Centrifuges can work on mixtures that are
only. This kind of mixture can have properties that vary throughout a single sample. When a centrifuge spins, substances with
move toward the outside of the tube, and then the remaining liquid can be decanted.

If your mixture is
, you might be able to use evaporation or distillation.

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
