SPI 0807.9.4 (Mixtures or Compounds)
A science student
examined a combination of two substances. Each substance consisted of small solid particles. They
were able to separate these two substances by using a magnet. By moving the magnet over this
combination, all iron particles were removed.
How can you know for certain that this was
mixture and not a compound?
a. | Because the parts could not
be easily separated. | b. | Because the two
substances chemically reacted with each other. | c. | Because the parts could be fairly easily
separated. | d. | Because the two
substances were both solids |

student claimed that soft drinks, tea, and Kool-aid drinks are mixtures. The teacher asked him to
provide some evidence to support his statement.
What is one fact that the student could share
to prove his claim?
a. | Water is the primary
ingredient for each of these drinks. | b. | When these drinks are made, they foam, flash, fizzle, and give off
heat. | c. | Each of these drinks are created by chemical

Compounds)
Jackson and
Tyrese worked together on an experiment in science class. The teacher gave them a beaker full of salt
water, and their mission was to separate the ingredients. They were able to separate the salt from
the H2O by boiling the water until all the liquid was
converted into steam.
How can you be sure that this
salt water was a mixture and not a compound?
a. | Because one ingredient was a liquid and the other
ingredient was a solid. | b. | Because the ingredients, salt and water, were fairly easily
separated. | c. | Because the parts of this combination could not be easily
separated. | d. | Because the two
substances chemically reacted with each other. |

Students in
a science class are working with various substances.
---Student 1 has a mixture.
---Student 2

Both students are attempting to separate the parts of their substances.
Which best
describes a result of the separation processes?
a. | Each part of the compound
will have different chemical properties. | b. | Only the mixture will go through a chemical
change. | c. | Each part of the compound will gain mass during
separation. | d. | Only the mixture will release heat when the parts are
separated. |

SPI 0807.9.4 (Mixtures or Compounds)
A scientist combined two liquids into a flask. The
temperature of the flask increased, the combination started bubbling, and a strong odor was given
off.
Was this an example of a mixture or a compound
and why?
a. | It is a mixture because no chemical reaction occurred. | b. | It is a mixture
because the temperature of the flask increased, and there was an odor. | c. | It is a compound
because a chemical reaction occurred. | d. | It is a compound because there were two liquids
combined together. |
