The aspirin you just make both side of the equation balance of number of atom of each element.

For the question asking about which one could pressure not change did you put the one with (s) (s) in the reactants side of the equation?

How many questions can you get wrong for an 800

AA) I put A

BB) Na(s) --> Na(aq) + e+

c9h8o4 is Aspirin

The pressure answer was A… The number of particles were equal on both sides

for the pressure you might see the number of mole … if both side have equal mole then the pressure won’t affect anything

What was the one about 4 L of h2 and 3 L of o2 exploding to make h2o… Didnt answer that one

^You’re left with 1 L O2

1 L O2

I think i got it wrong. I put 2L of O2…it was either that or 1 L of O2

Wow… Just realized I balance that equation wrong and that im a complete idiot…

Guys Dont Sweat it… Its just 1 question

Equation representing ionization NRG?

what did you guys answer for the highest pH, in part A

@redrabbit23 Can you elaborate?

I put BaOH for highest ph…if thats what ur asking

Is it because of a strong base? so higher pH?

Yes @dopefresh

For the one with the highest concentration of H+ was it like whichever one had the highest pH so you needed to look for the number with the lowest exponent in __ * 10 ^ -x where x needed to be small? I think it was A that had the highest concentration of H+
