identifying indicators of a reaction\nwhich indicator of a chemical reaction is shown in the picture?\n○ the formation of a gas\n○ the formation of a precipitate\n○ a change in energy

Answer

Brief Explanations:

The picture shows bubbles forming in a container, which is a sign of gas being produced during a chemical reaction. Formation of a precipitate would be a solid - like substance settling out of a solution, and a change in energy might be indicated by temperature changes or light emission. Here, the visible bubbles suggest gas formation.

Answer:

the formation of a gas
