Name ___________________________________ Mixtures Practice A mixture (is, is not) a chemical combining of substances. In a compound the (atoms/molecules) are (chemically/physically) combined so that the elements that make up the compound (retain/lose) their identities and (do/do not) take on a new set of properties. The smallest identifiable unit of a compound is a(n) _________________________, which is made up of two or more _________________ which are chemically bonded. True or False: A mixture is always made up of a combination of elements. In a mixture, the substances (lose/retain) their identities. In a mixture the substances involved (can/cannot) be separated by a simple physical process. In a compound the elements involved (can/cannot) be separated by a simple physical process because the elements are (physically combined/ chemically bonded). True or False: An element can be broken down into a simpler substance The smallest identifiable unit of an element is a(n) _________________. From the following list of substances, circle the ones that are elements: Silver Gold Magnesium Sulfur Chromium Oxygen Wood Nitrogen Air Alcohol Salt Carbon dioxide Carbon Nickel Hydrogen Sugar Explain how to separate the sugar and water in a solution of sugar and water. How would you separate a mixture of alcohol and water? How would you separate sand and water? Classify the following as pure substances or as mixtures: Air Gasoline alcohol Water Sugar Gold Mercury Oxygen Salt water Classify the following as heterogeneous or as homogeneous: Sand & salt mixture Hydrogen Iron Salt Unfiltered air Iron with rust Pure water An apple Nitric acid Tossed salad Granite Wood Classify the following as an element, a compound, a solution, or a heterogeneous mixture: Aluminum Nitrogen Water & instant coffee Carbon dioxide Gasoline Carbon particles & Sugar and water Raisin bread sugar Sulfuric acid Water Air An orange Sulfur Grain alcohol A pencil Mercury
