C?
Electrons are found orbiting around the nucleus of an atom in defined energy levels.
Answer:
1.5 atm is the pressure of dinitrogen tetroxide after equilibrium is reached the second time.
Explanation:
initially
4.9 atm 0
At equilbrium:
(4.9-2p) p
Pressure of nitrogen dioxide gas at equilibrium = 2.7 atm
So, (4.9-2p) = 2.7 atm
p = 1.1 atm
The value of equilibrium constant :
After addition of 1.2 atm of nitrogen dioxide gas more to the flask,will the reestablish an equilibrium in flask.
(2.7+1.2) atm 1.1 atm
At second equilibrium
(2.7+1.2-2x) atm (1.1+x) atm
The expression of :
Solving for x:
x = 0.3827 atm
The pressure of dinitrogen tetroxide after equilibrium is reached the second time:
(1.1+x) atm = (1.1+0.3827) atm =1.4827 atm ≈ 1.5 atm
1.5 atm is the pressure of dinitrogen tetroxide after equilibrium is reached the second time.
The correct answer is polarizing power increase.
The polarizing power of these ions grows as they move through a period because their charge increases and their size decreases. The size grows and the polarizing strength reduces as one descends a group. These two effects somewhat cancel each other out while travelling diagonally, preventing a noticeable change in attributes. As a result, the attributes of these diagonally oriented elements behave similarly.
What is polarizing power?
The capacity of a cation to distort an anion is known as its polarization power. The term "polarizability" refers to an anion's propensity to get polarized by a cation. The charge and radius of a cation affect its ability to polarize. The relationship between charge and radius and cation polarization power. Because they are directly proportional to one another, polarization power of the cation increases as cation charge increases.

This solution is "supersaturated".
A supersaturated solution is a solution that contains a higher than than the concentration of solute, slight unsettling influence or seeding causes crystallization of abundance solute.
Supersaturation is a condition of a solution that contains a greater amount of the dissolved material than could be dissolved by the solvent under ordinary conditions.
