Question

Quizplus · Accepted Answer

A combination of sugar and iron filings is a physical combination of two substances. Each substance retains its own properties and can be separated by physical means. Therefore, it is best described as a mixture. A colloidal suspension involves particles that are larger than those in a solution but smaller than those in a suspension. A tincture involves dissolving a substance in alcohol. An isotope refers to variations in the number of neutrons within the atoms of a particular element.
