Students are each given a 20-gram sample of an unknown solid compound in a clear plastic bag. They are instructed to break the m
aterial into smaller parts by gently hitting it with a hammer. Some of the parts break into large chunks and some look like a fine powder. Which statement correctly describes these broken pieces of the sample?
The fine powder pieces are individual atoms broken from the solid.
The larger pieces are still compounds and the smaller pieces are elements.
Each piece contains the same number of atoms.
Each piece contains the same proportion of different elements.
The larger pieces are still compounds and the smaller pieces are elements.
Explanation:
Compounds are a mixture of different elements. So, when we break in into smaller(fine powder) pieces we get the individual elements. While, the larger pieces are still compound (mixture of two or more elements).
