Answer: In creating a covalent bond, it would be best to bind oxygen to carbon (C ).
Covalent bonds result from electron-sharing between two atoms. One carbon atom combines with two oxygen atoms. Thus, the carbon dioxide molecule has two C=O bonds. Carbon dioxide is a very common covalent bond.
12 moles are needed because stoichiometry is 1:2

The total pressure 1566 mm Hg.
Pressure is the force applied perpendicular to the floor of an object per unit location over which that pressure is shipped. Gauge strain additionally spelled gage pressure is the pressure relative to the ambient stress. pressure.
The SI unit of stress is pascal which is identical to one newton in keeping with rectangular meter. apparently, this name was given in 1971. earlier than that pressure in SI became measured in newtons in line with square meter.
Partial pressure of Argon = 429 mm Hg
Partial pressure of Neon = 1.2 atm
∵ 1 atm = 760 mm Hg
=> 1.2 atm = 1.2 * 760 mm Hg
= 912 mm Hg
Partial presser of He = 225 mm Hg
S0, Total pressure = Par + P ne + P he
= ( 429 + 912 + 225 ) mm Hg
= 1566 mm Hg

a) figure describe ionization energy , electron affinity & electron negativity
b) figure describe Atomic Radius
c) does represent anything
Electronegativity : An atom attracted the bond pair of electrons in a covalent bond is called electronegativity of an element. H-->Cl
Ionization energy : The amount of energy is required to remove of an electron from an isolated gas atom is called Ionization energy. M + IP-----> M+ + e-
Electron affinity: The amount of enery is released when an electron added to an isolated atom is called electron affinity.
X + e- ------> X- =- EA
Atomic radius ; The distance between the center of neuclies and outer most shell is called atomic radius.
The coins in 1991 had more copper in them compared to the coins today. So, that is why it worth 3.3p.
