Answer:
The only effect is that excess amount of energy absorbed by the electron will released to fall on lower energy state.
Explanation:
When transition occur from lower energy level to higher energy level require a gain of energy. Electron could not jump into higher energy level without gaining thew energy.
When electron jump into lower energy level from high energy level it loses the energy.
The process is called excitation and de-excitation.
Excitation:
When the energy is provided to the atom the electrons by absorbing the energy jump to the higher energy levels. This process is called excitation. The amount of energy absorbed by the electron is exactly equal to the energy difference of orbits.
De-excitation:
When the excited electron fall back to the lower energy levels the energy is released in the form of radiations. this energy is exactly equal to the energy difference between the orbits. The characteristics bright colors are due to the these emitted radiations. These emitted radiations can be seen if they are fall in the visible region of spectrum.

yes? Can I help you with a question? If so post it in the comments and ill help!
Explanation:
As an object begins to move faster, air resistance or drag increases. Drag means the amount of air resistance impacting an object when it is moving. ... When the air is denser, this slows down the movement of objects because the object has to shove aside heavier molecules

Answer:
The correct option is;
A) x = 2, y = 1
Explanation:
Here we have
....................(1)
....................(2)
..............(3)
From experiment (1), (2) it is observed that [A] is held constant and [B] is doubled of which the rate is also observed to be doubled, therefore, when you double a reactant which result in the rate being doubled, the order of the reaction with respect to the reactant is order 1, therefore, y = 1.
Similarly between reaction (2) and (3) when the concentration of the reactant B is doubled and A is held constant the rate of the reaction is multiplied by a factor of 4, therefore, the reaction with respect to that reactant is order 2, therefore, x = 2.
Therefore, the correct option is x = 2, y = 1.
Answer:
Average plate height: 67,4μm
Resolution: 3,10
Resolutin with increase N by a factor of 1,5: 3,80
Explanation:
Average plate height is the average between plate height of aspartame and caffeine.
Plate height is:
For aspartame:
H = 75,4 μm
For caffeine:
H = 59,33 μm
Average plate height is:
(59,3μm + 75.4μm)/2= <em>67,4μm</em>
The resolution formula is:
Replacing:
<em>R = 3,10</em>
<em></em>
As resolution is proportional to the square root of the number of theoretical plates, the increasing of 1,5 in the number of theoretical plates increases the resolution by a factor of √1,5 ≈ 1,22
That means resolution would be:
R 1,5N = 3,10×√1,5= <em>3,80</em>
