How to study for chem the next three days help (1 Viewer)

[=)(=]

wait this might be dumb but at equilibrium will HOCl always have the same concentration as OH-?

@carrotsss @Masaken pls help
For the first one i feel like i had the same method as the hsc but i dont know where i stuffed up???

.

 

[Masaken]

wtf stop being so smart


anyways where did i go wrong for the first one

if NaOH is limiting then that means when you're doing the thing where you're calculating the number of strontium nitrate moles reacted 0.12 - 1/2 x (0.0684) you're actually calculating how much was in excess or am i tripping

i'll do the q again i can't find my hsc paper it's in my bag somewhere i'm not bothered to get it out rn

no, when you calculate it, you'll see they have different concentrations it's given that [HOCl] = 1.3 x 10^-4. when you calculate hydroxide [OH-] = 10^-6.5 so they're pretty diff

Bruh that’s such a dumb mistake then
Would I get 3/5 cus I think the rest of the process is correct?

So like I basically forgot to account for the excess strontium or what I’m not too sure what I missed yet

i'll look at it again later cos even tho i knew how to do it yesterday i'm struggling to see what else is going on sorry

you assumed that the aqueous concentrations would be exactly the molar ratio but they’re not, the one in excess has higher concentrations and the other one has lower conc

So I basically forgot to add the excess miles?

I think so

miles?

 

[SadCeliac]

miles?

morales?

 

[synthesisFR]

I don’t get it bruh

im prepared!!!

this guy gives me a long ass speech to not give up and look at him
