    When vinegar and baking soda are mixed together, the gas that is formed is carbon dioxide (CO2). This is because baking soda (sodium bicarbonate, NaHCO3) is a base and vinegar (acetic acid, CH3COOH) is an acid. When these two are mixed, they undergo a chemical reaction called an acid-base reaction or neutralization reaction.

    The reaction can be represented by the following equation:

    NaHCO3 + CH3COOH → NaCH3COO + H2O + CO2

    In this reaction, the baking soda (base) reacts with the acetic acid (acid) to form sodium acetate, water, and carbon dioxide gas. The carbon dioxide gas is what causes the fizzing and bubbling when vinegar and baking soda are mixed together.

    So the correct answer to the question is option c) carbon dioxide.
