Explanation:

Answer:

\boxed {\boxed {\sf A. \ Chemical \ change-gas \ produced}}

Explanation:

Baking soda (NaHCO₃) and acetic acid (C₂H₄O₂) in vinegar react.

They form water (H₂O), sodium acetate (NaC₂H₃O₂), and carbon dioxide (CO₂).

This must be a chemical change, because new products are formed. We can eliminate choices B and C, because they are physical changes. Physical changes don't require a chemical composition change.

So, we are left with choices A and D.

Choice D must be incorrect because mass cannot disappear. According to the Law of Conservation of Mass, mass can't be made or destroyed.

That leaves choice A. Combining baking soda and vinegar is a chemical change, because new products, like gas, are formed. The gas helps blow up the balloon.
