Like most students, Megan really enjoyed doing labs in science class. One day her teacher allowed the class to design their own experiment. Her task was to see if she could blow up a balloon using chemicals. Megan knew that vinegar and baking soda would fizz and produce a gas. However, her teacher didn't give her any vinegar to use, only dilute hydrochloric acid. Megan thought she could use the acid in place of the vinegar.
Based on the reading above, which hypothesis would be supported by the experiment?
