Answer:
E = 1.33 MeV = 2.13 x
J
v = wavelength = E / h = 2.13 x
/ 6.626 x
= 3.2 x
m
f = frequency = c / 3.2 x
m = 3 x
/ 3.2 x
= 9.375 x

<span>To convert between mass and number of moles, you can use the molar mass of the <span>substance.
Hope I helped : )

The change that exist in ionization energy that occurs between removing the first and second electrons from an atom is that the <span> ionization energy increases because the ratio of the protons to electrons increases. The answer is letter B.</span>
Answer:
trigonal planar
Explanation:
The molecule SO3 is of the type AX3. The molecule is symmetrical and non polar.
There are three regions of electron density in the molecule. This corresponds to a trigonal planar geometry. This means that the three oxygen atoms are arranged at the corners of a triangle. The bond angle is 120 degrees.
Answer:
Explained below.
Explanation:
A tennis player with two sneakers wouldn't bond to any other tennis player because he is already stable and complete with the 2 and doesn't need another players assistance to make him stand well.
However, helium atom with two electrons wouldn't bond to any other atoms because it is stable. This stability arises from the fact that it has two protons and 2 electrons, of which the 2 electrons completely fill its valence shell/outer most shell to make it neutral.
