conquerpro:
does anyone know what i should do about the mass spectra and ir chapter?im really confused when it comes to observing the peak.should i memorize the nature of the peaks of the compounds or what?
NotAbod:
No, do not memorise it. Try to understand it. Practice questions about them and read the examiner reports. They are very easy, you only need to understand them. Also, you can try searching youtube for videos that may help you understand better.
Sorry, I forgot about it, been a year :/
conquerpro:
can anyone please explain how to make an overall redox equation?i know that you need to combine the 2 equations.but what do you do after that?i need the full detailed explanion ASAP.please someone.
Suryaw1:
I can help you all. For electrolysis of aluminum from its oxide, u have to build the equation. Then use chemical calculation method.
For the half redox equation, give me a question. I will solve it and give the explanation.

Hi. Dont worry.
Refresh your memeory: If its an element, the oxidation state is zero.
That helps knowing that oxidation state of P4, S8, O2, O3, Cl2, Br2, N2 as zero!
Good luck in your exams
