1:05:28 It is exothermic reaction as heat is produced

[Nidhis_shorts]

How to remember reactivity series :

Please : Potassium (K)
Stop :Sodium (Na)
Calling :Calcium (Ca)
Me :Magnesium (Mg)
A :Aluminium (Al)
Zebra :Zinc (Zn)
I :Iron (Fe)
Truly :Tin (Sn)
Like:Lead (Pb)
Her:Hydrogen (H)
Calling:Copper (Cu)
Me :Mercury (Hg)
Super:Silver (Ag)
Power:Platinum(Pt)
Giraffe :Gold (Au)

I hope you will remember reactivity series by this trick...
I hope it was helpful to you.

Reactivity series
K = kasi
Na = Nath
Ca= Ca
Mg= Mali
Al=Aloo
zn= Zara
Fe= Feeke
P= Pakka
H= Hai
Cu= Kon
Hg=Ha
Ag= Aage
Au= Aao
Hope this work 🙂🙂


Edit = thanku for 8 like I never get this much likes 🥲🥲
Edit 2 OMG 52 likes 🙀😱 I can't believe

Pahle mujhe ye chapter itna tough lagta thaa matlab mein soch thee thee ke first chapter hee itna difficult h tho aage kya hoga lekin mene Mansi mam ka iss chapter ka pura session dekha and I was just like iss chapter mein kya thaa itna easy h ye tho matlab Mansi mam kuch bhe krsakti h thanku much mam ❤

1:05:00 it is a exothermic reaction because heat is produced
Thank u mam so much
I am a middle class boy, I wanted to study by paid batches but then I found your channel
U are doing such a great work mam, thank u so much mam
I have also booked your book 😊.

[Awasthiji__]

I pray to God that everyone got more than 95%.

[kanikabhardwaj]

the way mansi mam teaches us❤. she literally treats us like kids and make us understand the topics in the most easiest and efficient manner. i really love watching her lectures. The best teacher for science sst as well as eng.. lotss of love!!

[kusumsaroha]

Mam please please please it's a humble request please bring the latest edition of Maths and science one shot book for the 2024-25 batch as we can start our practice early to score good in boards. Who so ever agree🤔🤔

[sonirajput]

Mam, you are the best Teacher of my life 😊.. becoz itne easy way m ap Maths & Science padha deti ho ..❤... Fir hard nhi lagti .... Or m phle weak thi 8 th class m Maths m, but now, jbse maine apki 9 th class se videos dekhni start ki h ... M bhot achhi ho gyi hu Maths m 🎉..ye sb apki wajah se hua h mam 💝✨😌
Thank you so much Mam 💗🥰🥰

[yasaswinikavyapriya]

Ma'am aap itna ache se kaise pada rahe ho.... literally....i follow all ur videos....each and every subject ka...aadu is very lucky ma'am to have such a wonderful teacher as mother....❤

[Anny_.]

really mam, you are a very good teacher, and you are becoming my favorite teacher I am in 10th now and I hope mai apse padh kr bohot ache percentage banau and thank you so much mam chemistry apse padh kr samjh aa rhi hei bohot ❤😊😊✨🍁🌺🌺

Kasam se bata rahe hai ye chapter pehle muje itna tough lag raha tha jab se mansi ma'am ki introduction video dekha mere liye ab ye kuch nahi hai mam ap ne pura dimak hi khol diya

[tanyajain]

Mam your way of teaching is best
For Maths chemistry physics biology all my friends go to coaching but I study at home
Your explanation is very easy
Thankyou so much mam for such videos
East or west mansi mam is best🎉
Like ❤️ who love the way of teaching of Mansi mam👩🏻‍🏫

[aarohi]

I feel blessed that i discoverd you from 7th standard. Without you mam i wouldn't have survived maths and it's majestic that how simply u makes me understand a complex topic.Thank u so much mam 💗

[bhai]

I am confused in eq OH or H2O how to balance it. But u cleared my confusion 😊 thank u so much mam

[a-soldtonew]

Mam from 7th I am being with you and now I am in 10th not willing to leave your teachings I hope you also teach in 11th
