So, I decided to do a science project using vinegar and baking soda to inflate a balloon. I blew one balloon up with my oxygen and another with the baking soda and vinegar. I would like to know why when I pop the balloon with my oxygen the balloon makes a louder sound that the one with the vinegar and baking soda?

Answer 1:

Carbon dioxide is more dense than oxygen. I can imagine that this would mean that the pressure wave from the bursting balloon might move slower if it is moving from expanding carbon dioxide, but am not sure.
