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.

Calculate the frequency and wavelength for a photon of light with an energy of 3.2x10-19 J.
tamaranim1 [39]

Answer:

wavelength = 6×10⁻⁷m

f = 0.5 ×10¹⁵ Hz

Explanation:

Given data:

Energy of photon = 3.2×10⁻¹⁹ J

Wavelength of photon = ?

Frequency of photon = ?

Solution:

E = h.f

f = frequency

h = planck's constant

E = energy

f = E/h

f = 3.2×10⁻¹⁹ Kg.m².s⁻²/ 6.63×10⁻³⁴ m².Kg/s

f = 0.5 ×10¹⁵ s⁻¹

s⁻¹ = Hz

f = 0.5 ×10¹⁵ Hz

Wavelength:

speed of light = wavelength × frequency

wavelength = speed of light / frequency

wavelength =  3×10⁸ m.s⁻¹ /0.5 ×10¹⁵s⁻¹  

wavelength = 6×10⁻⁷m
