I searched it up and it has the number of moles of acid equals the number of moles of base.
the number of moles of h2so4 equals the number of moles of naoh. they said thats the answer
No its not
Equal moles of H+ and OH- is the answer
but OH and H didn’t have the same # of moles
Yes they did, note that M stands for molars (moles/liters) if you multiplied the value of the molars by the value of the ml (and account for H2SO4 producing 2 moles of H+) the result is that there is the same number of moles of H+ and OH
It is not that because if you search up the chemical equation only one mole of H2SO4 is needed and two moles of NaOH would be needed
why wasn’t it the same # of moles of h2so4 and the base that they gave (I forgot what the base was)
Because (if that base only had one hydroxide ion) there would need to be two of that base per H2SO4 (which produces 2 H+ ions) to produce the water for the neutralization reaction (note that a neutralization reaction results in a salt and water)
If you look up the example I gave above, there is clearly not the same number of moles of acid and base
ohh. and was chlorine a gas
Yes, it was
@Fibbonachi10 do u think they are going to take off points if u didn’t put the negative for the MCAT question because they implied that energy was being released already
Towards the end, the bromethyl blue turned yellow right?
for chlorine if i wrote gas/vapor do you think i will get it right
- They may take points off if you didn't indicate that the result was negative, however am not certain
- The bromethyl blue turned yellow
- You probably won't lose points, but in the future it would be safer to put one or the other (as either one would be accepted)
just wanted to let everyone know that the website kent chemistry started uploading answers
Thanks Ben, they’re on question 10 right now.
so far 9 out of 10 right
First 15 right…
