10. The three main states of matter are _______, _______, and _______.
D. solids, liquids, and gases
15. Which of the following terms represents a phase change from gas to liquid?
A. condensation
28. Which of the following is the formula used to calculate density?
A. mass/volume
3. The two main types of matter are __________ and __________.
D. pure substances; mixtures
6. In a mixture, a physical change does not change the identity of the contents and can be physically separated.
A. True
12. What is compressed gas?
C. Compressed gases are gases that are stored under pressure in cylinders. They can be very dangerous.
18. Each of the following are examples of a physical change except ________.
B. rusting metal or rotting fruit
29. The density triangle is a method used to calculate density, mass, or volume if one of the three quantities is known.
B. False
4. Each of the following are examples of pure substances except _______.
B. mixtures
8. Which of the following is an example of a homogeneous mixture?
B. air
13. All of the following are examples of compressed gas except ________.
B. pickle juice in a jar
19. Each of the following are examples of a chemical change except ________.
D. crushing, ripping, tearing, shredding, chopping, bending, or folding something
30. You have cube and the length of one side of the cube is 4 cm. The mass of the cube is 5.8 g. What is the density?
B 0.09 g/cm^3
1. What is the difference between a compound and a molecule?
B. All compounds are molecules, but not all molecules are compounds. Compounds are made up of different elements, and molecules can be made up of the same or different elements.
9. Which of the following is an example of a heterogeneous mixture?
A. Ryan's favorite food: salad
14. Which of the following terms represents a phase change from solid to gas?
B. sublimation
22. Each of the following are examples of physical properties except __________.
B. reactivity
31. The density of a horseshoe is 18.6 g/mL and the volume is 4.2 mL. What is the mass of the horseshoe?
C. 78 grams
27. Density is the amount of matter in a given volume. Which of the following is generally true about density of the 3 main states of matter?
A. Solids have high density, liquids have medium density, and gases have low density. Water does not follow this pattern because of the hydrogen bonds and shapes the molecules form in a given space.
7. In a mixture, a chemical change will change the properties of the contents because a new substance is formed. Chemical bonds of the reactants are broken, and new chemical bonds are formed in the products.
A. True
11. Which of the following is true about the particle movement for each state of matter?
B. Solid particles vibrate, liquid particles slide past one another, and gas particles move rapidly in any direction and bounce off one another.
23. Each of the following are examples of chemical properties except __________.
D. brittle
32. An object has a density of 4.49 g/mL. If the object has a mass of 16.7 g, what is the volume?
B. 3.72 mL
