Small Binomial Doubt
how did it break
how did (21x20 + 8 )^2024 break in 21m + 8^2024
Ques was finding remainder when 448^2024 was divided by 21...
Complex numbers
This solution makes sense to me, but here's what I did:
argument of (1 + z) / (1 + z_conj) = arg(1+z) - arg(1+z_conj) = arg(1) * arg(z) - arg(1) * arg(z_conj) = 0 since arg(1) = 0
I got 0 using the log-like properties of argument, why am I wrong?...
Coordinate compounds CFT
why does crystal field split even in case of like Sc3+,if there is no electron in the d orbital then there is no repulsion between ligand and metal in d orbital hence it should not split
AND
Since CFT is based on electrostatic interactions then how can it have shapes like octahedral or tetrahedral if I remember correctly ionic bonds donโt have shapes...

Question 11
I am pretty sure my approach is correct but from my method ans comes when I take given heat of combustion and heat of formation of c2h2, CO2 and h2o with signs opposite of given. Can I do that??...
Element name in Periodic Table
Should I learn official name of elements in Periodic table with atomic number 100+
(like Mendelevium)
Or
Just IUPAC naming (like unnilunium)

How much solid Na2S2O3 should be added to 1.0 L of water so that 0.0005 mol Cd (OH2) could just barely dissolve?K1 and K2 for S2O3-- complexation with Cd++ are 8.3 ร 10^3 and 2.5 ร 10^2, respectively. Ksp (Cd(OH)2 = 4.5 ร 10โ15
ques in case photo is not clear...
