Answer: As a result, each excited electron in an atom emits a photon of a specific wavelength. To put it another way, each excited noble gas emits a distinct hue of light. This is a reddish-orange neon light.
696.32 mmHg is the final pressure of the gas.
<h3>What is an ideal gas equation?</h3>
The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.
Given data:
= 720 mmHg
= ?
= 2.5 mol
= 3.2 mol
= 34 L
= 45 L
Formula
Combined gas law

= 696.32 mmHg
Hence, 696.32 mmHg is the final pressure of the gas.

3NO₂ + H₂O→2HNO₃ + NO
n(NO)=n(NO₂)/3
n(NO)=0.83/3=0.277 mol
