How are the chemical properties of the gas different from the chemical properties of the baking soda and lemon juice

Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda, is a chemical compound with the formula NaHCO3. It is a salt composed of a sodium cation (Na+) and a bicarbonate anion (HCO3−). Sodium bicarbonate is a white solid that is crystalline, but often appears as a fine powder.

Explanation:

Approximately 5 percent of lemon juice is citric acid, which accounts for the sour taste of the lemon. When you mix an acid and a base, the result is a chemical reaction that creates a new product, with a neutral base. In the case of lemon juice and baking soda, the new product is carbon dioxide gas, water and salt.
