Wikipedia. License. Methane (US: , UK: ) is a chemical compound with the chemical formula CH4 (one atom of carbon and four atoms of hydrogen). It is a group-14 hydride and the simplest alkane and is the main constituent of natural gas.
What is L methane?
Methane is a colorless odorless gas. It is also known as marsh gas or methyl hydride. … Methane is a one-carbon compound in which the carbon is attached by single bonds to four hydrogen atoms. It is a colourless, odourless, non-toxic but flammable gas (b.p. -161℃).
What is the formula of methane and what are its properties?
Methane is a simplest of the saturated hydrocarbons with a chemical formula CH4. It consists of four hydrogen atoms and one carbon atom and is the simplest alkane. When natural methane reaches the surface of the atmosphere is called atmospheric methane and can be found under the seafloor as well as below the ground.
How much methane can kill you?
Asphyxiation becomes a risk when there are high concentrations of methane. This is because the methane displaces the oxygen. We need approximately 18% oxygen to breath, levels below 16% can be dangerous and levels below 10% can cause immediate loss of consciousness and inevitably death.
What is the Lewis structure of methane?
VSEPR calculation for methane, CH 4
|Valence electrons on central atom:||4|

What is number density formula?
Using the number density as a function of spatial coordinates, the total number of objects N in the entire volume V can be calculated as. where dV = dx dy dz is a volume element. If each object possesses the same mass m, the total mass m of all the objects in the volume V can be expressed as.
Is methane a base or acid?
Substances such as CH4 (methane) are not acidic as all four hydrogens are bound very tightly to the carbon and are not going anywhere. CH4 has a neutral pH, around 7.
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).
