Separation by physical size is ______. Filtration Dela is helping his Aunt Starr on an archeological dig. His aunt gives him a bucket containing sand, rocks, and artifacts. What is the best way for Dela to separate the sand from the other materials? Use a screen to filter out the sand. Complete the sentence using one of the following words: filtration, distillation, or chromatography. Separation of two or more pure liquids by heating is distillation Complete the sentence using one of the following words: chromatography, distillation, or evaporation. Chromatography separates Complete the sentence using one of the following words: chromatography, distillation, or evaporation. In evaporation, solids can be What method would likely be used to separate a mixture of colored inks? chromatography If you want to separate different pigments extracted from leaves, which method of separation is most effective? chromatography This method describes separation by passing fluid through a selectively permeable layer. filtration This method describes separation based on differences in boiling points. distillation Which of the following processes is used to separate and collect alcohol from a mixture of alcohol and water? fractional distillation Which method of separation would be most effective to achieve the following diagram (A and B are two liquids with different boiling points). distillation In which of the following ways would one separate a miscible solution of benzene and chloroform? By distillation What separation technique involves passing a liquid through a material with small pores that allow some substances to pass through? filtration In a distillation process, which liquid component of the mixture passes through the condenser first? the one with the lower boiling point What separation technique separates liquids using differences in their boiling points? distillation Which method of separation would be most effective to achieve the following diagram? filtration What separation technique involves passing the mixture through a medium in which the components move at different rates? chromatography What method would likely be used to separate a mixture of colored inks? chromatography If you want to separate different pigments extracted from leaves, which method of separation is most effective? chromatography In which of the following ways would one separate a miscible solution of benzene and chloroform? By distillation What separation technique involves passing the mixture through a medium in which the components move at different rates? chromatography chromatography Which of the following is a viable method of separating gasoline from crude oil? distillation What separation technique is used to separate a dissolved solid from the liquid in which it is dissolved? evaporation
