Drew added yeast and sugar to lukewarm water and placed it in a flask. He stretched a balloon over the opening of the flask. After several minutes, he noticed small bubbles rising along the side of the flask as the balloon slowly began to inflate. How should the mass of the balloon/flask complex after the reaction relate to the mass of the balloon/flask complex before the reaction?
WHAT CANNOT BE CREATED OR DESTROYED

Clarissa is conducting an experiment. She carefully measures out 15g of baking soda into a bag. She then carefully measures out 25ml of vinegar (which is equal to 25g), pours the vinegar into the bag and immediately seals it. She then watches as bubbles start to form and the bag fills up with gas. According to the Law of Conservation of Mass, how much should the bag weigh after the reaction has finished?
WHAT IS 40G

Two students are holding each end of a jump rope and creating waves by moving it up and down. The waves travel along the rope from one end to the other. One of the students notices that when they move the rope slowly, the waves are further apart, but when they move it quickly, the waves are closer together.
What does this difference in spacing between the waves represent?
WHAT IS THE WAVELENGTH OF THE WAVES
