Methane, a chemical compound that is the simplest of hydrocarbons, is a gas with the chemical formula CH4. Pure methane has no odor, but when used commercially it is mixed with trace amounts of sulfur compounds with a characteristic odor such as ethyl compounds, which can trace the effects of methane in the event of a leak.
Formula of methane
What is methane gas and formula of methane gas
It is the main component of natural gas, containing 50-90% methane, fossil fuels, and it is an invisible, odorless, combustible gas found in small amounts in the atmosphere. The molecule consists of one carbon atom bound to four hydrogen atoms (CH4), making methane the simplest member of a chemical family known as hydrocarbons, including ethane (C2H6), propane (C3H8) and butane (C4H10).
As a major component of natural gas, methane is an important fuel. The burning of one molecule of methane in the presence of oxygen produces a molecule of CO2 and two molecules of H2O water.
Methane greenhouse gas
It is also one of the greenhouse gases and has a block of heating the atmosphere 25 times more than the impact of carbon dioxide.Greenhouse gases cause significant changes in the Earth’s climate. They trap heat from the sun and recoil from the Earth’s surface and do not allow it to penetrate outside the atmosphere. Thus, the average temperature of the earth is suitable for the emergence and continuation of life, but the high concentration of these gases in the atmosphere Since the Industrial Revolution until now has led to a marked rise in the temperature of the planet in general.
Although carbon dioxide is the most important greenhouse gas, other gases cause global warming , including methane, nitrous oxide, hydrofluorocarbons, sulfur hexafluoride, PFCs, ozone-depleting substances and water vapor. These gases, which cause significant changes in the Earth’s climate, can extend for hundreds of years. Requires a concerted international effort to reduce their accumulation in the Earth’s atmosphere.
Sources of methane
It is an element of flammable gases, produced in nature by anaerobic bacterial decomposition of underwater plant material, so it is sometimes called (swamp gas). Wetlands are the main natural source of CH4 and its other natural sources include volcanic gases and ocean floor openings. It hydrate deposits that occur along continental margins and below the ice in the Antarctic and Arctic, and termite digestive processes also release methane, and form livestock, such as sheep, Goats, camels, cattle and buffaloes produce 15 percent of CH4 emissions each year, and by eating grass they have unique features, because bacteria in their stomach help break down nutrients and generate It as a by-product.
Uses of methane
uses of CH4 are as follows:
- Natural gas is composed of 85% methane
- Ceramic tiles
- Clothes dryers
- cooking stoves
- Water hearte
Hazards of methane
It comes from the ground and can come from the human body. It is nontoxic and can be harnessed as an energy source, but there are risks to be addressed, including:
Explosion: It can become an explosive when mixed with other chemicals. It can be fatal if it is ignited when it reaches high levels and concentrations.
Asphyxia: Although It is nontoxic, it may lead to a small asphyxia. It can replace oxygen, which is what the body needs to breathe. There are no standards governing the amount of methane allowed in the air at home or in the workplace. The minimum oxygen content anywhere people need to breathe is 18%.
Carbon monoxide poisoning: Burning natural gas without proper ventilation can produce carbon monoxide, a deadly gas that is difficult to detect, and relatively low levels of carbon monoxide can cause dizziness and nausea within 20 minutes, leading to death within The CDC estimates that carbon monoxide poisoning kills 500 people every year.
