    Newton's fourth law-
    Every book continues to be at rest and covered with dust until and unless internal or external exams appears.
    The speed of page turning is directly proportional to the syllabus to be covered , but tension remains constant😀😀😀

    Amazing, I'm currently 12th appearing students preparing for jee, mai apne kuch chote bhai behno ko kuch batana chahunga jinko padhai me bilkul intrest nahi hai aur wo soch rahe hai ki 10th se padhunga ya 11th se... let me tell you my story, mujhe chemistry se kaafi nafrat tha aur phir kya mai 9th, 10th aur 11th me bilkul v chemistry nahi padha, by the way mujhe study me bilkul v intrest nahi tha and that's why mai padhna jaroori nahi samjha, mujhe technology me kaafi intrest tha aur maine different different programming language (python, bash, sql) and web designing sikha, mujhe padhai likhai sab bakwas lagta tha aur mai sochta tha koi jugad karke 12th kar hi lunga phir college life but dost mujhe bahot late realise hua ki mai galt track pe tha aur mujhe kaafi regret hai is chiz ka ki mai apna 9th,10th and 11th waste kar diya, there is no substitute agar aaj nahi mehnat karoge to kavi na kavi karna hi padega aur jab karna padega tab bahot jayada karna padega aur ush time tumhare pass koi aur option nahi hoga like 9th, 10th me nahi to 11th 12th me aur agar yaha v nahi kia to.... Kuch v nahi keh sakta🙂 Wish you all the best guy's, fod ke rakh do 😊😊😊

    Hope this helps you..🫶

      E.g. C= 12 , H= 1 , O= 16
      C⁶H¹²O⁶= mass of C× no. Of atoms and same goes for everyone
      = 12(6) + 1(12) + 16(6)
      72+12+96= 180u
      I hope uhh will understand

    Trick to learn some ions📍
    When an element have only one atom then the ions will be same as valency of the element (+) eg:hydrogen=+1,Na=+1
    When the element have two atoms then the ions will be same as valency but negative(-) eg:hydride=-1,oxide=-2
    When the element have three atom then ions will be same as valency but negative eg:carbonate-2,sulphate-2
