What Is Chemistry?
True/False
1. Chemistry is the study of the interactions of matter with other matter and with energy.
True; Easy
2. Matter is anything that has a mass and takes up space.
True; Easy
3. Air found inside an empty chamber cannot be classified as matter.
False; Easy
4. Physical properties are characteristics of matter that describe how matter changes form in
the presence of other matter.
False; Easy
5. Chemical properties are characteristics that describe matter as it exists.
False; Easy
6. A physical change occurs when a sample of matter changes one or more of its physical
properties.
True; Easy
7. A burning sparkler is an example of chemical change.
True; Easy
8. Ice melting is an example of a chemical change.
False; Easy
9. A sample of matter that has the different physical and chemical properties throughout is
called a substance.
False, Easy
10. An element can be broken down into simpler chemical substances by chemical reactions.
False; Easy
11. A compound is a combination of more than one element.
True; Easy
12. A compound‘s physical and chemical properties are different than the physical and
chemical properties of its constituent elements.
True: Easy
13. Table salt has the same physical properties as its constituent elements, sodium and
chlorine gas.
False; Medium
,14. Carbonated water, before it is opened, is an example of heterogeneous mixtures.
False; Easy (the CO2 dissolved in the water makes it homogeneous. However,
students will think of the water after it is opened, the CO2 bubbles are present
making it look like it is heterogeneous.
15. Solution is another word used to describe homogenous mixtures.
True; Easy
16. A metal is an element that is brittle at room temperature.
False; Easy
17. Elements that have properties of both metals and nonmetals and are called antimetals.
False; Easy
18. Nonmetals do not conduct electricity or heat very well.
True; Easy
19. Science is the process of knowing about the natural universe through observation and
experiment.
True; Easy
20. A hypothesis is a general statement that explains a large number of observations.
False; Easy
21. Experiments are not performed if a hypothesis exists on the issue to be tested.
False; Easy
22. A law is a specific statement that is thought to be never violated by the entire natural
universe.
True; Easy
23. Science is concerned only with the natural universe.
True; Easy
24. Physics and astronomy are scientific fields concerned with the fundamental interactions
between matter and energy.
True; Easy
25. Chemistry is widely regarded as the language of science.
False; Easy
26. A qualitative description implies a description of the extent to which a compound is used
in a reaction.
False; Easy
27. The temperature outside is 95 degrees Fahrenheit; this is an example of a quantitative
description.
True; Easy (students might not know the color of rhodochrosite unless they look it
up)
, 28. A qualitative description means knowing how much of something is present.
False; Easy
