I do not understand how two Al four O and two H become Al (OH) 3. How do we cut them? What did we do with them so that the index 3 appeared in the end? Can you please explain. Nowhere is this formula anywhere in Russian TH-cam. As an oxide of three-alumina aluminum (Al2O3) to turn into hydroxide.
My teacher does not explain what the chip is cut into what the cavity can not be reduced, and in her words there are nesting so I'm confused. Judging by her words and all the rules that I read there there must be out of either 2AL (O2H) or I'm a dull
I'm probably not going to be much help here as I'm not familiar with the reaction mechanism. For this decomposition reaction you do need to apply heat for it to occur. So energy is added. But as to the mechanism, and any intermediaries, I am unsure. --- Dr. B
@@wbreslyn Oh, you don`t know how the reaction goes. What are you doing in the cgemistry. Had you ever learned chemistry at some level. Eerhm it is obvious you had learned some chemistry, you can Balance, LOL LOL LOL. You dont know the mechanism LOL. Please tell me what are you talking about ?
@@Ivan-qo2ypActually, decomposition of Al(OH)3 at high temperatures (as described in the title of the video) does produce water and aluminum oxide. "Metal hydroxides: aluminum trihydroxide (ATH) and magnesium hydroxide (MDH) are the most common but aluminum oxide hydroxide (Apyral AOH by Nabaltec) is also used. Under heating, they decompose in metal oxide and water, absorbing heat, releasing vapor, and building solid residues making a barrier against oxygen and heat." From www.sciencedirect.com/topics/engineering/aluminium-trihydroxide . --- Dr. B
@@wbreslyn To put it simply its called "Decomposition of Metal Hydroxides" When a metal hydroxide undergoes thermal decomposition it will produce a metal oxide plus h2o, there are also two other types of decompositions that I know, such as Decomposition of metal carbonates, carbonates are CO3 so when we have a metal carbonate and it undergoes thermal decomposition it will produce a metal oxide and carbon dioxide. Another one is Decomposition of Metal chlorates (CLO3) it undergoes thermal decomposition and produces the metal that is found in the reactant plus oxygen (O2) also for that to happen it must have a catalyst such as MnO2 and obviously heat. I hope you understood this. I will also send you something else that I sent to someone.
Because this is a decomposition of Metal Hydroxides, when a metal hydroxide undergoes thermal decomposition it will yield a metal oxide and water. So Al(OH)3 is a metal hydroxide. Al being the metal and OH being the hydroxide, obv OH has a charge of -1 and aluminum is +3 so we just do scissors trick and that is how the 3 is there. Now when it is heated it will make a metal oxide aluminum and oxygen, aluminum is +3 and oxygen is -2. We do the scissors trick and get Al2O3 and obviously we put the H2O. That is why we then get Al(OH)3 = Al2O3 plus H2O and obviously you need to balance them. Hope I made it clear for you!

I DON`t understand, WHY!?!?!?!?!? You never say at what temperature or how. You only balance them. That is the easiest thing= YOU NEED TO HAVE EQUAL AMOUNTS OF EVERYTHING AT LEFT AND AT RIGHT. For what kind of moron is that hard? Everything i found in the internet is at the base level and under it. PLEASE TELL ME WHY????
@Meher setia the exact temperature, the type of the process- is it redox or not. If there is a catalyst, what is it if there is. Those things, they are very important for understanding the process
@Meher setia really quick guide how to balance: O is always 2,H is always 1,the others are easy to remember, the sum on the left must be equal to the sum on the right side of the equation. That`s it, it`s math with the numbers from 1 to 10
These classes are mesmerizing and magic for me.
Thank you sir.. I had a lot of problem in this one... Thanks for solving it so smoothly...!!
Hello from Russia! Thank you so much for your help!!
Glad I could help!
Thank you very much
I was struggling with the question...but it is amazing now😊
I could not understand how to balance equations . With your help I came to know that it is very easy. Thank You Very Much.
You are most welcome!
Thx. NOW I MAY DO MY HOMEWORK WITHOUT ANY DOUBTS JUST BECUZ OF U!
Thank you very much I wish you were our science teacher
You are soooooooo best teacher ever 😊😊😊
Thank you bro from INDIA ,
Thanks sir
U made it very easy
Glad to hear that!
- Dr. B
Thanks you so much!!!
No problem! --- Dr. B
Thanks a lot finally got how to do it!
Glad I could help!
You're my saviour
can you explain how is this equation balanced 3 C2H3O2H + Al(OH)3 = Al(C2H3O2)3 + 3 H2O
Thank u sir I was very confused u cleared my doubt
No problem, great to hear!
Hello from India,u remember me 😀,thanks for explaining this as I got so confused,thank you very much ❤️❤️❤️❤️❤️❤️❤️❤️❤️🌹❤️❤️🌹❤️🌹 🌹🌹🌹🌹🌹🌹🌹🌹
Thanx a lot I was very confused in this one but u cleared my doubt
he is like that indian man
a GOD TO ME
@@mexicanpango ye bro I am also indian
Thank you so much sir
Thank you very much!
Thank you sir for you knowledge
You are most welcome!
thank you very much 🎉🎉
Thank u so much 😊 you help me it.was so had and our teacher he never understand me like this way 😂 thank u so much 💖 😊
Why is the OH in the bracket?
Thanks
Thank you
You are welcome! -- Dr. B
Thank you for posting nearly every reaction. It helps much. Thank you again

Thank you sooo much Dr.B
Most welcome!

Thank you from Russia !
You are most welcome!
In class I didn't understand what teacher say but when watched video, I understand all!
Thanku sir ji
Thankyu so much
Clear explanation
Thanks!
Sir make a video for this,
NaAlO2+2H2O-Al(OH)3+3H2O
thank you!
You're welcome!
You are great

Good job 👌

My man, thank you
Any time!
hello from russia. thanks you!
Thanks a lot🌹🌹
You're welcome 😊
I've got the question why Al2O3 react with the H20, despite of it belongs to amphoteric oxides, which don't react with the water
Because this is a decomposition of Metal Hydroxides, when a metal hydroxide undergoes thermal decomposition it will yield a metal oxide and water. So Al(OH)3 is a metal hydroxide. Al being the metal and OH being the hydroxide, obv OH has a charge of -1 and aluminum is +3 so we just do scissors trick and that is how the 3 is there.

Mujhe Oxygen nahi samajh me Aaya.
Remember that the subscript 3 outside of Al(OH)3 means that you have 3 O atoms and 3 H atoms...
Wrong hai ye समीकरण
