Does xenon react with nitrogen and explain why
KiRa [710]
No, xenon will not react on Nitrogen because xenon only reacts with oxygen and fluorine. Xenon only reacts with the 2 elements because these 2 elements contain a strong electronegative element which is high in energy barrier that can move the electrons inside xenon elements.  Xenon is an element with a symbol of Xe, it is odorless and colorless gas. Common uses of xenon are flash lamps and arc lamps. Xenon is a luminous element, it glows when placed near to high voltage electric field.

What is the molarity if a solution that contains 289 grams of sugar in a 2 liter solution?? Molar mass of source is 342.2965g/mo
Olegator [25]

<u>Answer;</u>

= 0.422 M

<h3><u>Explanation;</u></h3>

Molarity or concentration is the number of moles of a solute in 1 liter of a solution.

Therefore; Molarity = n/V ; where n is the number of moles and V is the volume of the solution in L.

Number of moles = Mass/molar mass

                             = 289 g/342.2965g/mol

                             = 0.844 Moles

Therefore;

Molarity = 0.844 moles/ 2L

              = 0.422 M

The process where bacteria takes nitrogen out of the air and makes it usable for other organisms is called
Likurg_2 [28]

Answer:

The process is called Nitrogen fixation

Explanation:

The nitrogen fixation is a process carried out by some prokaryotic microorganisms (bacteria), specifically those have the presence of the nitrogenase enzyme. The bacteria absorb the atmospheric nitrogen (N2) from the roots of plants, and the nitrogenase enzyme, with the help of two proteins that act as electron donors and acceptors (nitrogenase complex) reduce the nitrogen to ammonia (NH3), then the ammonia is ionized to NH4+ (ammonium). Followed by that, the ammonia is oxidated to nitrates and nitrites, which are finally absorbed again by plants.
