Here are the solutions to your questions: 43. Describe three ways mixtures can be separated. Give an example for each method. Filtration: This method separates an insoluble solid from a liquid using a filter medium that allows the liquid to pass through but retains the solid. Example: Separating sand from water*. Evaporation: This method separates a soluble solid from a liquid by heating the mixture, causing the liquid to turn into vapor and leave the solid behind. Example: Separating salt from water*. Decantation: This method separates an insoluble solid from a liquid, or two immiscible liquids, by carefully pouring off the top layer after the components have settled. Example: Separating oil from water or sand from water* (after sand has settled). 44. A cup contains sand, salt, and water. Explain step by step how you would separate all the components. Step 1: Dissolving and Decantation/Filtration (to remove sand) Add more water to the mixture in the cup and stir well. The salt will dissolve in the water, forming a salt solution, while the sand, being insoluble, will settle at the bottom. Carefully decant (pour off) the salt solution into another container, leaving the wet sand behind. Alternatively, pour the mixture through a filter paper in a funnel. The sand will be trapped on the filter paper, and the salt solution will pass through as the filtrate. Step 2: Evaporation (to separate salt from water) Heat the salt solution (the filtrate from Step 1) in an evaporating dish. The water will evaporate, turning into steam and leaving the solid salt crystals behind in the dish. Collect the steam by condensation if pure water is also desired (distillation), otherwise, the water is lost to the atmosphere. The separated components will be sand, salt, and water* (if condensed). 45. State the components of Integrated Science. The main components of Integrated Science typically include: Biology* Chemistry* Physics* Earth Science* (sometimes included)
