Answer:
The right answer is "8.81 atm".
Explanation:
Given:
V = 5.00 L
Mass = 4900 g
MW = 32 g/mol
T = 350 K
Now,
Number of moles will be:



By using the ideal gas equation, we get
⇒ 
or,
⇒ 
By substituting the values, we get


Nitrogen dioxide is one of the primary components of air pollution. It is released by the combustion of nitrogen oxide.
<h3 /><h3>How do you calculate the percentage yield of nitrogen oxide?</h3>
Given:
- Mass of nitrogen oxide consumed = 1500 kg
- Mass of nitrogen oxide produced = 1500 kg
The given chemical equation of nitrogen oxide is:

Now, to calculate the percentage yield, the following conversion factor should be used:

Nitrogen dioxide = 2300 kg
The percentage yield will be:

Percentage yield = 65.2 %
Thus, the percentage yield of nitrogen dioxide is 65.2%.

Answer:
The answer is
D. Main sequence
Explanation:
Main sequence stars can be between one thousand times dimmer and one million times brighter than the Sun.
What is main sequence stars?
A main sequence star is any star that is fusing hydrogen in its core and has a stable balance of outward pressure from core nuclear fusion and gravitational forces pushing inward.
