Question

I need help with these three questions for my Physics project about baking soda and vinegar

Answer 1

Here's a guess
The chem equation attached suggests to me that it is 1 molecule of acid reacting with 1 molecule of bicarb to produce 1 molecule of CO2.

for 4, I'd say that if you start off with "dry" bicarb you'll have a certain (large) number of molecules present. Adding the acid should, I think, pair off one molecule of acid with one of bicarb to give one of CO2. Until all the bicarb is used up. And then that's it, unless you add more bicarb to "replenish the stock" so to speak.
for 5 I'd say that the reactant which "ran out first" would be the one that limited the CO2 generation. Which would be either excess acid having used up all the bicarb, or excess (dry possibly) bicarb having used up all the acid (like tissue paper or blotting paper, sort of thing).
for 3 I don't really understand the question ... not the way it's worded. Isn't it a one acid to one bicarb gives one CO2 relationship ?

Answer 2

I didn't understand question 3 either but I gave my best answer, thank you for your help!~

Answer 3

@ichbinpotato giving your best is excellent. You are very welcome. I hope we're SOMEWHERE near the mark. I'm intrigued by your nickname. ich bin potato = i am a potato ? in german. Reminds me of President Kennedy "ich bin eine Berliner". how far wrong am I on that one ?

Answer 4

@osprey ahaha, It's really a joke between me and my schoolmates when I used to take German. You are right though! It does mean I am a potato :3
