HEY everyone-I have attempted this nomenclature question, but I am completely unsure if I am doing it right or not...can u help??

Name the following substances:

a)   [Cu(Cl4)]2-      =>   tetrachlorocuprate(II)
b)   Ag(NH3)2+      =>   diamminesilver
c)   Cu(NH3)4SO4   =>   tetraammine cupricsulphate
d)   Al(H2O)6Cl3   =>   hexa-aquoaluminum chloride

[Kaleyrvt]

for b) the 2 is a subscript and the + is a superscript

looks right on to me.
