Their are 622.23 grams in 4 moles of Cu(NO2)2. Take the molar masses of all the elements and add them together. Then multiply by four because you have 4 moles not 1 mole.

Hope this helps you :)

151.55 x 4 you have to add the molar masses for each element together.

Write an equation that shows the formation of the chloride ion from a neutral chlorine atom

jeka57 [31]

The gaining of electron by an atom results in the formation of anion shown by the negative charge on the atom whereas lose of electron results in the formation of cation shown by positive charge on the atom. The atom lose or gain electron to complete their octet and get stable in nature.

The chlorine atom will gain an electron and form chloride anion with one negative charge on it. The chloride ion is more stable in nature compared to the chlorine atom due to complete octet of chloride ion by gaining of electron.

Electronic configuration of chlorine atom is:

$[Ne]3s^{2}3p^{5}$
