3. A student was adding baking soda and vinegar in a bottle to conduct an experiment. They then put a balloon on top of the bottle immediately after adding them together. The student observed that the balloon inflated and got larger. The student then predicted that the chemical reaction between the vinegar and the baking soda had created brand new matter, and would have more mass at the end of the reaction. Would you agree with the student’s prediction or not? Explain your answer.
My answer is
Type Answer HERE: No I would not agree with the student that new matter was created during the chemical reaction between the baking soda and vinegar, because a chemical reaction needs equal mass of reactants and mass of the products. So in this instance the balloon inflated because of carbon dioxide not because of a new matter that was created durning the chemical reaction. Am I correct?
