Answer:
B. The time during which a collision between two molecules occurs is negligibly short compared to the time between collisions
Explanation:
Kinetic molecular theory postulates:-
- The gas is composed of small molecules are they are in continuous random motion and having elastic collisions with one another and also with the walls of the container.
- The molecules of the gas does not exert any kind of repulsive or attractive forces on each other and they their size is negligible as compared to the difference between them.
- Pressure exerted by the molecules of the gas results from the collisions which is happening between the molecules of the gas and the walls of the container.
- Average kinetic energy of molecules of the gas is directly proportional to absolute temperature.
Hence, The correct option is:- <u>B. The time during which a collision between two molecules occurs is negligibly short compared to the time between collisions. This is not an important postulate of the kinetic molecular theory.</u>
The answer would be decomposers
Answer:
<h2>252.9 kPa</h2>
Explanation:
The new pressure can be found by using the formula
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have
We have the final answer as
<h3>252.9 kPa</h3>
Hope this helps you
Answer:
nitrogen monoxide: NO
nitrogen dioxide: NO₂
Explanation:
Nitrogen monoxide is composed by 1 atom of O (prefix "mono-") and 1 atom of N. Nitrogen dioxide is composed by 2 atoms of O (prefix "di-") and 1 atom of N. As the oxigen atom in oxides has the valency -2 (it shares 2 electrons), the nitrogen has valency +2 in NO and +4 in NO₂.
