Every day, you breathe nitrogen and oxygen along with many other gases. Helium is inert and poses no threat at all except if you breathe only helium and you deprive yourself of oxygen. In theory, any gas can be breathed in small concentrations since the concentration is what determines hazardous effects. Even Oxygen can kill you if it is in too high of a concentration.
Oxygen is not hazardous to breathe in low concentrations. In fact, it is essential for sustaining human life. Oxygen concentrations up to 21% in the air are considered safe for breathing.
A gas with: low pressure, low concentration, low temperature.
No answer
Nitrogen is the most common - 78,o84 %; the lowest concentration is for ammonia - extremely low traces.
That's all down to the concentration. At low concentration, there's no effect at all. At a high concentration, a few minutes.
This is a gas having a high concentration.
A gas with: low pressure, low concentration, low temperature.
"Sweet gas" in petrochemistry is defined as a (natural) gas low in concentration of sulphur compounds (in particular H2S)
Low hazardous products are classified as Low danger.
No answer
The gas molecules move about randomly.
molecules moves through concentration gradient .and molecules move either in the form of ions or gas in the medium
An area of higher concentration to an area of lower concentration.
No. Mexican gas and diesel have a large concentration of sulfur.
by diffusion, from a low concentration to a high concentration of the molecule involved. so that the concentrations across the area are all equal, and an equilibrium is reached.

When the molecules of a gas spread throughout another medium, the process is called diffusion. The rate of diffusion can be influenced by temperature and pressure.
