Question

I need help on my chemistry homework about binary compounds???
I need help matching these compounds. They can have the following names and the name can be used more than once!!

Here are the names you can use:
Binary Ionic
Binary Molecular
Ternary Ionic


Here are the compounds:
AlCl3
Ca(OH)2
KF
Pb(NO2)2
Ag2O
BaS
CO
CH4
(NH4)2S

Answer 1

OK, Binary Ionic has to have a metal and a non-metal, so AlCl3, KF, Ag2O, BaS

Binary Molecular has to have two non-metals, so CO and CH4

Ternary Ionic has to have metal/non-metal or ammonia/non-metal, so Ca(OH)2, Pb(NO2)2 and (NH4)2S
