Science -Change

today for science, we did an experiment and we had to make a hypothesis (guess) what will happen if you put 1/3 part of vinegar in a bottle, and put 2tablespoons of baking soda, then cover it up quickly with a cork. This is my guess.


What do you think will happen?



It's gonna to form foam and will fizz, and the cork will fly away





What do you think these will be?
Reactants
Vinegar, baking soda, bottle
Product
Turns to gas (carbon dioxide)
Chemical Reaction
It's gonna to form foam and will fizz, and the cork will fly away




Was your hypothesis right/ wrong? Why?
Yes because the cork popped when the foam reached It.
