Answer 1

When lemon juice is added to baking soda ,they both react .Carbon diocide is formed in the reaction .The hissing sound is produced by the evolution of the gas.

Answer 2

Answer:

When baking soda (Sodium hydrogen carbonate) is mixed with lemon juice (citric acid), bubbles are formed. The bubbles are formed due to the evolution of carbon dioxide gas. This is a chemical change.

In this change, citric acid contained in lemon juice reacts with sodium hydrogen carbonate which results in the evolution of carbon dioxide gas.

Lemon juice + Baking soda → Carbon dioxide + Other substances

Citric acid Sodium

Hydrogen carbonate
