When baking soda is mixed with vinegar, which type of reaction has taken place?

            When baking soda is mixed with vinegar, a Neutralization reaction takes place.

Explanation:
                   The reaction of Baking sode (NaHCO₃) and Vinegar (Acetic Acid) takes place in two steps.

Step 1:
           In first step a Double Displacement Reaction takes place between baking soda and acetic acid.

               NaHCO₃  +  CH₃COOH    →    CH₃COONa  +  H₂CO₃

Step 2:
           The Carbonic acid (H₂CO₃) formed in first step undergoes Decomposition Reaction as it is unstable.

                                 H₂CO₃     →      CO₂    +    H₂O

The answer is b because c don't explain why the moths are on them and it isn't a because as we know only one species of moth does this

C) the increase in atmospheric pressure pushes the walls of the balloon outward thus making it  is the answer.hope i you.
