Some food packages are flushed with a relatively unreactive gas to reduce contact with more reactive air components. Which element is used for that atmosphere?

  1. Fluorine
  2. Oxygen
  3. NitrogenՃիշտ պատասխան
  4. Hydrogen

Բացատրություն

Nitrogen gas can provide a comparatively unreactive atmosphere inside suitable food packaging. It is not a sterilizing chemical that kills every microorganism, so the benefit should not be overstated as complete preservation.
