Orbital also called ''Electron cloud area"
Answer:
D
Explanation:
Because we have two reactants and product
<span>We can use the equation for the force of gravity to solve this question.
F = G M1 M2 / R^2
Let R be the radius of the planet.
f0 = G M1 M2 / (2R)^2
f0 = (1/4) x (G M1 M2 / R^2)
We can find an expression for f2.
f2 = G M1 M2 / (4R)^2
f2 = (1/16) x (G M1 M2 / R^2)
We can express f2 in terms of f0:
f2 = (4/16) x f0
f2 = 0.25 f0</span>
Answer:
(c) 6.91x10^14 Hz
Explanation:
Find the level energy of n=2 and n=5, using the formula:

where 


To jump from n=2 to n=5 the electron absorbs a photon with energy equal to
, using the next formula to find specific wavelength
to that energy

Where
is the speed of light (
) and
is Planck's constant (
). Solve for
:

The frequency of this wavelength is calculated with this formula:
