Sir I have a doubt and I am really struggling with it right now as I am covering up my basic chemistry topics to rock and roll my basic is only I need to backup Doubt is: if formula of carbonate is CO3² ( the valency is -2) and hydrogen is H+ then how can we prove hydrogen carbonate is HCO3 in your given chart by Criss cross method , ( the valency of co3 is -2 and hydrogen +1 so if we do Criss cross method it should be H2CO3 . Waiting eagerly for your reply sir.
video ke last m jo bhaiya ne kaha hai wo ekdmm sahi kaha hai dont take risk its tenth..**begginer hu abhi se krunga mehnat**DONT LOVE DONT CrY JUST LOVE YOUR PADHAI
This was the video which i needed in class 7th-8th. Especially if you are an ICSE board student and dont want to learn chemical formulas in early classes (7th/8th) even though the teachers tell you to learn them. This is the best video. At the same time, refer to the First Chapter in Viraf Dalals ICSE Chemistry Book for class 9th. You will find a valency table, just by heart it and watch this video 2 times and you are free to go and form almost all the simple compound formulas
One thing really crucial to say , I searched for millions of videos for chemistry as it's my weakest point , couldn't understand anywhere. I was confused watching so many concepts but your speed , teaching skills and mentorship is brilliant .... Thank you sir
⭐️ 4:44 For those who are confused on where to find the table, they are available in your Class 9 Science Textbook: Page no. 37 (Table 3.6 of Science NCERT) Edit: Thanks for the likes. ❤ Edit: 😮
Thank You So Much Sir. I had trouble with the chemical formulas, it was because I hadnt memorized this table but after watching this video all of the chemistry balancing equations became very easy
Such a brilliant teacher Prasant Vaiya🥰👨🏫 I randomly found your video and It's really helpful for me....I am a student from Bangladesh. Thank you for give us this type of precious video with zero cost.😊❤
I have followed you for almost a year now. I used to fear chemistry when I was in 8th. But now that I am in 9th, mere grades mey bahut drastic change hua hai. Mai 45% se seedha 94% per aa gayi hoon all thanks to your explanation! Please keep making videos like this!❤
Bhai CORRECTION : Na+ toh cation h toh vo toh lena Chahta h electrons , Cl- toh anion h vo dena chahta h . At 3:06 mins you told sodium has excess electrons while in reality it has deficiency of one electron
Unhone sahi hi kaha Hai kyunki sodium ke pass ek extra electron hai jise wo kisi aur element ko de kar khud balance ho jayega aur ek electron Dene se hi use last shell me aath electrons aa jayenge
Thanks bhaiyaa ...🙏 This is the most hardest problem which we phase during solve an chemical equation or word equation your every video motivate us... 😊
Just amazing ! Nothing to say sir ! Just awesome! Nobody except you made me understand those problems...thank you so much sir 💕though I am in class 8 but all these were as easy as water ! Thank u very much ✨
OMG .. this video was much needed becuz tomarrow is my science pt 1 exam.. and I was very tense about how can I solve these types of questions but then I see this video in my recommendation then I become very happy.... Thank you bhaiya ❤.. keep going
Sir you are an amazing teacher. You teaches us with all your strength and your energy during the whole class is amazing..... I hope everyone will gain more than 95% in their boards if they listen to you carefully and follow your footsteps 😃👍
I am in 7th grade and still watching this video because I am in ICSE board and tomorrow is my chemistry exam. This is the main chapter coming tomorrow. Thank you so much Bhaiya for this video 😊
