for refraction of sound (i never did ANY experiment, just read them in buks) in a ripple tank, place a piece of plastic, which shallows the ripple tank n making the medium less dense thus refracting the sound waves.
assume y as x
CxHx+33+24+33=132
12x+x+90=132
x=3.23=3
Cx=12x3=36
36+y+90=132
soy=6
check
HO2CCxHyCO2H
1+16x2+12+12x3+1x6+12+16x2+1=132
Are you sure?
r u sure v have to learn something like that?
I think we only have to learn how it reacts with oxygen to produce energy. Plus advantages and disadvantages of fuel cell.
im using chemistry matters. can u please tell me where exactly is this fuel cell covered in this book? or if u could tell me which book are you using?
Its optional
How it is use to generate electricity, Advantage disadvantage and how it is extracted (Found)
The question is; When v electrolyse copper sulphate with inert electrodes, the copper is deposited at the cathode! Whereas the procedure for electroplatingWhen we electrolyse copper sulphate with copper as the anode and some other metal as the cathode the metal acting as cathode gets copper plated. WHY CAN'T WE JUST PLACE AN INERT ANODE AND THE METAL TO BE PLATED AS THE CATHODE AND DO ELECTROPLATING???? please xplain! :-/
