  1. Explanation:

    Yes, chemical reaction took place.

    Observation: The baloon gets inflated.

    But why?

    Vinegar is basically acetic acid.

    Baking soda is Sodium Bi-carbonate.

    Now, whenever baking soda is added to an aqueous solution of acetic acid (i.e. vinegar), the following reaction occurs:

    [tex]\rm NaHCO_{3}+CH_{3}COOH\rightarrow CH_{3}COO^{-}Na^{+} + CO_{2} + H_{2}O[/tex]

    Now, carbon dioxide gets released, which gets filled inside the balloon resulting in inflation of the balloon.
