Thank you for your help.

Today I learned that it is very difficult to think about an innovative idea, but its very astonishing when the idea strikes our mind automatically.

Due to the potential difference by any active element in the circuit.

Electrons drift due to their collision with atoms of a conductor.

Homework Statement :[/B] When a steady current flows through a conductor, the electrons in it move with a certain average 'drift speed'. The drift speed of electrons for a typical copper wire is about 1 mm s-1 . How is it then that an electric bulb lights up as soon as we turn the switch on...

Thank You! Your advice helped me a lot...

I searched for the correct formula on few of my textbooks, and I saw one example of Basic Copper Carbonate as CuSO4.Cu(OH)2 . And on certain sites too, their was anhydrous form of Basic Carbonates. Can you tell me the correct one?

1. 2Mg+O2 -----> 2MgO 2. MgO + H2O----------> Mg(OH)2 Now, the third reaction is going to be : 3. Mg(OH)2 + CO2 -----------> MgCO3.Mg(OH)2 Please check if the third reaction is correct or not.

So we arrive at at the conclusion that the layer on the surface of Magnesium (corroded) is due to the Basic Magnesium Carbonate formed. But, what could be the reactions during the corrosion process? Please help me in this case.

The color of basic Mg Carbonate is pinkish-grey... as far as my knowledge is concerned.

White though?? You mean a white layer must have been deposited??

Then it must be Basic Carbonate of Mg only...

Not pitted, but just its surface had been defaced to some extent. Something greyish has been deposited on its surface...

1. In my Homework, the teacher gave me the project to collect the sample of corroded magnesium (pure metal, and not an alloy) and write a detailed description about the process related to it. 2. Although I collected the corroded sample, yet I am unable to write its description. What I know...

The Big Bang Theory is right now the most acceptable theory for the creation of Universe... But, as per the Law of Conservation of Matter, matter can neither be CREATED, nor be destroyed... So, shall we conclude by saying that Universe existed earlier also and would tend to exist forever?
