<h3>BALANCED EQUATION:-</h3>
Answer:
frequency = 2.07 x 10¹³ Hz
Explanation:
To find the frequency of the photon, you need to use the following equation:
E = hv
In this formula,
-----> E = energy (J)
-----> h = Planck's Constant (6.626 x 10⁻³⁴ J*s)
-----> v = frequency (Hz)
Since you have been given values for two of the variables (in the correct units), you can plug them into the equation and simplify to find the frequency.
E = hv <----- General Equation
E = (6.626 x 10⁻³⁴ J*s)v <---- Plug in Planck's Constant
1.37 x 10⁻²⁰ J = (6.626 x 10⁻³⁴ J*s)v <----- Plug in energy (given)
2.07 x 10¹³ = v <----- Divide both sides by 6.626 x 10⁻³⁴
Answer:
energy
Explanation:
The photon of light that is emitted as an electron drops back to its original orbit is energy and this energy is released during de-excitation process.
The electron is jumped into higher level and back into lower level by absorbing and releasing 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. For example if electron jumped from K to L it must absorbed the energy which is equal the energy difference of these two level. The excited electron thus move back to lower energy level which is K by releasing the energy because electron can not stay longer in higher energy level and comes to ground state.
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
Answer:
The entropy of the final solution decreases, as the reaction disorder is less.
Explanation:
The higher the temperature, the greater the heat of the reaction and the greater the disorder it has, so the entropy will increase ... But this is not the case, since the solution cools, decreasing the entropy proportionally.
Answer:
delta
Explanation:
A river delta is a landform where the mouth of a river flows into an ocean, sea, desert, estuary, lake or another river.
