thank you! concise and conceptual explanation
MashaAllah...❤
Sir very well explained the paper...
Solute u sir....!
Bestest explanation ❤️
Thanks for giving us information 😊😊
Thanks your are the best teacher
Well explained sir ❤️
well explained...
Thanks sir
Well explanation 👏
Thankyou sir
Great video Sir,learned a lot from you
Thank you so much ❤
Welcome dear. All the best ahead
Q no 32 both are correct a c
Mcq 16 m London dispersion forces NI Hona chaye qk yehi to deciding factor hoty Hain boiling point Ka?
Yes it is londen dispersion forces
Sir concentration can also be a good parameter for rate of reaction bcz aio mcqs ma incorrect statement batani thi tou wahan hum ye kehte hain ka concentration pa depend karta hai aur aik mcqs ma Keh raha hain ka temperature hai how is it possible
A 2M reactant at 25°C Will react differently at 15°C. Though the conc is same
@@ChemistrybyAdil similarly if we keep the temperature constant and change concentration of reactants even then the rate of rxn changes
Yes. But rate constant remains the same if temperature not changed
Sir 31 saturated cnfm hy na?
Yes
Sir 35 ma 4.184 joule ha plzz check this
Assalam o alakium
Sir question no 13 ma volume ata Hy bcz it remains constant in all laws while we are changing other parameters
No dear. V P etc related to moles too
@@ChemistrybyAdil but we are dealing with laws here that's why
@@farazbadshah1484 I also agree with you, bcuz Avogadro's law Mai to no. of moles constant nhi rehtay,
@@waseemahmad3423 yes
It's accurate Ans is volume
@@farazbadshah1484 Meray khyal say to ye MCQ hi thk nhi hai, NUMS walon ko is k grace marks denay chahiye!
Koi bata sakta hai physics mai jo mcq aya ta
Absolute potential energy or gravitational potential energy? Which one is correct
And Magnetic field direct relation with r or inverse? Bht log direct keh rahe
Absolute p.e
B is inverse related to r
@@SohailKhan-mr8jd
Confirm?
But bro majority log Gravitational aur direct relation with r ka keh rahe
Then lets wait for official Nums key
@@invictusgaming5267 nahi yar book mai hai na absolute potential energy ka definition ...absolute is correct..
& inversely proportional to r ,it's according to Amper's circuital law B=u°/2Π × i/r
B is directly related to r, ye kafi tricky MCQ tha, or yahi iska correct answer hai
Asalamoalikum sir g plz is test ko PDF form plz provide kiya kurey it will be more helpful and secondly sir g mere Chem mein 1 year 74 and second year mein 77 hain to Kya mein issko improve kuro ??
.....................Thanks
Wasalam. Yes if you think that you can improve than go for it.
Alright sir g thanks a ton or Kya aghr mein first year ki koi subject improve kuronge to Kya second year ki be wahe subject improve kurna must hain
Don't exactly but ask from board concerned
Alhamdulillah 2 wrong
Sir solubility should decrease down the group solubility directly related hoti hai hydration energy and inversely related hoti hai lattice energy say pr donon he down the group decrease krti hai but in case of alkali metals lattice energy dominate krti hai means lattice energy main decrease ziada hota hai I think mainly bcz size sab say largr hota hai unka apnay period main as compared to hydration energy so hm kahtay solubility increase krti hai but agr alkaline earth metals main aisa nahi hai hydration energy dominate krti hai.
This is my point of view which I crosschecked from byjus website
But agr koi or point hai jiski wajah say increase kr rahi hai to plz explain kr dain .
I cannot share screenshot on TH-cam but copy paste kr sakti hun here is the text from website .
Why Solubility of Alkaline Earth Metals decreases down the Group?
Beryllium ion is the most soluble and the solubility decreases with increasing size so that Barium ion is the least water-soluble alkaline earth metal ion. Solubility in water is related to the ionic nature and size.
Smaller ions have higher charge density and can be solvated by more water molecules. This releases a higher enthalpy of hydration and makes the hydrated ions more stable.
Example: Solubility of Be2+ > Solubility of Mg2+ > Solubility of Ca2+ > Solubility of Sr2+ > Solubility of Ba2+
I have stated that solubility of alkaline earth metal compounds should be asked.
Hydroxides increases
Sulphates decreases
Carbonates insoluble
So the question is ambiguous
Oxide of alkaline earth metal and Hydroxide of alkanine earth metal also increase down the group
Sir nums 2023 upload kren plzz
Yes, sure. Waiting for authentic paper
27 mei 2d ki bhi max value hai?
Yes but it doesn't exist
@@ChemistrybyAdil although it doesn't exist but still according to the question we are supposed to do according to n+l rule..?
But jb hm nucleus sy away jatat tou higher orbitals ki enenergy high hoti to 4s higher orbital hai iss liye 4s best option hai
sir i want this pdf plz send me
drive.google.com/file/d/1zdf9GFHhv2zcHTvItNFWaHY_6rIoEKc3/view?usp=drivesdk
Sir concentration first important factor hai rate of reaction ka i think
Temperature affects first.
@@ChemistrybyAdil Sir but law of mass action!!
Mainy bhi Concentration ko select Kia q k formula main RoR=K(molar concentration) hai
