FunFunFunNone Created by: lara hoganCreated on: 30-05-15 12:33 Defenition of an element A pure substance that is listed on the periodic table and only has one type of atom in it. 1 of 21 Difference between properties of metals and non metals metals are shiny, non-metals are dull, metals are good conducters of heat, non-metals are not, metals are malleable, non-metals are brittle 2 of 21 Defenition of a compound A pure substance made from more than one type of element chemically bonded together. 3 of 21 Defentition of a mixture An impure substance made from different elements or compounds. 4 of 21 Defenition of a molecule A cluster of atoms that are chemicaly bonded together 5 of 21 what is a solvent? the liquid in which a solute dissolves 6 of 21 what is a solute? the substance which dissolves into a liquid to form a solution 7 of 21 what is a solution? a mixture formed when a sloute has dissolved a solvent 8 of 21 what does soluble mean? describes a substance which dissolves 9 of 21 what does insoluble mean? discribes a substance which will not dissolve 10 of 21 What does saturated mean? containing the largest possible amount of a particular solute 11 of 21 what does unsaturatred mean? not containg the greatest possible amount of a particular solute 12 of 21 what is filtration? method for seperating an insoluble solid from a liquid 13 of 21 What is evaporation for? to seperate a soluble solid from a liquid 14 of 21 What is distilation? method to seperate a solvent from a solution 15 of 21 what is chromatography? seperationg dissolved substances from one another 16 of 21 what is magnetic attraction? the seperation of magnetic materials from non magnetic materials 17 of 21 what is decanting? a process of seperation allowing a mixture of solid and liqud to seperate by gravity 18 of 21 What is centrifuging? an apparatus which rotates at a high speed seperating substances of different densities 19 of 21 what does a seperating funnel do? it takes immiscible liquids and let one flow out so that they are seperated 20 of 21 what does immiscible mean? it means they do not dissolve in each other 21 of 21
