Which of the following is a compound? A) NE B) H2o C) iron fillings and sulfur mixed in a test tube d) Na?

I have never seen A) NE, I believe you mean Ne as in neon, which is not a compound it is only one molecule type. A compound is multiple molecules types mixed.


B) H2O is just one molecule because 2H is bonded to O


so it is a compound of two elements H and O


C) Fe and S is a mixture because the two elements do not react by themselves so there are two molecule types present.


d) Na is sodium which is an element, an element can NEVER be a compound.
