no
it is same as ammonium sulphate, (NH4)2SO4
Cobalt tetraoxosulphate (vi) ion
The formula for copper (II) tetraoxosulphate(IV) is CuSO4.
The chemical forrmula of potassium heptaoxodichromate(VI) is K2Cr2O7. The systematic IUPAC name is potassium dichromate (VI).
KUO4 is the chemical formula for potassium tetraoxodichromate(VI), a compound used in analytical chemistry and as an oxidizing agent.
The name of the ionic compound CoSO4 is cobalt(II) sulfate.
The name for K2Cr2O7 is potassium dichromate.
The chemical formula (not equation) of copper(II) sulfate is CuSO4.
Formula for potassium sulfide is K2S.
Cobalt tetraoxosulphate (vi) ion
The formula for potassium chlorate is KClO3.
This is an impossible reaction. However if you turn it around and do AgNO3 plus K2CrO4 then it is equal to Ag2CrO4 plus 2KNO3.
