Very useful sir thanks 🙏🏻
Sir, I am ishan and Sir. It is a qualitative video and video in which there is no wastage of time
@@munish6711 thank you ishaan Glad you liked it ☺️
Nice
Nice
Thanks 😊
Waah sir...kya explain kiya
💯👍👍
Great Sir
Thank you Aman ☺️
Al+H2O =?
Aluminum when react with steam forms aluminum oxide and hydrogen gas
Sir mujha product bananaa nahi aata tha aapki Kripa sa mujha nikalna aa gaya thank you
Sir ye m dhoond dhoond k thak gaya tha Aapne bata diya Thanks ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
SIR VERY THANK YOU MAI 10 DIN SE YE EQUATION NHI SMJH PA RAHI THI AAPNR YE VID DAALKE BOGOT HELP KARI HAI THANK YOU SO MUCHH
🙏🏻
Thank You
You're welcome
Good
Much needed lecture
👍🏻
👍
👍👍

Sir maza aa gaya , sab samajh aa gaya😊
Awesome sir ❤❤❤
Thank you 🙏
Calcium react with water and produce hydrogen gas which is adsorbed on the surface of calcium that' why calcium float in water
correct
❤🔥
Thank you sir 🥺
Always welcome
Rehen do bhaiya apse teaching na ho payega. Is equation me lhs side me gas hone ke wajah se ye oxide form karega or h2 jaisa tha waisa hi rahega
🙏 ok mam
Sir iron ki valency 2 or 3 kaise samghe kya le
Video dekho
Properly
👍👍♥️😊
Dear sir, I'll used this method Zn + H2SO4---> znso4 + h2 Zn(2, 8,18,2) ab isko nishkriy hone ke liye ya to 6 etoms chaiye ya to 2 ko de denga, And So4 ( -2 ) Zn ✖ So4 ----> Znso4 + h2
Being a metal its very hard ki ye kisi se electron le so iski valency 6 toh nhi hogi ,but Since it got 2 electrons as you have mentioned its valency is 2 Par ye method iron kai liye sayad work krega as Fe is 2,8,14,2 Aur iron wala case samajhne kai liye hame higher classes ki books 📕 padeni padegi😃
@@Chemenigma sir me higher class me hi hoon bas sir ye ek samjhado to bohot help ho jayegi meri please sir... 🥺❤✨
Iron ki configuration Fe= [Ar] 3d6 4s2 Fe2+ = [Ar] 3d6 4s0 Fe3+ = [Ar] 3d5 4s0 Fe having half filled 3d in +3 os so it will be more stable than fe2+
Fe3+ is more stable than Fe2+ due to its half filled configuration therefore some amount of FeO( again not all FeO ) gets converted into Fe2O3 thus we got both products which is a mixture FeO.Fe2O3
Thanks bro you clear my dout
Glad to hear that
What is the reason to multiply 3
Just to show that there will be 3feo formed in the first part but only 2of them will converted into fe2o3

Haan ji pauri garhwal

sir mahine se samjne ki koshish kar raha tha MASHALLAH SE ap nai itna pyara samjhaya ALLAH ap jaise teachers ko khush rakhe
thank you ji
Tq so much sir it helped me a lottt💛
Most welcome 😊
You said that the lobes give tetrahedral geometry but the books say that NH3 shows pyramidal geometry ??
There is a little issue in your statement Nh3 have a tetrahedral geometry this is absolutely correct . Nh3 have a pyramidal shape that is also correct But thete is a difference in geometry and shape Geometry(also known as electronic geometry ) is determined by the combination of both bond pair and lone pair while Shape (also known as molecular geometry) is determined only on the basis of bond pairs😊
@@Chemenigma oh I did not know that thanks a lot. You were really helpful 😁
Ha bhai
I wanna ask we connected the chlorine atoms with brellium on X-axis I tried to draw it and did it on Z-axis As the empty orbital is Z Is that right I didn't understand the language that much but tried
Dear student , Generally we do the intermixing of orbital along z axis so bond formation will takes place with pz orbital of chlorine , If you are considering the intermixing along x axis then bond formation will takes place with px of chlorine atom Similarly you are considering the intermixing along y axis then bond formation will takes place with py of chlorine atom
@@Chemenigma Aha got it thanks

Wow sir please upload regular video. Now I think that I got you that is very amazing channel 🥰 bahut achha samjhaya thanku sir mera doubt clear ho gaya aasani se
Thank you ❤️ , suggest any topic you want i will upload it soon.
Sir ek confusion h plz ap help kar de sir actually m uss baat p confused hu k ground state kis k nikalnii h Nh3 ap n liye tu sir N k kU ??? mujE aaghi pora samjh aa gaya sir plz y thore confusion clear kar de
Hybridisation hamesha central atom ki nikali jati hai , aur ammonia (NH3) molecule mai central atom N hai, isiliye yaha N Ki ground state li hai
Clear?
Thank u so mucH ❣️
Sir aap to duniya ke mhan teachers hai......🙏🙏🙏🙏🙏🙏🙏
aisa bhi nhi hai dost , thank you🙏🙏
Op video sir🛐🛐
Thank you🙂
Sir why in rusting Fe2O3 is formed not Fe3O4 is formed Plz sir plz reply and solve my doubt. 🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼
Good question , the answer is during rusting fe first convert into fe2+ ion then immediately oxidises by Oxygen into fe3+ ion so there in the final product ,we only have fe2o3 and neglegible feO thus fe3o4 not formed during rusting
Please make a video on organic chemistry reaction mechanisms concepts.
Thanks for suggestions but there are plenty of reaction from which you wanna begin?
👌
😃
Thanku sir , I have struggled a lot to find a video like this on RUclips , and here I got....
