Want this question answered?
P:co2+h2o= oxygen AR: oxygen to make co2+ h2o
Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
Co2+ has 25 electrons with the configuration: [Ar] 4s2 3d5 no its [Ar]3d^7
I am assuming that the question is for Co2+ ion. and the answer is [Ar] 3d5 4s2
The main molecules that make up air are nitrogen (N2), oxygen (O2), and small amounts of other gases such as carbon dioxide (CO2), argon (Ar), and trace amounts of water vapor (H2O).

Argon (Ar) is an atom not a molecule. An atom is singular whereas a molecule is a group of two or more atoms.
Its composition is nearly all CO2: but it also containsCO2: 96.5%N2: 3.5%SO2: 0.015%Ar: 0.007%H2O: 0.002%CO: 0.0017%He: 0.0012%Ne: 0.0007%

[Ar] 3s1
[Ar] 4s2 3d7
Nitrogen (N2) ~78% Oxygen (O2) ~ 21% Argon (Ar) ~0.9% Carbon Dioxide (CO2) ~ 0.04% Neon (Ne) ~ 0.02% Remainder < 0.001% Oh, don't forget: Water (H2O) highly variable! Maximum is ~2% at 25C

Cobalt electron configuration is [Ar]3d7.4s2.Cobalt(2+) electron configuration is [Ar]3d7.
