Jesus was conducting an experiment in science class. He took a flask and measured 50ml of vinegar into it. He then measured 10g of baking soda into a balloon and attached

the balloon to the flask, covering the mouth of the flask completely. Next, he puts the flask with the balloon attached on a triple beam balance and finds the total pre-reaction

mass of his experiment
. Finally, leaving the flask/balloon set up on the balance, he lifts the balloon and mixes the chemicals. How should the total mass be affected by the

chemical reaction? This is science
