Answer 2

When baking soda (Sodium bicarbonate) is mixed with lemon juice(citric acid), bubbles are formed.

These bubbles are formed due to the evolution of carbon dioxide gas.

This is a chemical change.

In the change, the citric acid contained in lemon juice reacts with the baking soda or sodium bicarbonate) which results in the evolution of carbon dioxide gas.
