Which formula/name pair is incorrect? question 2 options: mn(no3)2 manganese(ii) nitrate mg(no3)2 magnesium nitrate mg3n2 magnesium nitrite mn(no2)2 manganese(ii) nitrite mg(mno4)2 magnesium permangana?

The name of a metal complex is written by writing the name of metal followed by its oxidation state and then the name of the anion bonded

a) Mn(NO₃)₂ : the metal is Manganese, the anion is nitrate and oxidation state of Mn is +2

so the correct name is Manganese(II) nitrate : correct option

b) Mg(NO₃)₂  : we can call it as Magnesium nitrate however it should be named as Magnesium(II) nitrate

c) Mg₃N₂ : the metal is Magnesium

However the anion is "nitride"

Hence the given name Magnesium nitrite is wrong

It should be : Magnesium (II) nitride

d) Mn(NO₂)₂ : The metal is Manganese , the oxidation state is two and the anion is Nitrite

Hence correct name is Manganese(II)nitrite

e) mg(mno4)2

The metal is Magnesium

the oxidation state is two

and thus name is

Magnesium permanganate

So completely wrong formula / name pair is Mg₃N₂:Magnesium nitrite

Answer- A-manganese(II) nitrate

Mn(NO3)2

manganese(II) nitrate

manganese(IV) nitrate

manganese nitride

Explanation:

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.

i think? ?
