A teacher performed a demonstration of a chemical reaction by stretching a ballon containing Sodium bicarbonate (baking soda) over the top of a flask containing acetic acid (vinegar). When the sodium bicarbonate was added to the acetic acids the ballon began to inflate shown I'm the figure. What will the total mass of the flask, the ballon, and products be after the reaction?
A. Less than 100g, because some of the solid baking soda disappears
B. 100g, because all of the atoms of the reactants remain in the flask
C. Less than 100g, because the gas has less mass than the solids and liquids
D. 100g, because the volume of gas inside the balloon has increased​

Explanation:

D. 100g, because the volume of gas inside the balloon has increased​

In chemical reactions that occurs in closed systems, the amount of matter is conserved. The total mass of the system is conserved because the gas did not escape and the volume has increased,

d

Explanation:

that's just how they are

explanation:

you can't control another persons decisions, all you can do is ask that they respect yours. relationships are hard because you have to put the effort into making sure that another person feels seen, heard, and loved. as time goes on, it gets easier, you learn how to do these things without thinking. loving them becomes as easy as breathing, but every relationship will have fights, and sometimes it'll feel like you're drowning, but as long as you can talk it out and compromise, because that's truly what loving another person is, is compromise, then you'll be okay. movies and tv shows have glamorized and romanticized (pardon the pun) what a relationship would be like. real relationships aren't perfectly timed kisses in the rain, zero fights until one big one ends everything, 6 month anniversaries. real relationships are sleepy confused kisses when one person has to leave for work earlier than the other,   real relationships are having small disagreements, real relationships are messy and confusing, real relationships is knowing that even if you're relationship may not last forever and this may not be the person you're going to spend the rest of your life with, that you love them, and you would do anything to see them happy. so yes, relationships are difficult, but so are many other things, relationships can be amazing but also stressful, and not just romantic i'm also talking about platonic relationships (although the primary example here was romantic) sometimes is best to leave friendships behind, so remember, always do whats going to you be happy in the long run.

i believe you are right for all except the 3rd ( look at sqdancefan his answer is much better)
