Anyone please help! :(

jfraser · Answer

SrBr2 is metal-nonmetal.

anonymous · Answer

Then it is also a molecular compound, right? @JFraser

thomaster · Answer

there are metals, molecular compounds and ionic compounds

thomaster · Answer

so SrBr2 is not a molecular compound
it's ionic because it's composed of metal/non-metal

Molecular compounds are composed of non-metal/non-metal combinations that will not separate in solution and provide ions

anonymous · Answer

@thomaster so C would be the correct answer?

thomaster · Answer

PbO (lead oxide) is made of lead and oxigen, lead is metal and oxigen is a non-metal
SO3 (sulfur trioxide) is made of sulfur and oxigen which are both non metals 
P3As (phosphorus arsenic) phosphorus is a non-metal and arsenic is a metaloïde
LiI (lithium iodide) is made of lithium and iodine which are alkalimetal and halogen

So yes sulfur trioxide is a molecular compound
