What is methane?
Few people know what methane is and whythis chemical element is needed. Methane is the simplest hydrocarbon, which is a gas that does not have color and odor. Its chemical formula is CH4. Methane is lighter than air and is slightly soluble in water.
So that a person can feel methane, odorants are specially added to it (these are substances that actually have an unpleasant smell of gas).
Chemical properties of methane
- When burning in air, it forms a blue flame and generates an energy equal to 39 MJ per 1 cubic meter.
- It freezes at a temperature of 184 degrees (at normal pressure).
- Reacts with substitution reactions with halogens.
- It decomposes at temperatures above 1400 degrees.
- Under certain conditions, it is oxidized to formic acid. This requires a temperature of 150 - 200 degrees and a pressure of 30 to 90 atmospheres.
Get this gas can be in the laboratory and at home. How to do it, read in the article How to get methane.
Danger to humans
- At a very high concentration of methane in the air, poisoning can occur, the symptoms of which are increased heart rate, impaired coordination of movements and an increase in the volume of breathing.
- Also methane is dangerous asphyxiation and oxygen starvation, as it displaces oxygen from the air.
- With constant contact with methane in largethere may be a violation of central and autonomic nervous systems (increased excitability and blood pressure, convulsive twitching of the eyeball).
It is interesting to know that Methane is also called the simplest oral steroid. About him you can find out here: How to take methane.
