Answer 1

The correct option is B

It is a chemical change

Formation of bubbles after adding lemon to baking soda (Sodium bicarbonate) is a chemical change because new product is formed in this. When baking soda is mixed with lemon juice a chemical change occurs in which a new substance carbon dioxide and heat is produced. In the reaction we can see the formation of new substance which is the property of a chemical change.
