Six telltale signs that a chemical reaction has taken place are;
- a change in colour
- a change in temperature (substances grow hotter or colder)
- production of a solid (a precipitate)
- production of gas (shown by bubbling or fizzing)
- production of light or other energy forms (like sound)
- a smell is given off

∙ 12y agoActually, there are only five signs of a chemical change. These signs are: a production of gas, a change in temperature, a change in color, a formation of a precipitate, and a transfer of energy.

Do bubbles appear when a chemical change is happening?
Yes. They can. The clues of a chemical reaction are production of a gas, change in temperature, color change, production of a precipitate. If you take either baking soda or baking powder, and you add them to vinegar they both form bubbles in a chemical reaction.
