I am neet aspirant..... My chemistry preparing is fantastic with respected, arvind sir.... Meri English bhi bhut kamjor hai but chemistry is enjoying subject.... Becoz of arvind sir...... Thanks a lot sir
In my life I have never seen a teacher like uh your style of teaching is really very amazing i am in class 12th love from Kashmir sirr thanks a lot sir
Thank you very much sir Finally aaj mai ny chemistry ka saara syllabus complete kiya aur yeh sab aap ke wajh sy possible hopaya aap k padhany ka tareeqa bohot acha hai. I'm very thankful to you. 🙏🙏🙏🙏🙏🙏
Sir Ur teaching is awesome 👌👌 and u make concepts crystal clear to us but I want to suggest something to you that u should not use abusive language in class
Copper matte is actually a mixture of Cu2S and FeS .. It's just when it is bessemerised its FeS oxidises to FeO...So..it is not Cu2S and FeO ... Please verify Sir..
Sir I am JEE asprint but I am whole chemistry completed Mr. Arvind Arora sir he is the best teacher.Thanks sir
I'm also Jee asprint and I also do same as you
Thanks sir
@@nehapawar9934 JEE ka exam kab Doge 2020 me ya 2021 ?
Why u ask this question from me
@@nehapawar9934 I would to know that ki kitane log 2020 me JEE Dene wale hai Jo arvind sir se padate hai
Yes I will
Lacture start at 4:00
Save your time 👍🏻
but i will waste 0.5 sec to like your comment
❣️❣️
59:47 copper matte comprises of Cu2S and FeS and not Cu2S+FeO
Yes 👍🏻
Yes , but iska rxn ky hoga ??
Yes sir
But we can say that Cu2S+ FeS + small amount of FeO.. Then it's not wrong..
Sir I finally completed metallurgy because of u thanks u soo much sir 🙏🙏
20:27 ALERT matte of copper is Cu2S+FeS with some impurities. I unfortunately made this mistake in exam and i hope u don't
Sir said silica with Cu2S + FeS is matte ....silica is impurity....
But thanks you soo much ☺️☺️
Ya thts right

Helo sir i want to extract copper from copper sulphate liquid solution, how can it get it easily
Sir aapne matte ka formula galat bataya hai
Cu2s+FeS hota hai
Ncert has given that mixture of coper sulphide and iron sulphide is known as copper matte.
Sab sahe he
@@quick6175 agar neet mai aya toh cu2S and FeS hi likhna padega
Sr I am a iit aspirant but I m completing my metallury by your help because I understand your study is benefical for 12th boards .
I am neet aspirant..... My chemistry preparing is fantastic with respected, arvind sir.... Meri English bhi bhut kamjor hai but chemistry is enjoying subject.... Becoz of arvind sir...... Thanks a lot sir
siir textbook me likha hai ki copper matte contains fes and cu2s
Which book do u follow for theory . Ncert?
In my life I have never seen a teacher like uh your style of teaching is really very amazing i am in class 12th love from Kashmir sirr thanks a lot sir
Composition of matte of copper is copper sulphide and iron sulphide right? But aapne kahe ki,iron oxide
Yess i also have same doubt
TODAY I COMPLETED METALLURGY CHAPTER BY THE BEST TEACHING METHOD OF ARVIND SIR. . THANK U VERY MUCH SIR
Its so boaring to hear the unwanted names of others
Not boring, it makes me irritating XD
Pad mtlb
U make a metallurgy easy .Thank you so much sir
Thank you very much sir
Finally aaj mai ny chemistry ka saara syllabus complete kiya aur yeh sab aap ke wajh sy possible hopaya aap k padhany ka tareeqa bohot acha hai.
I'm very thankful to you.
🙏🙏🙏🙏🙏🙏
Sir plz upload PDF of this session....☺️☺️
SIR COPPER MATTE CONSTITUTES OF Cu2S andFeS..PLEASE PAY ATTENTION TO THAT...CONTENT FROM NCERT..
Yeah right
Yes right. Sir plzz check and teach.
Yess sir..Cu matte is Cu2S+FeS
Agar ye log asa padhange to socho hum logo ka kya hoga😶😶
Yah right👀
Chalcopyrite: CuFeS2
Chalcocite: Cu2S
Malachite green:CuCO3.Cu(OH)2
Azurite blue:2CuCO3.Cu(OH)2
*Thanks Dear Sir fOr tremendous efforts & knOwleadge SeSsiOn* 💜
*Finally Cls 12th Syllabus Completed hip hip hurrah* !!!🙆 *Next Chaptr Start - GOC pls* !

Hi
Ye hulkat jab dhekho har ek cmmnt pe hoti hai...vahiyat thobda
@@soyabKhan-xk7sd kisko bol rhe ho
Saw all lectures spent usefull time
Matte of copper = Cu2S+FeS ☺☺☺☺
😅😅
Arvind arora teacher is the best techer thenks sir
Shukria guru g 🙏🌹❤️
VERY NICE SIR YOU ARE TEACHING GREAT LOVE YOU@
Thanks a lot sir finally i completed my metallurgy chapter 🙏☺️💖
Chalcopyrite : CuFeS2 [used as ore]
Chalcocite : Cu2S
Malachite green : CuCO3.Cu(OH)2
Azurite : 2CuCO3.Cu(OH)2
Copper is mainly extracted from its sulphide form.
Steps : Pulverisation
Concentration
Roasting(metal oxide)
Smelting(metal)
Refining(pure metal)
FeO+SiO2 --- FeSiO3 (slag)
Cu2S + FeS is known as Matte of copper
Matte --Bessemerization-- Blister Copper
Cu2S+O2 gives Cu2O+SO2
Cu2O+Cu2S gives Cu+SO2
FeS+O2 gives FeO+SO2
FeO+SiO3 gives FeSiO3 (slag)
Sir bhut ashe c smj a gea 😊
Struggling in blast furnace finally done thanku...n so useful 🙏🙏🙏🙏🙏
Thanku sir for making this chapter easy for us 🥺🥰
Matte copper is
Cu2S and FeS
Not
Cu2S and FeO
Yesss..
Awesome lecture
Thank you so much sir
😊😊👏👏👏😊😊
You are best Teacher for chemistry subject
Thanks a lot sir 🙏🙏🤗🤗🤗🤗🤗😊
really awesome explanations and full of energy ....❤❤❤❤❤👌👌👌👌👌👌👌👌👌👌👌👌
Thank u for make easy metallurgy
Sir Ur teaching is awesome 👌👌 and u make concepts crystal clear to us but I want to suggest something to you that u should not use abusive language in class
Thank you so much sir
You are amazing and very nicely teach all concept .
Thank you sir😊😊
S block
Sir matte of copper is Cu2S +FeS.... N
Yes 🙂
Yes
Chalcopyrite.... CuFeS2
@16:30 Wow !! The girl in starting was right. The teachers repeat when you have a doubt .
Sir ab aapke padhne ka style thoda tapori wala ho gaya hai , but maza aata hai sir aapse se padhne me ...thanks of lot sir...😍😍
Instead of taking copper pyrate we can easily take copper glance and once heating is enough......................
sir chemistry in every day life ka lecture upload kar dije please sir
Sir....... please make a video on hydrometallurgy topic 🙏
Sir i am From Pakistan And I swear Love the Way U Teach Us Really Appreciate Again Love u Sir ❤️
Thank you sir very much
48:21 melting point toh na3alf6 lower kerta h naa
Sir but Copper Matte is the mixture of copper sulphide (Cu2S) and some iron sulphide (FeS).
Really nice video sir
Lovely teaching sir
Sir,I'm really very thankful to you for this video
Thanks a lot sir ji 🙏 mza aagya
By 14:48 dance by Arvind sir was osmmmmmm"😘😘😘😘😘😘😘😘😘

Chalcopyrite cuFeS2
Chalcolite Cu2S
18:26 Is it Blast furnace or reverberatory furnace for copper smelting
Blast 💥💣
Copper matte is actually a mixture of Cu2S and FeS .. It's just when it is bessemerised its FeS oxidises to FeO...So..it is not Cu2S and FeO ... Please verify Sir..
Thank you so much sir for the section
Sir plz screen shot lene k lea time dea kige
Yo yo yo guys 🤣🤣🤣😂😂

Q no. 11: a molten mixture of Al2o3 and Na3AlF6
That already oxidised during Rostong....Is not it????
Sir,if possible please tell me "do bonded electrons revolve around nucleus or not"
Are You sure that Matte is Cuprous sulphide + Ferrous oxide??
I learnt that its Cuprous sulphide + Ferrous Sulphide.
Hat's off to u sir....💯👌
Thanks a lot, really helping a lot
Thank you sir👍🙏🙏👍👍👍👍🙏🙏🙏🙏🙏❤️
during smelting from where FeS come???
Matte is the mixture of Cu2S + FeS not FeO please check
YOU ARE BEST TEACHER SIR JI OF CHEMISTRY
Sr ye last lec hai kya
Plz can someone suggest me a really good book for chemistry numericals , for physical part

Question no 3 ka explanation wrong h CaF2 ka km melting point km krna Apne nhi bhtaya tha... Apne cryolite ka ye km btaye the ki mp ko km krta h
Matte of Cu, Cu2S +FeS
FeS and cu2s called matte
Sir when you teach live on vendantu
where is the pdf for last 2 sessions ?
Sir PDF ???????
