Answer:
Evaporation is great for separating a mixture (solution) of a soluble solid and a solvent. The process involves heating the solution until the solvent evaporates (turns into gas) leaving behind the solid residue. ... This method is best for separating a liquid from a solution.
Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue ) the water passes through the filter paper (it becomes the filtrate )
Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. ... Due to the magnets, magnetic particles are being drifted by the movement of the drums. This can create a magnetic concentrate (e.g. an ore concentrate).
Explanation:
That's your answer.

There are two<span> types of </span>comet tails<span>: dust and gas ion. A dust </span>tail<span> contains small, solid particles that are about the same size found in cigarette smoke. This </span>tail<span> forms because sunlight pushes on these small particles, gently shoving them away from the </span>comet's<span> nucleus.</span>
The number of neutrons is determined from the difference of the atomic weight and atomic number. The atomic weight is 39 while the atomic number is 19. Thus, the number of neutrons is 20.
If two nonmetals with the same electronegativity bond, what type of bond will form then Non polar covalent bond (option D) will form.
