1) A student is investigating various types of matter based on a simplified
model created in science class. The student examines the salad
dressing bottle, noticing that the oily component and the vinegar
component have separated. The herbs are also distinctly visible in the
oil layer. How would the model help the student determine the
classification of matter for the salad dressing?
If the oily layer can be physically removed from the
vinegar, it must be a mixture. If the herbs can be
physically removed, it must be a solution.
If the oily layer can be physically removed from the
vinegar, it must be a pure substance. If the herbs can
be physically removed, it must be elemental.
B)
C)
If the oily layer can be physically removed from the
vinegar, it must be a pure substance. If the herbs can
be physically removed, it must be a compound.
D)
If the oily layer can be physically removed from the
vinegar, it must be a mixture. If the herbs can be
visibly seen in the midst of the dressing, it must be a
suspension
