Answer

Brief Explanations:

a. A chemical change occurred. Chemical changes result in the formation of new substances. In this case, gas bubbles were released, indicating the production of a new gas. Also, a temperature change (drop) is a sign of a chemical reaction. b. The release of gas bubbles shows that a new substance (the gas) was formed during the reaction between baking soda and vinegar. Temperature changes often accompany chemical reactions as energy is either absorbed or released. Since new substances were formed and there was a temperature - change, it was a chemical change.

Answer:

a. Chemical change b. Gas bubbles were released indicating new substance formation and there was a temperature change, which are signs of a chemical reaction.
