I believe the answer is A
B cause it tells how it moves
The number of moles of NO₂ that would be produced from 3.9 mol of O₂ in the reaction is 5.13 moles NO2.
<h3>What is nitrogen?</h3>
Nitrogen is a monatomic gas. It is the most abundant gas present in the environment.
4.5 mol O2 x (2 mol NO2/ 1 mol O2) = 9 mol NO2
For 57% yield of the reaction
9 mol NO2 x 0.57 = 5.13 moles NO2.
Thus, the number of moles of NO₂ is 5.13 moles.

Answer:
0.4
The efficiency is defined as the work done divided by the heat provided at Th. ε = W/Qh = 400 J/1000 J = 0.4 The Carnot efficiency is given in terms of the high and low temperatures.
Hope this helps, please let me know if it is wrong.
λν=c f is solved for c, speed of light. v represents frequency and λ represents wavelength.
