Today is 13/2/2024 and we’ll be having our boards after few days. I am writing this as a memory of my class 10 journey. If you are from 2024 batch, remember to enjoy your 10th to the fullest.

Anyone is here 2025 batch student who not score good in 9 😢but in 10 want to score 95+ 😊😊😊 and try to improve ourselves a lot you can do it 😊😊 hardwork+ smart work= success 🎉🎉🎉🎉😊😊
ONE ADVICE TO MY JUNIORS ....AS I'M NOW IN CLASS 11th ...and Believe me this man is awesome....follow him that's all ...in shot you can call him your true GURU ....His teaching and your way of studying is the key to success.....❤ I LEARNT MANY THINGS FROM MR.PRASHANT KIRAD SIR AND LOT'S OF LOVE TO YOU ALL .... MAY YOU ACHIEVE 90+ IN YOUR 10TH BOARDS (2024-25) AND GOD BLESS YOU ALL ❤🙏🕉️......ONE LAST ADVICE IS FOLLOW HIM TILL THE END AND THEN YOU'LL GET YOUR RESULT THAT WILL FULFILL YOU ....OK THAT'S ALL THANKS ❤
4:16 Burning of candle is both physical and chemical change. Since when the candle burns the wax melts which is a physical change and while burning the oxygen required for burning changes to carbon dioxide which is a chemical change.
ANSWER 9:42 Unbalanced 13:30 calcium carbonate 56:40 2 NaOH + Al2O3 ---> 2NaAlO2 + H20 58:38 = Hydrogen is getting oxidation 58:48 = it is going throw a combination Reaction 59:04 no it is not performing a redox reaction 1:01:03 = 6HCL + Al2O3 -----> 2AlCl3 + 3H2O 1:01:09= C3H8 + 5 O2 ---> 3CO2 + 4H2O 1:06:30 IT IS A TYPE OF DOUBLE Displacement Reaction

All of u don't lose hope We have the time to restart👍🏻 If u done nothing till now So after starting now we can score 90℅ above Mark's Just try and focus on ur studies✏ Best of luck🤞to all my friends❤
To my juniors first of all congratulations for passing class 9th. One thing which I noticed a lot is Bahut log honge Jo tumhe daraenge ki boards hai boards hai tbh it’s just like your normal exam but difference is that ki aup dusre school me jaoge aur paper tohra diff hoga Maine kharide reference books Kafi sara but padha ek bhi nai only focused on ncert Jo do pre boards huye that helped me a lot and I managed to score 81% which is enough for me but yeah ik if I had studied more I could have get more just don’t stress yourself much and all the besttttt❤️remember to focus on your pre boards
59:13 In this reaction, hydrogen (H₂) is oxidized to form water (H₂O), while oxygen (O₂) is reduced. So, both oxidation and reduction processes occur simultaneously, making it a redox reaction.

ANSWER
9:42 Unbalanced
13:30 calcium carbonate
56:40 2 NaOH + Al2O3 ---> 2NaAlO2 + H20
58:38 = Hydrogen is getting oxidation
58:48 = it is going throw a combination Reaction
59:04 no it is not performing a redox reaction
1:01:03 = 6HCL + Al2O3 -----> 2AlCl3 + 3H2O
1:01:09= C3H8 + 5 O2 ---> 3CO2 + 4H2O
1:06:30 IT IS A TYPE OF DOUBLE Displacement Reaction
Hydrogen is added and also oxygen is added so we can say redox reaction is occured
And we can also write it as 4NaOH + 2Al2O3 =4NaAlO2 +2H2O
bro The answer is 5CL + AL2O3 ------> 2ALCL3 + 3H2O plz correct it

lead nitrate on heating turns into lead oxide + nitrogen dioxide + oxygen
2Pb(NO3)2 ______ 2PbO + 4NO2 + 02
You should use this ------> instead of ______ 😀👍
Waah topper 🔥🔥

To my juniors first of all congratulations for passing class 9th. One thing which I noticed a lot is Bahut log honge Jo tumhe daraenge ki boards hai boards hai tbh it’s just like your normal exam but difference is that ki aup dusre school me jaoge aur paper tohra diff hoga Maine kharide reference books Kafi sara but padha ek bhi nai only focused on ncert Jo do pre boards huye that helped me a lot and I managed to score 81% which is enough for me but yeah ik if I had studied more I could have get more just don’t stress yourself much and all the besttttt❤️remember to focus on your pre boards
Thank you yahi ho raha hai abhi to ki 10 th h ab pta chalega 😢

59:13 In this reaction, hydrogen (H₂) is oxidized to form water (H₂O), while oxygen (O₂) is reduced. So, both oxidation and reduction processes occur simultaneously, making it a redox reaction.
Correct
In every reaction there is always an element that is oxidised and at the same time another element is reduced.
Thanks for kind information
Bro can you give me the exphub pyq and question practice booklet....it will be very helpful
I don't have ask for someone else
56:48 hw question
4NaOH + 2Al2O3 -------> 4NaAlO2 + 2H2O
Correct
Na Bhai
2NaOH + Al2 O3 → 2NaAlO2 + H2O.
Is actually correct 😁

Outstanding video sir 🎉
Heads off to you ❤
I wish and pray to God that everyone gets 99.9% in their board examination in each and every subject and everyone reach their goals .
Thanks 🙏👍
56:49 answer hai
4(NaOH) + 2(Al2O3) - 4(NaAlO2) + 2(H2O)
Bhai 4 ki jagah 2 bhi chalega
@aryashkowe167 phir O equal nhi hoga
2(NaOH)+Al2O3----> 2(NaAlO2)+H20 it will be correct...
2NaOH+Al2O3-->2NaAlO2+H2O
Ye bhi chalega bhai
