The excited atom is positive when then neutral has no charge
Use your periodic table to get 1 mol. Look up the atomic masses. I'll round the numbers since every periodic table is different.
N = 14
O2 = 2 *16
Total = 30 grams / mol
Therefore 2 mols = twice as much = 60 grams.
If a substance causes another substance to be oxidized, that substance is an oxidizing agent. Likewise, the substance that is oxidized in an electrochemical reaction is always the reducing agent.
An Oxidizing agent is the one that gets reduced by accepting electrons. It causes oxidation because it makes the other substance lose electrons.
Oxidizing agents also transfer one electronegative atom like oxygen to the other chemical substance. Halogens are an example of oxidizing agents.
A reducing agent is the one that gets oxidized because it loses electrons in a redox reaction. It loses electrons and achieve a higher oxidation state. Lithium is an example of a reducing agent.

Answer:
a. n = 3
b. n = 4
Explanation:
n is just the number in front of the orbital, as n represents the energy level of the orbital.
The full moon shows all of one side of the moon in pictures it is all white. In a new moon you can't see the moon cuz it's all dark and in pictures it is all black. Thus becoming opposites of each other.
