Question
Which is not a clue that could indicate a chemical change? A Change in colorB Change in shape CChange in energy DChange in odor
Solution
The answer is B. A change in shape is not a clue that could indicate a chemical change. Chemical changes usually involve a change in the chemical properties of a substance, which often results in a new substance. This can be indicated by a change in color, energy (like heat or light being produced or absorbed), or odor. However, a change in shape usually indicates a physical change, not a chemical one. For example, if you mold a piece of clay into a new shape, you haven't changed its chemical composition, just its physical form.
