Baking soda is placed in a balloon. The balloon is then wrapped around the mouth of a flask that contains

vinegar. Next, the flask is put on a balance. The baking soda is mixed with the vinegar and produces a gas

that causes the balloon to expand. The reading on the balance does not change. The diagram below shows

this experiment.

Option (C)

There is no change in mass during a chemical reaction;

Explanation:

The law of mass conservation can better explain this phenomenon. According to the rule, "Energy can not be either produced, nor can it be lost."

In simpler terms, the total masses of all substance involved in a chemical reaction are same. Furthermore, the total atoms on either sides, i. e., reactant side and product side are the b.
