An indicator of a chemical change which is shown in the image (see attachment) is: A.) formation of a gas.
What is a chemical change?
A chemical change can be defined as a type of reaction that is typically characterized by a change in chemical composition and this leads to the formation of a new chemical substance.
This ultimately implies that, a chemical change would give rise to the chemical properties of matter by causing the transformation of one chemical substance into one or more different chemical substances.
In this context, we can infer and logically deduce that the formation of a gas is an indicator of a chemical change in the image (see attachment) shown below because the liquid turned to a gas when heat was applied.
