How one know that which MnO-4 half equation use
MnO4– + 4H++ 3e– MnO2 + 2H2O +1.67
MnO4– + 8H++ 5e– Mn2+ + 4H2O +1.52
MnO4– + 4H++ 3e– MnO2 + 2H2O +1.67
MnO4– + 8H++ 5e– Mn2+ + 4H2O +1.52

It just simply does not react with bromine 'No reaction occurs'.View attachment 64308View attachment 64309
Can anybody help . Nov/17/p42 question 3.
Why has the NH not reacted ?
View attachment 64310
As seen on the marking scheme
why does br2 not react with the double bond?It just simply does not react with bromine 'No reaction occurs'.
Here the question is basically focusing on where the the bromine will attach what will be the specified position which in this case are 2 & 6 as -OH is electron donating group.
Thank you so much!!View attachment 64313
CCl4 is used as a solvent for electrophillic addition to occur with bromine But as seen in the question the bromine is in aqueous form thus it will not react with the double bond.
You are welcomeThank you so much!!
For your first question,Hey can some one help with the concept of tetrahedral and square planer complex? How to differentiate between the two?
Also this question, how do we know which equation from databooklet to use for Fe3 : 1) Fe3 + 3e- => Fe or 2) Fe3 + e- => Fe2
Thankyou so much Hamnah
x moles of HI have dissociated which will give x/2 moles of H2 and x/2 moles of I2Hydrogen Iodide dissociates into H2 and I2.
2HI (g) <-----> H2 (g) + I2 (g) (the reaction goes in both directions)
In an experiment, b mol of hydrogen iodide were put into a sealed vessel at pressure p. At equilibrium, x mol of the hydrogen iodide had dissociated. Which expression for Kp is correct?
A. x^2/(b-x)^2 B. x^2×p^2/(b-x)^2 C. x^2×p^2/4b(b-x) D. x^2/4(b-x)^2
The ice table method doesnt work here. The answer is D.
I am getting x^2/(b-2x)^2
Is it B?View attachment 64351 Can anyone solve this, please?
