Chemistry Review - Student Sheet to Prepare for the Jeopardy Review Game
1. The name of the “universal solvent”. WATER
2. Orange juice with pulp is an example of this. HETEROGENEOUS MIXTURE
3. This subatomic particle is what helps scientists tell the difference between different
elements. PROTONS
4. This is the density for water, including units. 1 g/cm3
5. A scientist combines two liquids; a solid is formed and carbon dioxide gas is produced.
What are the products of this chemical reaction? A PRECIPITATE AND A GAS FORMED
6. The state of matter when the atoms/molecules are fixed in place and just wiggle. SOLID
7. This is the formula to find density. D = mass/volume
8. Determines the order of elements listed on the periodic table. ATOMIC NUMBER
9. An object has a volume of 4 mL and a mass of 2 g -this is what the object does in water. IT
FLOATS BECAUE THE DENSITY (O.5 g/cm3) IS LESS THAN WATER
10. Ripping paper, water freezing, and dissolving sugar in water are all examples of this type
of change. PHYSICAL CHANGE
11. In an exothermic reaction involving fire, this is evidence of an exothermic reaction. HEAT
IS GIVEN OFF/THE TEMPERATURE INCREASES
12. This is the density for an object has a mass of 14 g and a volume of 2 cm3 7 g/cm3
13. A solution is also known as this type of mixture. HOMOGENEOUS
14. Fe is an example of this basic building block of matter. ELEMENT
15. NaCl, otherwise known as table salt, is an example of this -when two elements bond
together. COMPOUND
16. This refers to the amount of material dissolved in a measure (volume) of liquid.
CONCENTRATION
17. This specific characteristic will cause matter to sink in water. DENSITY GREATER THAN
WATER (GREATER THAN 1 g/cm3)
18. This is the thing that gets dissolved. SOLUTE
19. Photosynthesis, milk rotting, and neutralization of vinegar and baking soda are examples
of this type of change. CHEMCIAL CHANGES – THE MATTER IS CHANGED
20. The state of matter of substance at room temperature if it has a melting point of 100F.
21. Acids have this pH range, relative to 7. pH 0 UP TO 7 ARE ACIDS
22. A change when the substances are not changed chemically. PHYSICAL CHANGE
23. When you put two or more materials together, but they don’t react. MIXTURE
24. When acids and bases react, this happens. NEUTRALIZE OR FORM WATER
25. The picture is an example of this.
MIXTURE, MORE THAN 1 SUBSTANCE
26. Steel is a metal that is made from iron and carbon. During the steel making process, iron and carbon are melted,
blended together, and then allowed to harden into a solid. The iron and carbon do not chemically react with each
other. After steel was made, 20 samples were taken from one piece and tested. Each sample contained 98% iron
and 2% carbon. Which of the following terms best describes steel?
A element
B compound
C homogeneous mixture
D heterogeneous mixture
27. Which is an example of a chemical reaction?
A nails rusting
B glass melting
C sugar dissolving
D alcohol vaporizing
28. Bromine (Br) is a liquid at room temperature. Oxygen (O) is a gas at room temperature (25° C).
Which of the following statements is true?
A The boiling point of oxygen is colder than room temperature.
B The boiling point of bromine is colder than room temperature.
C The melting point of oxygen is warmer than room temperature.
D The melting point of bromine is warmer than room temperature.
Mr. Jones set up a demonstration for his science class using two beakers. Each beaker contained 50 ml of a clear
liquid. The temperature of each liquid was 25° C. Mr. Jones placed a cube into each beaker at the same time. Each
cube measured 2 cm on all sides and had a mass of 5 grams. The results of the demonstration are shown in the
figures below.
Beaker 1
Beaker 2
29. What is the best question for students to investigate that would help explain the results of this demonstration?
A How long did it take for the cube in Beaker 2 to sink?
B Would a different sized beaker provide the same results?
C Will the cube in Beaker 1 sink if more liquid was added?
D What caused one cube to float and the other cube to sink?
30. Which of the following statements would best explain the results of this
demonstration?
A The cube in Beaker 1 has a lower density than the cube in Beaker 2.
B The liquid in Beaker 1 has a higher density than the liquid in Beaker 2.
C The cube in Beaker 1 is made from a different material than the cube in Beaker 2.
D The liquid in Beaker 1 has the same chemical composition as the liquid in Beaker 2.
