Substances and Mixtures
A. Matter: Substances and Mixtures
1. There are two main categories of matter: _______________________ and _________________________.
2. Matter that is always made up of the same combination of atoms is defined as a(n) ______________________.
a. The two kinds of substances are elements and
.
b. A substance that is made up of only one kind of atom, such as oxygen, is a(n) ______________________.
c. Atoms of two or more elements chemically bonded together, such as water, form (a)n ___________________.
3. Atoms of two or more substances that are physically blended but are not chemically
bonded together form a(n)
.
a. The relative amounts of the substances that form a(n)
can vary.
b.
is an example of a mixture that is a solid.
c.
is an example of a mixture of gases.
d. A mixture in which substances are not evenly mixed, such as granite, is called a(n) _______________ mixture.
e. A mixture in which two or more substances are evenly mixed on the atomic level
but not bonded together is called a(n)
mixture.
f. When you look at a _______________ mixture with or without a ______________, all the parts look the same.
g. A homogeneous mixture can also be called a(n) ______________________; these terms mean the same thing.
B. How do compounds and mixtures differ?
1. The formation of a(n) ___________________ occurs due to a chemical _____________________.
2. Mixing is a(n) __________________ change, so the substances that exist before mixing also exist in the mixture.
a. A(n)
has some of the same _____________________ properties as the substances that
make up the mixture.
b. A(n)
, in contrast, has physical properties different from the properties of the
substances that make up the compound.
3. The substances that form a(n) __________________ are not chemically ____________________ to one another.
a. The _____________________ that are combined in a mixture can be separated from one another using means.
b. In contrast, the substances that form a(n)
are bonded chemically, so the
only way to separate them is to break the chemical ___________________ —which is a(n)
__________________ change.

LESSON 1
Substances and Mixtures
Directions: Circle the term in parentheses that correctly completes each sentence.
1. Almost all matter can be classified into two major categories—substances and
(compounds, mixtures).
2. Matter that is made up of the same combination of atoms is called a (substance, mixture).
3. Substances that are physically blended but not chemically bonded together are called
(compounds, mixtures).
4. Mixtures have (exact, relative) amounts of the same substances.
5. Two types of mixtures are homogeneous and (solutions, heterogeneous).
6. Matter that is made up of chemically bonded atoms from two or more elements is
called a (compound, solution).
7. An example of a homogeneous solution is (granite, salt water).
8. Properties of a (compound, mixture) can be different from the properties of its elements.
9. The properties found in a (mixture, element) are the same before and after mixing has
taken place.
10. Physical methods can separate (mixtures, compounds).
11. A chemical change is needed to separate (compounds, solutions).
12. Some of the properties of the (substances, compounds) that make up a mixture can be
observed in the mixture.
13. Air is a (compound, mixture).
14. Water (H2O) is a (compound, solution).

LESSON 1
Substances and Mixtures
Directions: Use your textbook to answer each question.
1. Almost every type of matter is a substance or a mixture.
Classify elements and compounds as substances or mixtures. Explain your
classification.
2. Mixtures can be classified as heterogeneous or homogeneous.
Describe the characteristics of heterogeneous mixtures.
3. Homogenous mixtures are also known as solutions.
Describe the characteristics of homogeneous mixtures.
4. Although homogeneous mixtures and heterogeneous mixtures share some
characteristics, they are not the same.
Identify one way that heterogeneous mixtures and homogeneous mixtures are different.
5. Compounds and mixtures are similar in that both contain more than one
kind of matter.
Identify two ways that compounds and mixtures differ.

Key Concept In what three ways do compounds differ from mixtures?
Directions: On the line before each statement, write T if the statement is true or F if the statement is false. If the
statement is false, change the underlined word(s) to make it true. Write your changes on the lines provided.

2. Substances that existed before mixing still exist after substances are mixed.
3. Properties of substances are observed in a mixture.
