A student has a sample of a solid dissolved in a liquid. The task is to separate the mixture into its pure components. What question is best asked in the design of the experiment to determine how to separate the components?

A) Can the solution be filtered using filter paper and a funnel?
B) Can the solid be physically removed with forceps or a small manipulative?
Eliminate
C) Will the solvent evaporate at a different temperature than the solute in a distillation procedure?
D) Will the solid form a distinct layer on the bottom of the mixture when the mixture is not in motion?

Identify the amplitude on the diagram and give the correct description. question 3 options: a because amplitude is the distance from wave crest to wave crest. b because the wavelength shows amplitude. c because amplitude is the distance between a crest (or trough) and rest. d because wavelength show amplitude.
