Question
Part A
Multiple Choice Question
While working on an activity to investigate physical and chemical reactions, a student mixes two clear liquids in a beaker. When the two clear liquids mix, the result is a mixture that contains a clear liquid and an orange solid precipitate.
Part A: The student concludes that a chemical reaction has occurred. Which piece of evidence best supports her claim?
A.
The resulting chemical turned a different color than the initial chemicals.
B.
The resulting chemical changed size.
C.
The resulting chemical has changed shapes.
D.
The resulting chemical changed temperature.
Part B
Multiple Choice Question
Part B: If the resulting mixture is filtered, separating the orange precipitate from the resulting liquid, what has occurred?
A.
The resulting mixture changed form.
B.
A chemical change occurred to the mixture.
C.
The resulting mixture experienced a physical change.
D.
A change of state has occurred to the mixture.

Part A: The best piece of evidence that supports the student's claim of a chemical reaction is:
**A. The resulting chemical turned a different color than the initial chemicals.**
This indicates that a new substance may have formed as a result of a chemical reaction.
Part B: If the resulting mixture is filtered, separating the orange precipitate from the resulting liquid, what has occurred is:
**C. The resulting mixture experienced a physical change.**
Filtering is a physical process that separates mixtures based on particle size, and it does not involve changing the chemical composition of the substances involved.
