Methane is a chemical compound with the molecular formula CH4. It is the main component in natural gas. Methane is considered the simplest of alkanes, compounds that consist only of hydrogen (H) and carbon (C) elements. Methane is an odorless, colorless, tasteless gas that is lighter than air.
What is the main producer of methane?
The largest source of anthropogenic methane emissions is agriculture, responsible for around a quarter of the total, closely followed by the energy sector, which includes emissions from coal, oil, natural gas and biofuels.
What is the most important source of methane?
The largest sources of methane emissions from human activities in the United States are oil and gas systems, livestock enteric fermentation, and landfills.
What is the smell of methane?
In fact, methane by itself is odorless. If you are using methane in the form of natural gas, however, it will have a scent. This is the typical “gas” odor that most of us will recognize from when we turn on a cast stove at home before we light the burner.
What is the Lewis structure of methane?
VSEPR calculation for methane, CH 4
|Valence electrons on central atom:||4|
|4 H each contribute 1 electron:||4|
Is methane a poisonous gas?
Methane gas is relatively non-toxic; it does not have an OSHA PEL Standard. Its health affects are associated with being a simple asphyxiant displacing oxygen in the lungs. … Methane is extremely flammable and can explode at concentrations between 5% (lower explosive limit) and 15% (upper explosive limit).
What does methane look like?
Methane (CH4) is a colorless, odorless, and highly flammable gas composed of one carbon atom and four hydrogen atoms. It can be produced naturally and synthetically, and when burned in the presence of oxygen, it produces carbon dioxide and water vapor.
