Extremely well done explanation my brain accepted it like a sponge!
@@naafi2287 thank you, love to hear the positive feedback ..May the learning process got easen for you✨✨
Tqvm sir for this video really helps me a lot. Sir can u do pspm question for every topics, i love the way u explains
Thank you so much for the kind comment. For the PSPM questions, you can them out at the playlist videos.

I love you sir ❤❤❤❤ thank you for helping me with my assignment😊😊
@@KooopyZZ Welcome, I am happy it helps🔥🔥goodluck
Why we must minus 8 with 4 in first question?
For H2S, the total valence electron is 8. 4 is deducted because there are two bonding pairs. (1 bonding pair represents two electrons)
atom klorin punya effective nuclear charge bukan +7 ke?
Yes, you are right = 17 - 10 =+7. I made a mistake there in the video. Thank you for noticing😊
hello teacher may i ask this video is the latest stpm syllabus or not
thank you sirr
Welcome and thanks for watching☺
thankyou so much sirrrrrr✨🤍

Semoga ini dpt membantu pelajar lain tq sir haikal..👍
Thank you and betul, hopefully this can be beneficial to others! ☺️
Sir, do you have the English version? would be wonderful if there is for those who are learning solely in English alone. Like your teaching style and enjoy your lessons! Thanks, sir.
Hi Sam, thank you for the kind comment. Unfortunately, for now, CHEMIKAL series is only available in BM (mix a bit with English term). Will take that into account for future improvement.
@@SirHaikal Noted sir. All the best on your channel and Thanks!
Thank you sir❤
Most welcome, have a fun time learning😉
get well soon sir
thank you very much sir please try to use english as much as possible cuz there are international students watching
asssalam alakum sir is it wronge if i wrote the cell notation with the numbers ?
Wslm, do you mean the number of stoichiometry like 2Zn? It is not supposed to be included in cell notation. However, numbers for concentration and pressure of the species are written ✔
thanks sir
thank you
Tq sirrrrr❤
Welcome and all the best in learning☺
Faham sangatttttttttt
Alhamdulillah, TQ!☺
sir, klau nak cari Ea reverse reaction utk exothermic mcm mna? still guna formula Ea reverse = Ea forward - delta h ke?
Sir ajar faham sangat..alhamdulillah ❤
Alhamdulillah, happy to hear that😉

this video help me a lot
sir, kenapa kat eq Mg(OH)2 arrow nya equilibrium, tapi kat Mg(NO)3 arrow nya full headed ye ?
Mg (OH)2 adalah slightly soluble salt. When dissolved, the salt will be at equilibrium with ions. Jadi, pakai reversible arrow. Mg(NO)3 adalah solution, dia boleh dissociate completely to form its respective ions. Jadi, pakai forward arrow. For further explanation boleh refer sini: ua-cam.com/video/GJ_Sen-lk48/v-deo.htmlsi=IceBXoldZmdRzHZ1
thankyou sir. sir, video soalan num 6b tak ada ke ?
Welcome and thank you for watching. ☺Vid soalan 6b da available ya ua-cam.com/video/bui8qRcwrwA/v-deo.html
Thank youu sirr!
Welcome, and thank you for watching the videos!
Sir bole share cth soalan past year chemistry tak sir? Utk 1s sem
Ada, boleh tengok di playlist Chp 1..scroll bawah sekali. Akan diupdate from time to time. Ni contoh video: ua-cam.com/video/hGbrjr9Tb7c/v-deo.htmlsi=SRPZ3R4pHXmsVmCe
Thanks a thousand 😭 it is help a lot😇😇❤️
Hi sir, aroun min 16.09 bukan ke 4-cyclopropane? Mcm mana boleh jd cycloproPYL 🥺 please bg pencerahan. Tq
Hi, dia jadi 4-cyclopropyl sbb dia adalah substituent ( branch) bukan parent chain.
Sir may i know for Q8 why the mass of water =1kg？（the question didnt mention🤔🤔
We need to make an assumption. You know that molality is 10.5 mol kg^-1. So you know that for 1 kg of solvent ( H2O), moles of solute ( NaOH) is 10.5 moles. ( based on molality formula)
@@SirHaikal Thanks for ur reply，sir！❤️ other question usually assume mass of solution=100g but Q8 assume mass of solution=1kg=1000g so our assumption is based on the question？
@@Night-io2hr You can also assume mass of solvent as 100g which is 0.1kg. Therefore, you moles of solute will be 1.05 moles. If you are consistent with the assumption until the end of working, you still have the same answer; regardless you assume mass of solvent as 100g or 1000g, 10g or 1g. To conclude, assumption depends on us and ( unless the questions gave additional info) and the answer should be the same.
@@SirHaikal ok thank u sir❤️
Fahamm😊
Alhamdulillah, Good Job👍
Hello sir mcm mna nak bezakan acidic ngan basic medium tu?
Bergantung kepada soalan. Kebiasannya, soalan akan direct mention in acidic @ basic medium. Or, question can indirectly mention that “when the substance dissolve in HCl solution, “ in which this refers to the acidic medium.
@@SirHaikal ok sir tq
thank you sir
Thankyou sir, doakan saya boleh jawab chemist den ha n tenang.
Aminn, semoga dipermudahkann semuanya🤲🏻
Sir, for P, isn't secondary alcohol?
Hi yes, you are correct. It should be secondary alcohol. I may have wrongly drawn the structure.
Thank you sir 👍

baik
Hi sir, if you dont mind can you teach us how to answer boiling point and solubilty in inert solvent and h2o ? Will be more helpful, thank you sir!
sir knp guna 0.0496 mol of H2O bukan H2?
Sbb soalan minta heat released to form H2O. mole of H2 = mole of H2O since the ratio is 1:1. 10:19
@@SirHaikal ooo baik sir terima kasih
