<span>Higher energy = shorter wavelength
Frequency is one cycle over an amount of time (seconds)
So higher frequency = higher energy = shorter wavelength</span>
Pretty sure it’s C- hope this helps❤️
The equation for this reaction is
This means that for every mole of magnesium consumed, 1 mole of magnesium oxide is produced.
So, the answer is <u>0.094</u> moles.
Answer:
Option B. [Ar] 4s² 3d⁷
Explanation:
The condensed form of the electronic configuration of of cobalt, Co can be written by using the closest noble gas element before the cobalt element.
Cobalt has atomic number of 27. The noble gas element before cobalt is argon (Ar).
Thus, we can write the electronic configuration of cobalt, Co as follow
Co (27) => [Ar] 4s²3d⁷
