IB Chemistry Stoichiometry Revision Workshop HL/SL (Topic 1/11)

[@microgalaxy21]

This is literally AMAZING! You just saved another student suffering from IB chem. Thank you so much for making this video, and hope you keep continuing with this series. :)

[@aaria.shinoj6684]

hey! is this for grade 11?

[@microgalaxy21]

@@aaria.shinoj6684 Yes, if you are following an American curriculum.

[@Think_Legacy]

right at 35:30, shouldn't the mass of aluminium be 26.98?

[@beasea761]

at 35:28 i think you took Aluminum's molar mass as 22.99, when you should have taken it as 26.98 right? Since 22.99 is sodiums molar mass

[@ChemJungle]

:( I think I need to remake/delete this one!

@@ChemJunglenooo don’t worry!!! it’s not a big mistake

[@bdhsh2425]

That's a great video! Everything is so well explained and I understood it all. However, at 38:43 the video skipped to the ideal gas law section and it did not finish exercises 11 and 12. I am not sure if it is a glitch or if it was done on purpose but I would really like to see the rest of those exercises. Aside from this, I am truly thankful for this video and I love this type of format of revision videos.

[@wendy3182]

she made an error with the molar mass of Cu2S and I think she replied in someone's comment below that she's cutting it our until she has time to fix it

[@bara8786]

you are a lifesaver! I have been struggling with Stoichiometry so much and I never really understood how to do the calculations but your video helped me to understand thank you for creating it :)

[@ChemJungle]

Happy to help! I'm going to do the rest of the IB topics in August/Sept :)

[@dalyaaaaaa5]

Hello, this is amazing however, in min 35:20 the molar mass of Al is 26.98 not 22.99

[@maxbartsch9862]

thank you so much for just taking the time to explain everything at a good pace and also doing a question section in the video it helped me so much!! i have my finals next year may and i will definitely do good with your videos!

[@ChemJungle]

Glad it was helpful!

[@beepbobeep4594]

The fact that the “next year May” is in 2 days now. How are you feeling 😭😭

THANKYOU SO SO MUCH

[@ChemJungle]

Good luck!!

[@mayanour2394]

Oh darling, bless you. Your explanation is really understandable which is rare those days when it comes to chemistry. I have a test tomorrow and was stressed out but I am less stressed out now that I revised the basic fundamentals that I had trouble with. Thanks, dear and please keep doing what you are doing because it is helpful and kind ❤️

[@ChemJungle]

Glad it was helpful!

[@desmonddavidge6322]

Thank you! please do keep going with this revision series, incredibly helpful! I already know i'm going to be coming back to this video for exam season next year.

[@ChemJungle]

That's the plan! This was a trial run to make a couple and I'll be making more in August for the rest of the syllabus :) Any other feedback definitely appreciated!

[@ilikecookies608]

When are you going to upload the rest of the topics revision?@@ChemJungle

[@ChemJungle]

@@ilikecookies608 I'm running online group workshops for the rest of the topics and focusing on tuition at the moment. All information is on Instagram @chem.jungle

[@ahlamerfani1687]

This is amazing! Please make videos for the rest of the syllabus your teaching style is amazing :)

[@kaeyaaaa]

I love this video so much and the drawings in the last question actually made it so much more understandable thankk uu i love you

[@diyachoksey2005]

Please make more of this series if you can! You somehow make it all look so easy:)

[@MashupKingMusic]

Agreed!

[@haziqamsyaaar]

this kind of videos do help me to increase my understanding. i hope there are more videos like this. can u do revision for bonding topic ? looking forward for it ! really am!

[@eleoramichelo]

at 34:45, shouldn't the number of moles of Al_2(SO_4)_3 be 0.600? I thought you divided by the coefficient just to find which one is limiting. Does it affect the number of moles?

[@kaeyaaaa]

this might be too late but to find the number of moles that actually react u can just use the proportion so 2/x = 3/0.6 we know that since h2so4 is the limiting reactant all of it is reacting so we take 0.6 in the denominator but since AlOH is not the limiting reactant we take it as x to find the actual product that reacts

[@saraamir896]

Please do more of these revision videos!!!!

[@zp_suki2836]

THANK YOU SO MUCH!! I understood the concepts but struggled during Paper 1 and 2, I now understand what I was doing wrong ❤

[@olgaj6537]

Thank you! Great revision. Would it be possible to make a Bonding review? (T4 IB):)

[@ChemJungle]

Thanks for the feedback! I'm making an Energetics video this week but maybe Bonding next week... Last week I asked on Instagram @chem.jungle to see what people wanted and Energetics came out on top!

[@zeyroxfn9195]

43:32 don't u change dm^3 to m^3 for volume?.... So it would be 0.0000785m^3

[@ayushthaker6882]

pls make videos like this for all chapters - very nice video

[@richapandey2099]

Dear madam,i really liked your style of teaching..it's very easy to understand the stoichiometric concept.

[@ChemJungle]

It's my pleasure

[@siyaagrawal1719]

the mass of Al2(SO4)3 is 342.17 for me and then when i multiply it by 0.2, i get 68.434

[@franko_henderkin1235]

Question 11 a is incorrect the Mr of Cu2S is 159.17. You forgot to add another Cu as there are 2.

[@ChemJungle]

Thanks so much for letting me know! I just got back to this channel after having a baby and have removed this question for now until I can fix it :)

[@bharatmadho3742]

Thank you SOOO much! this is the best revision video ever!

You are awesome and your expression is very eloquent and understandable please keep making videos. pleaseeeee.

Thank you so much!

[@Rhefrigerator]

Hi! Thanks for such a helpful video. Just wondering why does it cut off abruptly on the limiting regent question (Q11) and jump to ideal gas law (Q13) ?

[@ChemJungle]

Hey Rheannah! I made a mistake with the relative molecular mass with one of the questions so I chopped it out.... my laptop died and I lost the original footage but I hope to fix it and upload a new (complete!) video sometime!

[@Vicky-pm5pw]

Could you please explain why the molar mass for Al is 22.99 * 2 in the limiting reagent question asking for the mass of Al2(SO4)3? Is it the molar mass for one Al 26.982 or did I make a mistake. I cannot find 22.99
