Chemistry help!!! Transition metal cations?

Question

What are the charge on the transition metal cation in each of these, also what are the compund names?
HgS
CuCO3
NiCl2
Co(NO3)3
Cu(OH)2
FeSO4
THANKS :)

Answer 1

HgS --- hydrargyrum iodide or Mercury iodide

Charge for S is -2 so obviouslyy Hg would have +2 to form as a compound!!!



CuCO3 --- copper carbonate

Charge of CO3 is -2 , and so Cu will have +2 charge



NiCl2 ----- Nickel chloride

Cl has -1 charge and Ni, it has +2 forming NiCl2

[Note: The 2 beside Cl represents the charge of the Nickel. This charge may vary from compound to compound based on the element which it bonds]



Co(NO3)3 --- Cobalt Nitrate

Charge of NO3 is -1 , Co would have +3 [Because of the 3 beside NO3]



Cu(OH)2 ---- Copper hydroxide

OH has -1 and Copper has +2



FeSO4 ----- Iron Sulfate

SO4 has -2 and Fe has +2
