The clues that indicate a chemical change, such as color change, gas production, temperature change, and the formation of a precipitate, are generally reliable indicators. However, they are not infallible, as some physical changes can produce similar signs. Therefore, while these clues can strongly suggest a chemical change, confirming the change often requires further analysis or testing.

While clues like color change, gas production, and temperature change are common indicators of a chemical change, they are not always reliable on their own. It is important to consider these clues in the context of the specific reaction taking place and to look for multiple signs to confirm a chemical change has occurred. Testing with chemical indicators or analyzing the reaction using scientific techniques is often necessary for a more definitive answer.
