Answer 1

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:

$\rm NaHCO_{3}+CH_{3}COOH\rightarrow CH_{3}COO^{-}Na^{+} + CO_{2} + H_{2}O$

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