Students in
a science class are working with various substances.
---Student 1 has a mixture.
---Student 2
has a compound.
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 release heat when the parts are
separated. | c. | Each part of the compound will gain mass during
separation. | d. | Only the mixture will go through a chemical
change. |

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 two substances chemically reacted with each
other. | b. | Because the parts could be
fairly easily separated. | c. | Because the two
substances were both solids | d. | Because the parts could not be easily
separated. |

One
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 the ingredients of these drinks are mixed, no chemical reaction
occurs. | c. | Each of these drinks are created by chemical
reactions. | d. | When these drinks are made, they foam, flash, fizzle, and give off

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 compound because there were two liquids combined
together. | 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 mixture
because no chemical reaction occurred. |

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 two
substances chemically reacted with each other. | c. | Because the parts of this combination could not be easily
separated. | d. | Because the ingredients, salt and water, were fairly easily
separated. |
