Pure magnesium sulfide (MgS) is a white crystalline solid at room temperature.
Lime yellowish
It is a colourless solution.
The solution is colorless.

3Mg + 2Fe(NO3)3 ---> 2Fe + 3Mg(NO3)2
Mg(NO3)2 is called magnesium nitrate. You do not use the prefix di for the nitrate since this is an ionic compound, and it can only be (NO3)2 as nitrate has a -1 charge and Mg has a +2 charge.
as a displacement reaction has to occur when the metal is higher in the reactivity series thatn the metal in the salt. With your question this is not the case as sodium is higher than magnesium and so nothing will take effect.

Add something that magnesium will form an insoluble compound with. Sodium sulfate or potassium carbonate, maybe.
3Mg + 2Fe(NO3)3 ---> 2Fe + 3Mg(NO3)2
They could, since magnesium is more reactive than copper, and could displace it to form magnesium nitrate.

magnesium is more reactive than copper so,it displaces copper from its salt solution.

You don't: Magnesium nitrate is already neutral!
Will obtain magnisium nitrate{Mg(NO3)2} and H2 gas

There are 0.13 moles in 20 grams of magnesium nitrate.
