sir u said that there are 8 fcc unit cell combined to form a single unit cell of spinel and in each fcc unit cell only one tetrahedral occupied but in picture there are 2 tetrahedral sites are developing in per fcc unit cell of spinel unit cell and the other remain empty i dont understand this one
It is actually average. There are two types of sub unit cells. In one sub unit cell there are two tetrahedral voids occupied. next one is empty. That means on average each cell has one tetrhedral void occupied.
sir plz explain my some problem.. if u hv some time, i will be highly obliged to you What will the Vrms of the gas if the temperature of a gas is raised from 27^C to 927^C?
Aditya vardhan V AdiChemistry thnkk u so mch sir...nw i feel chemistry problems r now no more problems.. scarcity of money n coaching will not demotivate me anymore..thnk u so mch sir 4 replying soon..thnk u sirr☺☺☺
Since it is inverse spinel, the unit cell consists of 8 sub unitcells. There are 32 oxide ions and 8+16 = 24 iron ions - both Fe(II) & Fe(III) . Hence the mass comes to 1852 amu. It is simply 8 times of formula weight of Fe3O4. You can get more idea from: www.adichemistry.com/inorganic/cochem/spinels/spinel-structures.html
Nice to see your comment. It seems you too are pondered over the crystal structure of spinels. actually this video is the outcome of almost 6 months careful searching and modelling.
Nice presentation easily understandable but Pronunciation errors of some words is little disturbing. (I dont want to accustomed with wrong pronunciation sir, Sorry) Thank you for the nice lecture really helped me to understand.
ok. I got it. You want to know the volume of unit lattice of spinel. I will give you the idea. Never tried. Let me try in the leisure time. Keep patience.
Co3+ is smaller one with greater charge density such that it makes oxide a strong field ligand. And the dications belong to either main group or d10. Now I hope you can workout.
@@AdiChemAdi What does that even mean? I mean, I can't say "oh, it's called what, I don't like that, let's just say whutty". I mean, language gives strict and exact rules and it's not about personal preference which ones to stick to!
Thank you. It is how and what I like to pronounce and I will try to change. Yes there are rules. And they will change when you move from north to south or east to west. Like you have english usa and english uk. So it is english by me. And I never said I am not going to change my pronunciation. My mother tongue is not English. You should understand it.
@@AdiChemAdi I understand your accent and I never said you wouldn't change, I just said that "that's the way I like to pronounce a word" (wrong by purpose) is not an option. And yeah, English is a variable language when you look at the geographical relation, but dude, noone says yight. What is that? That sounds more like a disease...
ok. But to be honest, it is truly how I would like to pronounce. And I think most in our area too pronounce in the same way. So may be I got it from them. I am surprised to know that it is a disease.
I bet u cant even pronounce better so that Native english people will understand it.... some stop complaining about the pronunciation... think like ----- some one from south india is speaking english with their accent....u will get it bro..........easy peasy..............:) LOL
Ok. No problems. All of us have to go through same phase at some point of life. But we have to learn how to be silent and peaceful to achieve our goals. All the best.

Superb presentation... It clear many confusion.. thank u sir
You are welcome. Glad it helped you.
Sir Nice Presentation and Perfectly Explained 🙏🙏🙏 Thank You Sir. Ignore these Critics of your pronounciation. You're doing wonderful Sir 💐
Welcome. Thanks a lot. I am not God and their criticism will remind me the same.
Sir I would like to ask why the A ion occupy 1/8 tetrahedral void but the B ion occupy 1/2 octahedral void , thanks🙏🙏
It is the formula that decides this ratio. Just swap the positions....you will get different formula
Also Watch th-cam.com/video/JvgX-QNc8gU/w-d-xo.html for activation energy
Nice explanation.plz upload more video.
sure
Helped alot in visualization.. Thank you sir!
Glad it helped!
Very good presentation Thank you very much sir
nice to hear from you. thanks.
Mama u seriously rocked it. BTW where is the part 2 link... I cant find it in your channel. :)
Thank you.... The link for second part is th-cam.com/video/K1DXFEwoxdU/w-d-xo.html

Sir Can you upload trick videos for inorganic chemistry
yes. sure. I think you are asking for M-M bonding, cluster type formula, styx number......?
Yes sir
ok. pls. wait.

Sir, Please Explain the post spinels st.
already I have uploaded the 2nd part.
sir plz explain my some problem.. if u hv some time, i will be highly obliged to you
What will the Vrms of the gas if the temperature of a gas is raised from 27^C to 927^C?
hint: rms velocity prop. to square root of T (absolute tem)
Aditya vardhan V AdiChemistry sir it will be doubled or halved????? And how????
V2/V1 = sq.rt(1200/300)=sq.rt(4) = 2
How can it be halved, velocity increases with temperature.

Also plz upload organic reaction mechanism
sure.
Thank you for this video.
My pleasure!
Sir how to explain electro neutrality principle in coordinated complexes
sorry. I could not follow
Sir please upload video for how to determine exact structure for coordination 8 ,9,10 and there point group
Exact structures are found experimentally. They differ in different conditions too. Like temperature, solid or liquid etc.
What is the volume strength of 1.5N hydrogen peroxide???
shortcut is multiply with 5.6.
Aditya vardhan V AdiChemistry please elaborate
Can You Please Tell Me The Molecular weight of Fe3O4 per unit cell!
molecular weight per unit cell? What do you mean by that?
@@AdiChemAdi No Of atoms of fe and O Weight In a Unit cell of Fe3O4 Combined
@@AdiChemAdi Or You Can Say A Unit Cell Of Fe3O4 Made By Fe and O Atoms So I Want To Know the atomic mass Of Fe3O4 of one unit cell!

What is the volume strength of 1.5N H2O2
Sir please explain its answer plzzz
1N solution gives 5.6 L dioxygen. 1.5 N gives 1.5 x 5.6 L of dioxygen.
Aditya vardhan V AdiChemistry what is the link with oxygen from strength😢😢
1 mole H2O2 gives half mole of dioxygen. you know 1 mole of H2O2 is 2 equiv. or 2 N solution. so 1 N solution gives 1/4 moles of dioxygen or 5.6 L.
Thank u very much sir ❤️...my all doubts are cleared .. thank u sir 😃😃😃 sir your teaching style is nice🤩🤩🤩🤩🤩

(I dont want to accustomed with wrong pronunciation sir, Sorry)
Thank you for the nice lecture really helped me to understand.
Thank you. Could you please tell me the words that were not pronounced correctly?
Dear sir
8 and Spinel were the two word distracting me.
ok. Actually spinel must be spinel not sp"ai"nel. But what about 8....? Am I quick to pronounce it? Or.......?
@@AdiChemAdi you're pronouncing 8 Yate, while it should just be pronounced ate
How to find the volume of one unit cubic? Thank you
volume is length x breadth x height. For a cube all of these are same. hence just take the cube of length.
@@AdiChemAdi thank you, but how can i measure the cube length? What atomic radius should I use?
It depends on the arrangement of atoms in the cube. If it is simple cubic arrangement, then the length of side of a cube is twice of radius of atom.
@@AdiChemAdi yes i understand that much, i mean how to measure the spinel volume, which ion radius should I use as a length? Thank you again.
ok. I got it. You want to know the volume of unit lattice of spinel. I will give you the idea. Never tried. Let me try in the leisure time. Keep patience.
Thanks very helpfull
Glad it helped
The details are really very helpful... Thanks ☺️
Thank you.
Thank you, sir! This cleared a lot of confusion!
Glad it helped!
Where is its part 2 can anybody give me the link
Will be posted sooner. Please visit: www.adichemistry.com/inorganic/cochem/spinels/spinel-structures.html for the verbatim.
Thank you so much sir😊😊😊
welcome. thank you.
can anyone solve about NiCo2O4, MgCo2O4 and ZnCo2O4
Co3+ is smaller one with greater charge density such that it makes oxide a strong field ligand. And the dications belong to either main group or d10. Now I hope you can workout.
Thank you sir
welcome
thanku sir
thank you. you are most welcome
Solve MgAl2O4
The name "spinel" was given to this compound only.
