Sir My basin pipe have concrete stuck in it during construction I poked little hole in it but it will eventually clocked in future Pls tell how to remove this concrete using chemistry Pipe is made of PVC Cant use hydrochloric acid 😅
Sir we did this in our school science exhibition...... For this experiment we took baking soda,aluminum foil and glass bottle. We used an balloon to cover the top and to show that hydrogen gas blow the balloon and to check we took a candle near the bottle and it burned with a pop sound it was to much fun to do so. Our principal was scared when we took a burning candle near the hydrogen gas because It poped with a large sound😂
BHAIYA science batao iske peeche ki k agar Kisi bande k face pe pimples ya pimples k marks hain toh usko remove Karne k liye wo banda uski sliva use kar sakta hai agar use kar sakta hai toh Kiya Sach mei uske pimple marks remove honge aur agar remove honge toh q aur kaise honge ?
Yes it can but if u use the saliva after wakingng up because and u don't have to take saliva inside use that saliva bcz over the night when we sleep the saliva remains in our mouth and due to which many toxic substance also gets mixed in our saliva and these toxins are formed only due to the food we eat in dinner I hope it helps u
@techstark99 no I don't wanna use but there is a TH-camr who uploads a that type of video then I was asking this question from sir that TH-camr was not giving answer to me so that !
Sir plz stop using sentences with double meaning.. It makes uncomfortable sometimes Let me share a incident why I hate such statements :- My maths teacher (11th) was good first but after sometimes he started using double meaning sentences and all boys use to cheer him up and then targeted 2-3 girls like once he said " Agar me aapke age ka hota to aap pe try jaroor karta" And we felt this disgusting still we didn't complain about him... But this getting worse day by day.. We even saw him smoking outside class... And at last he said something extreme level uncomfortable statement so we decided to complain about him... We did and he got suspend forever.. That's why it's disturbing so stop using this... Plzz make only educational videos
Sir as a student ek bat khena chata hu i know aapne funny way mai video create Kiya hai lekin aapko niche girane ke liye koi bekham mai controversy na karle is video sai ❤ sir be carefull 😊
Sir mai iss saal 10 me hu aur mujhe pata hai ki mai math mai fail ho jaunga aur 12 me biology lunga aur uske baad d pharm karke chemistry ki dukan kholne me koi dikkat hogi ?mere math me fail hone ke karan 10 me❤❤❤❤😢
Sir sorry to say you but you are a teacher and I am very hurt when I listen this sir agar aap hi desh ke youth ko bigadoge toh sir aapka guru bannd ka kya faeda pls sir don't use these word
Ye main 6th standard tabhi karta thaa caustic soda bolte iss chemical ko main bottle main dal kr upar balloon laga deta thaa hydrogen gas fill krne ke badh usko mstt hawa main rheti balloon ( As hydrogen and helium gas are lighter)

Algebra
* (a + b)² = a² + 2ab + b²
* (a - b)² = a² - 2ab + b²
* (a + b)(a - b) = a² - b²
* (a + b)³ = a³ + 3a²b + 3ab² + b³
* (a - b)³ = a³ - 3a²b + 3ab² - b³
* a³ + b³ = (a + b)(a² - ab + b²)
* a³ - b³ = (a - b)(a² + ab + b²)
Arithmetic Progressions (AP)
* nth term (an): an = a + (n - 1)d
* Sum of n terms (Sn): Sn = n/2 [2a + (n - 1)d]
* Sum of n terms (Sn): Sn = n/2 (a + l)
Geometry
* Area of a triangle: 1/2 × base × height

Thankyou brother I was searching in the comment section for this ❤
If the drain pipe is of plastic..
It melted at 80°C.....so how is it useful?
This reaction we had also study in p block class 11
Aluminium +sodium hydroxide+water react to form a coordination compound (sodium tetrahydroxo aluminate(III)) +H² gas is released which is used to remove blockage from drainage pipes
