1) A compound 2) An element 3) A solution 4) A mixture
2. Which type of matter can be separated only by physical methods? 4) A compound
2) A pure substance 3) An element
1) A mixture
3. Which two types of matter are considered chemical pure substances?

change. Substance Y can be broken down by a chemical change. What can be concluded about
these substances?
1) X and Y are both elements 3) X is an element and Y is a compound

9. Which property correctly describes all compounds?
1) They are always homogenous 3) They can be physically separated
2) They are always heterogeneous 4) They cannot be decomposed
10. Which statement correctly describes a mixture?
1) A mixture can consist of a single element 3) A mixture can be separated by physical means
2) A mixture must have definite composition 4) A mixture must be homogeneous
11. One similarity between all mixtures and compounds is that both
1) Are heterogeneous 3) Combine in definite ratio
2) Are homogeneous 4) Consist of two or more substances
12. Bronze contains 90 to 95 percent copper and 5 to 10 percent tin. Because these percentages can
vary, bronze is classified as
1) A compound 3) A mixture
2) An element 4) A substance
13. When a teaspoon of sugar is added to water in a beaker, the sugar dissolves. The resulting mixture is
1) A compound 3) A heterogeneous solution
2) An element 4) A homogeneous solution
