Question

PLEASE HELP!!!!!!!

You compare the gas generated from a reaction using two antacid tablets with the gas generated from a reaction using four antacid tablets (consider the antacid as the limiting reagent).

At constant pressure and temperature, how do the volumes of the gases compare?


The two reactions produce the same amount of gas.


The gas generated by four antacid tablets has a smaller volume.


The gas generated by two antacid tablets has a smaller volume.

Answer 1

Answer: The gas generated by two antacid tablets has a smaller volume.

Step-by-step explanation:

Since the antiacid is the limiting reagent, we know that the more tablets there are, the more gas there will be.

This means that there will be more gas generated by the four antiacid tablets when compared to the two antiacid tablets, which gives us that the gas generated by the two antiacid tablets has a smaller volume.
