<span>Generally, a hydrogen bond can be characterized as a proton shared by two lone electron pairs. It occurs when a hydrogen (H) atom, covalently bound to a highly electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F), experiences the electrostatic field of another highly electronegative atom nearby.
Among the choices in the bond (-N...H-O) one side of the Hydrogen is bonded to a highly electronegative atom with a lone pair (-N) and the other side is directly bonded with a highly electronegative atom (O-).
So -N...H-O- shows a hydrogen bond.</span>

Answer:
1.82x10⁻¹⁹Joules is the energy of the photon that is absorbed by the electron.
Explanation:
The energy of a photon is given by the equation:
E = h×ν
<em>Where E is energy of the photon in Joules.</em>
<em>h is Planck's constant (6.6262x10⁻³⁴Js)</em>
<em>And ν is frequency of the photon (In Hz = s⁻¹)</em>
<em />
The frequency of the photon is 2.74x10¹⁴Hz. That means its energy is:
E = 6.6262x10⁻³⁴Js × 2.74x10¹⁴s⁻¹
E =
<h3>1.82x10⁻¹⁹Joules is the energy of the photon that is absorbed by the electron</h3>

"The inert gases are obtained by fractional distillation of air, with the exception of helium which is separated from a few natural gas sources rich in this element, through cryogenic distillation or membrane separation. For specialized applications, purified inert gas shall be produced by specialized generators on-site. They are often used by chemical tankers and product carriers (smaller not a big as well as the tendency of inert gases vesselshtop specialized generators are also available for laboratories."
