Ni+2 SO4-2 <--- These are the ions and their charges. The charges have to have a net charge of zero, so one +2 nickel ion cancels out one -2 sulfate ion.
The final formula would then be NiSO4
The chemical equation for when nickel is placed in sulfuric acid is as follows: Ni(s) + H2SO4(aq) → Ni2+(aq) + SO42-(aq) + H2(g).
The chemical reaction is:
Mg + NiSO4 = MgSO4 + Ni
NiSO4 is the formula for nickel sulfate.
The formula is NiSO4.
Ni(OH)2 + H2SO4 = NiSO4 + 2H2O
Ni2S3
NiS
Ni2(SO4)3
Ni2(SO4)3
There are two kinds of iron sulfate: iron (II) sulfate has the formula FeSO4 and iron (III) sulfate has the formula Fe2(SO4)3.
Ru2(SO4)3.
There is 1.42 x 10^-2 moles of formula units that are in 5.67 g of iron III sulfate.
That would be chromium(II) sulfate, but really, chromium mostly exists as Cr(III) or Cr(VI), which would change the formula.
The chemical formula for chromium (III) sulfate is Cr2(SO4)3.
Ni2(SO4)3
== Since Nickel(III) has a +3 charge and Nitrate (NO3) has a -1 charge, the chemical formula for nickel(III) nitrate would therefore be Ni(NO3)3
Gallium (III) sulfate, otherwise known as octadecahydrate, has a chemical formula of Ga2(SO4)3·18H2O.
This chemical formula is Nb2(SO4)3.
The chemical formula of nickel silicate is NiSiO3.
Ni2S3
Y2 (so4)3
There are two kinds of iron sulfate: iron (II) sulfate has the formula FeSO4 and iron (III) sulfate has the formula Fe2(SO4)3.
The chemical formula is Fe2(SO4)3 (anhydrous).
Nickel oxide is Ni(III)2O3, which does balance.
the formula is Ni3(PO4)2 :) The correct answer is Ni PO4, the answer shown is for Nickel II phosphate.
