PLEASE HELP!!!
Which of the following properties cannot be
used to distinguish between FeS and a
mixture of iron and sulfur?
A) partial solubility in carbon disulfide
B) density
C) ability for the objects to be separated by
a magnet
D) appearance
E) mass
You can't really tell by their masses. It's very possible to amount them to the same mass because FeS is actually the same when you mix iron and sulfur, therefore producing the same mass.
