5 True/False questions
element → substance in which the solute is dissolved or substance with the greater volume (amount)
chemical change → change of one substance to another that has different properties than the original substance
centrifuge → combination of two or more elements, compounds, or BOTH that can be separated by physical means that are NOT in a fixed proportion
weathering → device that spins liquids at high speeds to separate it into parts based on densities
electrolysis → mixture in which particles are larger than those in a solution but are NOT heavy enough to settle out. Which type of mixture has solute small enough, so it can't be filtered out?
