NANDANI KUMARI • asked a question

Following reactions occur at cathode during the electrolysis of aqueous copper (II) chloride solution:

Cu2+(aq) + 2 e-2 ———–> Cu(s) E = + 0.34 V

H+(aq) + e-1 ————-> 1/2H2(g) E = 0.00 V

On the...

SinceECu2+/CuECu2+/Cuhas a greater positive value thanEH+/HEH+/H, the reaction that is feasible at the cathode is

Cu2+(aq)+2eCu(s)

Voices inside the head


It kills you from inside,

Haunts every night

Echoes inside the head

Like demons calling from hell.

Paint a smile

Of no joy

Keep moving

Thinking you will find what lacks behind.

Say, Hi! To your friends

Give them a smile

Yes, I’m proud of you, boy

Even it kills you from inside.

Your girlfriend left you at the edge

What a fucking disgrace!

Now you even can’t concentrate

Your study going down the drain.

The speed of light does not depend upon the temperature of air but the speed of sound depends on it. Why?

As we know that wave of sound is a mechanical wave and its speed is given by

v = (γRT/M)

whereas the wave of light is an electromagnetic wave and its speed is given by

c = (1/εoμo) 

So speed of sound depends on temperature of air but speed of light doesn't.
