Interpretation: Four possible clues should be listed that indicate a chemical change has taken place.
Concept Introduction: A property that is a characteristic of matter and is associated with a change in chemical composition is said to be chemical property.

Answer to Problem 33LC
Four possible clues that indicate a chemical change has taken place are:
- Formation of the precipitate.
- Transfer of energy.
- Production of gas.
- Change in color.
Explanation of Solution
A change that affects the chemical composition of a substance is said to be a chemical change. This change results in the formation of matter that possesses different composition than the original matter. In this change, the
- Formation of the precipitate.
- Transfer of energy.
- Production of gas.
- Change in color.
