1. If you can easily see the different parts that make up a mixture, it is a -mixture. b. heterogencous c. solution d. need more information a. homogeneous 2. What do we call a substance that is the same throughout? b. mixture c. suspension d. need more information a. solution 3. Which of the following is a heterogeneous mixture? b. coffee c. salt water d. chicken soup a. Windex mixtures are mixed so that their properties are blended and every part of the 4. mixture is the same. a. homogeneous b. heterogeneous c. solution d. need more information 5. Is mass of sodium chloride an extensive property? b. no c. need more information a. yes 6. Which of the following is not an intensive property? a. color b. concentration c. density d. massExplanation / Answer
The answers are:
1) (b) heterogeneous
Because the mixture of different substances which are not combined chemically are called heterogeneous mixture and we can clearly see the different parts of the mixture.
2) (a) Solution
Because Solution is a homogeneous mixture that is composed of solvent and solute. The solute is dissolved in solvent and it is same throughout.
3) (d) Chicken soup
Chicken soup is heterogeneous mixture which is made of different substances which are not combined chemically whereas coffee, windex are homogeneous mixture and saltwater is a mixture.
4) (a) homogeneous
Because homogeneous mixture is the combination of substances which has the same proportions of its components throughout the given sample.
5) (a) yes
Because mass is an extensive property. An extensive property is a property which depends on amount of matter in a sample. Mass of sodium chloride is calculated using molar mass.
6) (d) mass
Mass is an extensive property not an intensive property. An intensive property does not depend on system size or amount of material in the system. And color, concentration and temperature are intensive properties.
