Students are each given a 20 gram sample of an unknown solid compound in a clear plastic bag. they are instructed to break the material 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 pieces of fine powder are individual atoms.
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.

Someone offer some answers to this, i will give 98 coins and mark as brainliest! i will put the rest of the lab down in the comments,solutions pre-lab questions: in this lab, you will make fruit drinks with powdered drink mix. complete the pre-lab questions to get the values you need for your drink solutions. calculate the molar mass of powered fruit drink mix, made from sucrose (c12h22o11).using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 m solution of 100 ml. (hint: use molarity = to find the moles of drink mix, then convert moles to grams using a mole conversion.)what mass of powdered drink mix is needed to make a 0.5 m solution of 100 ml?
