What is the formula for manganese II sulfide?

Answer 1

Copper sulphate ; CuSO4.5H2O (NB The 5H2O is the water of hydration held in the crystal ; like you hold a tennis ball in your hand).

Ammonium sulphide. ; (NH4)2S

Answer 2

Ammonium=NH4 Sulfide=S Sulfur has a -2 charge and ammonium has a =1 charge so in order to have a neutral compound there needs to be 2 ammonium compounds

------> (NH4)2S The numbers are subscripts

Answer 3

Ammonium: NH4+

Sulfate: SO42-

Ammonium sulfate: (NH4)2SO4

Answer 4

The formula for manganese II sulfide is MnS. In this compound, manganese has a +2 oxidation state and sulfur has a -2 oxidation state, so they combine in a 1:1 ratio to form the compound.

Answer 5

MnSO4 + (NH4)2S --> MnS + (NH4)2SO4

Answer 6

(NH4)2SO4

Answer 7

MnS

Answer 8

Mn2(SO4)2
