Answer:

Explanation:The most famous supercontinent had a good run, though — Pangaea didn’t really start to break up until the Early-Middle Jurassic Period (175 million years ago).

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

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.
