its her

Oh..okay!

 

[ZaqZainab]

Explanation ???

 

[shazmina]

Iridescent yes ur rite..platinum ofcourse does conducts electricity....evn nabeel brws suggestion is rite....newys lets wait n c his explanation..lol

Yes, that's what we've studied in the past three years!
Btw, it's 'her' not 'his'.

yep ur rite..buhahahahahaha rele....m sry.....
i srsly hv dis confusion ovr here...lol

Haha, yeah you do have the confusion

Hi
Could someone pls tell me the best books for Bio, Physics and Chemistry?
I have about an year for preparing so should I learn from two books or just one?
Thanx

waiting over here is the explaination
PLATINIUM MOSTLY CONTAINS''D'' SUBSHELL RESULTING IN LESS SHEILDING EFFECT , AS A RESULT OF LOWER SHEILDING EFFECT THE NUCLEUS HAVE STRONG ATTRACTIVE FORCES TOWARDS ITS ALL ELECTRONS AND SO THE EECTRONS ARE UNALBLE TO FLOW OR BE ATTRACTED BY ANY OTHER ATOM.
YES THEY DO R USED IN ELECTROLYSIS BUT AS INERT ELECTRODES WHICH DONOT DONATE ELECTRONS BUT ACTUALLY ACCEPT THEM
so here is the explaination , any questions so I ll ask my professor

Electrodes let electricity pass through them. If Platinum doesn't, how can electrolysis even take place. How will the electricity reach the electrolyte?

I just want to understand the concept.
By logic, either of the properties of Platinum should be correct, the non-conducting or the electrolytic.

Yes, you are absolutely correct.

brother i mentioned dat platinium acts as an inert electrode which attracts the electrons , it in no way allows electricity to pass through them , thx phenomina which u r saying would happen in the case when electrode allows its electrons to move but platinium doesnot allow thx and so is used as inert electrode

 

[Nabeel.Ahmad]

So your teacher has made a new discovery that disproves all previously known scientific facts and the numerous articles in books and the internet.

If the current doesn't pass, that means electrolysis hasn't taken place at all.

guyz I m nt really a scientist and wtever she said meant something which I m unable to make u people understand , if schools were going on so I must had brought 4 u people a complete explaination on thx point , I ll try my level best to get u guyz its full electrolysis ,platinium explaination

Thanks for your efforts.

Which reaction is more exothermic: Magnesium+Sulfur or Potassium+Fluorine ? The book says it's Potassium+Fluorine but can someone please explain why ? Thanks in advance

Both the reactions are exothermic. The reaction which is more rapid and violent is the one which releases more energy. Potassium is more reactive than Magnesium and Flourine is more reactive than Sulfur. Thus, Potassium and Flourine will react more readily than Magnesium and Sulfur. Therefore, the reaction between Potassium and Flourine is more exothermic.
