A teacher asks her students to classify the substances listed in the table shown as elements, compounds, or mixtures. A student claims that all of the substances are compounds. Which statement correctly describes the student’s claim?

• The student’s claim is correct because a substance that contains more than two of the same atom is a compound.

• The student’s claim is incorrect because a substance that contains more than one element is always a mixture.

• The student’s claim is incorrect because the atoms in the substances are physically combined to form a mixture.

• The student’s claim is correct because the atoms in the substances are chemically combined to form a compound.

The diagram shows the temperature variations in two regions (X and Y) as ocean depth increases. Which statement correctly describes the behavior of dissolved gases in each of the two regions?

• Region Y would contain more dissolved gases than region X as the water is deeper and colder.

• Region X would contain more dissolved gases than region Y as the water is deeper and colder.

• Region Y would contain more dissolved gases than region X as the water is shallower and warmer.

• Region X would contain more dissolved gases than region Y as the water is shallower and warmer.
