a flask with vinegar in it has a mass of 160 grams. a balloon with baking soda in it has a mass of 40 grams. the balloon is attached to the flask to seal the opening and the vinegar and baking soda mixes. the balloon inflates to a large volume. what will the total mass of the balloon and flask be after the balloon inflates? explain.\na less than 200 grams because the solid baking soda disappears.\nb 200 grams, because all the atoms remain in the balloon or flask.\nc more than 200 grams because the size of the balloon is so much larger.\nd less than 200 grams because gases such as the one in the balloon are lighter than solids and liquids.

Answer

Brief Explanations:

According to the law of conservation of mass, in a closed - system (the flask and balloon here), the total mass before and after a chemical reaction remains the same. The initial mass is the sum of the mass of the flask with vinegar ($160$ g) and the mass of the balloon with baking soda ($40$ g), which is $160 + 40=200$ g. The disappearance of solid baking soda is due to a chemical reaction, but the atoms are still within the closed - system. The size of the balloon or the state of matter (gas being lighter per unit volume) does not affect the total mass.

Answer:

B. 200 grams, because all the atoms remain in the balloon or flask.
