Question

What combination of name and formula is not correct?

a) Copper(II) oxide CuO
b) sodium nitride Na3N
c) silver chloride AgCl
d) zinc chloride ZnCl2
e) lead(II) oxide PbO2

I'm having trouble with naming compounds in general (ionic and covalent), any help will be greatly appreciated! Thank you!

Answer 1

2. Determine the name for TiCO3. (Remember that titanium forms several ions).

Answer 2

Lead(II) oxide --> PbO

since lead (II) => \(\large{Pb^{2+}}\)
oxygen => \(\large{O^{2-}}\)

hence we get lead(II) oxide ===> PbO

hence e) is not correct

Answer 3

TiCO3 is titanium (II) carbonate
