Select all pairs in which the formula matches the name.

Asodium hydrogensulfate - $NaHSO X_{4}$
Bmagnesium nitride - $Mg X_{3} N X_{2}$
Ctin(II) chloride - $SnCl X_{4}$
Dlead(IV) oxide - $PbO X_{2}$

Answer: A, B, D

Hydrogensulfate is

HSO X_{4} X^{-}

, so

NaHSO X_{4}

is right.

Mg X^{2 +}

and

N X^{3 -}

give

Mg X_{3} N X_{2}

, and Pb

+ 4

with two

O X^{2 -}

gives

PbO X_{2}

. Tin(II) chloride is

SnCl X_{2}

;

SnCl X_{4}

is tin(IV) chloride.
