<u>Answer:</u> The number of dozen of eggs are 12
<u>Explanation:</u>
We are given:
Total number of item = 144
This is equal to 1 gross of iems
Converting the given items into dozens, we use the conversion factor:
1 dozen = 12 items
Converting the items, we get:
Hence, the number of dozen of eggs are 12
Answer:
The answer to your question is:
Explanation:
1) Increasing atomic radius:
Oxygen 74
Aluminum 143
Potasium 227
2) Increasing electronegativity
Neon -
Aluminum 1.61
Sulfur 2.58
Oxygen 3.44
3.-
Electronegativity: is the measure of the tendency of an atom to attract a pair of electrons.
Ionization energy: is the quantity of energy that an isolated, gaseous atom must absorb to discharged an electron, resulting in a cation.
4.-
Atomic radius increases as we move down on the periodic table.
Atomic radius is the distance from the center of a nucleus to the outer most shell containing electrons.
5.-
Sulfur = 1s² 2s² 2p⁶ 3s² 3p⁴
Neon = 1s² 2s² 2p⁶
<em>Answer:</em>
There are two major resonance contributors for the en-amine. One contributor have no formal charges, only have one lone pair at N while the other one has positive and negative formal charges.
<em>Explanation:</em>
An en-amine is formed by the condensation reactions of aldehydes or ketone with secondary amine.
The contributor<em> </em>I have no formal charges. It has only one lone pair at Nitrogen atom.
The contributor II has +1 formal charges at N, and -1 formal charges at α Carbon.
Please see attachment. The resonance contributor are given.
