Question

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.

Which conclusion is best supported by this experiment?
A Gases do not have mass.
B Gases are less dense than liquids.
o o o o
C There is no change in mass during a chemical reaction.
O
D The reactants do not change during a chemical reaction

Answer 1

Answer:

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.

Answer 2

There is no change in mass during a chemical reaction.

Law of mass conservation

The law of mass conservation states that the total mass of an isolated system is constant. Based on this law, inflow mass is equal outflow mass.

The total masses of all substance involved in a chemical reaction are same.

Mass before = Mass after

Therefore, the conclusion that can be drawn to support the experiment is, there is no change in mass during a chemical reaction.
