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.

- く Complete the reaction in the drawing area below by adding the major products to the right-hand side. If there won't be any products, because nothing will happen under these reaction conditions, check the box under the drawing area instead. Note: if the products contain one or more pairs of enantiomers, don't worry about drawing each enantiomer with dash and wedge bonds. Just draw one molecule to represent each pair of enantiomers, using line bonds at the chiral center. More... No reaction. Explanation Check O + G 1.
