Question
- When sample X is passed through a filter paper, a white residue, Y remains on the paper, and a clear liquid Z, passes through. When liquid Z is vaporized, another white residue remains. Sample X and Z are, respectively, best classified as:1 pointan element, a homogeneous mixturea homogeneous mixture, a heterogeneous mixturea heterogeneous mixture, a homogeneous mixturea compound, an elementNone of the above
Solution
The process described in the question is a filtration, which is a method used to separate solids from liquids in a heterogeneous mixture. Therefore, sample X is a heterogeneous mixture. The clear liquid Z that passes through is a single phase, so it is a homogeneous mixture. So, the correct answer is "a heterogeneous mixture, a homogeneous mixture".
