الســـلام عليكم ورحمة الله وبركاته ..

عند زيارتي لأحد المواقع الأجنبية ...

وجدت بعض الأغاني والتي تخص مواضيع الكيمياء ..

و الأغاني رائعة جداً ..

لأنها تتحدث عن موضوع معين ...

فمثلاً في الخلية الكيميائية .... تتحدث عن كل شيء يحدث في الخلية

سواءً عملية الأكسدة والإختزال ... وكيفية الفقد والإكتساب ..إلخ ..

ولذلك أقتفطت لكم بعض الأغــاني الكيميائية من المواقع الأجنبية ..

وفي الحقيقة ترجمت بعضها ولكن .... وجدت إنها لو وضعت باللغة

الإنجليزية أفضل بكثير .;).


وأتمنى أن تنال إعجــابكم ....


إذن ....

منقالبأنالكيمياءمعقدةوملوثة...

الخلية الكيميائية ..

أعتقد إنها رائــــــــعة ... جداااً ...

CHEMICAL CELL

Electrochemistry - Based on "Bat Out of Hell"
Original Words and Music by Jim Steinman

The metal’s dissolving and the ions are forming way down at the anode today,
The solution’s 1 molar, it’s 1 atmosphere pressure and the temperature’s 298K,
There’s aqueous ions of the strip of the metal that’s acting as an electrode,
Oh and by the voltmeter (of infinite resistance) there's a filter-paper salt bridge, joining the circuit -
It was letting charged particles flow;

Oh oxidation happens as electron loss as atoms ionise,
And reduction’s the process of electron gain (the opposite of oxidise)
And they happen together in a metal half-cell, each reaction is reversible;
But one reaction happens slightly more than the other - there’s imbalance of charge,
Electrode potential…

In a chemical cell there’s a movement of electrons,
From the negative half-cell through the conducting wire they’re gone, gone, gone;
In a chemical cell there’s a movement of electrons,
And when the cell potential is positive the reaction’s feasible-le-le-le -
But with a high energy of activation, not kinetically possible.

Electrons leave the anode and they flow round the cell (in cell statements, from the left to the right)
And the ions are formed - they’re transferred by the salt bridge ‘cos it’s soaked in an electrolyte;
Positive ions undergo reductions at the cathode, with electron gain,
And (aq) turns to (s) as metal atoms form - and charge is separated again.

And the redox potential of each half-cell’s worked out
With the hydrogen standard half-cell,
It’s made of platinum black adsorbing hydrogen gas,
And H+ ions come from HCl.
And its potential is zero V at 298K, standard hydrogen half cell,
And its potential is zero V at 298K, potential is zero V at 298K, potential is zero V at 298K,
Standard hydrogen, standard hydrogen, standard hydrogen half-cell!

In a chemical cell, there’s a movement of electrons,
From the negative half-cell through the conducting wire they’re gone, gone, gone,
In a chemical cell there’s a movement of electrons,
And when the cell potential is positive, the reaction’s feasible-le-le-le
But with a high energy of activation, not kinetically possible -
But with high energy of activation, not kinetically possible…


And the reaction goes, cos it’s feasible,
If the standard cell potential’s positive:
The E 0 cell values for each half cell add -
The voltage of the negative half-cell has to have its sign changed
'Cos its half-equation’s reversed,
'Cos it has to be an oxidation - not electron gain…
'Cos it has to be an oxidation - not electron gain

And the more negative the electrode potential is,
The more reactive is the metal that’s oxidised,
And the more its strength as a reducing agent as well,
The more likely it is to lose its electrons
They’re being lost by the metal that's at the anode
In a chemical cell,
And the more positive the electrode potential is,
The less reactive is the metal (won’t be oxidised),
And the more its strength as an oxidant as well,
The less likely it is to lose its electrons, electrons,
They’re being gained by the ions next to the cathode
In a chemical cell!
They’re in a chemical cell!
They’re in a chemical cell!
They’re in a chemical ceeeeeeeeeeeeeellllll!!!

MAGNESIUM THE BEAUTIFUL
(to the tune of "America the Beautiful")

For alkyl halides' majesty
Magnesium is meant,
Assisted by completely dry
E-ther-e-al sol-vent.
Magnesium, Magnesium,
A Grignard has M-g,
It's understood, its bonds are good
From C to shining C.

A carbonyl is polarized,
Its carbon end is plus.
A nucleophile will thus attack
The carbon nucleus.
Magnesium, Magnesium,
A Grignard has M-g,
Each one is fond of making bonds
From C to shining C.

Oh, Grignards can make alcohols,
Of types there are but three.
When Grignards add formaldehyde
The product's primary.
Magnesium, Magnesium,
A Grignard has M-g,
Its alkyl group gives out a whoop
As C grabs shining C.

For alcohols, a Grignard and
A carbonyl collide.
A secondary's synthesis
Requires an aldehyde.
Magnesium, Magnesium,
A Grignard has M-g,
And makes a bond to correspond
From C to shining C.

For tertiary alcohols
An ester captures two,
But if you send a ketone, then
Just one Grignard will do.
Magnesium, Magnesium,
A Grignard has M-g,
We don't need zinc to make a link
From C to shining C.

Now if you need an acid of
The carboxylic kind,
Just bubble past a simple gas:
To Grignards it will bind.
Magnesium, Magnesium,
A Grignard has M-g,
It sticks like glue to CO2,
Joins C to lonely C.

One Grignard grabs a nitrile, then
The next leaves it alone.
The product, during workup, hy-
Drolyzes to ketone.
Magnesium, Magnesium,
Is held in high regard
By chemists, who give honor to
Monsieur Victor Grignard.

... عن الكيتون ...

Oh, my ketone!


(to the tune of "Oh, My Darling Clementine")

Oh, my ketone! Oh, my ketone!
And my primary amine.
You reacted, lost some water and
You formed a new imine.

Now the lone pair on the N then
Bonds with carbonyl C.
Pi electrons go to O, a
Proton shifts fast as can be.

Now the O is feeling greedy
Grabs an H from OH3.
Free electrons from the N then
Form a pi bond, water leaves.

Now the N is protonated
And a plus charge can be seen.
So the water yanks the H off
And we've formed a new imine.

Oh, my ketone! Oh, my ketone!
And my primary amine.
You reacted, lost some water and
You formed a new imine.

I’M STILL BONDING

The Ballad of Magnesium Chloride - based on "I’m Still Standing"
Original Words & Music by Bernie Taupin and Elton John

MAGNESIUM (to the audience)
You can never trust halogens -
They pull electrons off time and again,
And what you lose, they gain in negativity,
So you’re stuck to their opposing charge electrostatically.

CHLORINE (to Magnesium)
Quit the whingeing, let me be reduced -
Us oxidants have got a job to do:
I need one more electron for my outer shell -
If you’re reducing me, you’re bound to end up oxidised yourself.

ONE OF THE CHLORIDE IONS (having run off with Magnesium’s electrons)
Don’t you know I’m still bonding - your electrons I’ve acquired -
Looking well and truly minus, feeling like a right halide,
Oh I’m still bonding - I’ve been reduced to
Nicking the electrons off the metals in Groups I and II,
I’m still bonding - yeah yeah yeah!
I’m still bonding - yeah yeah yeah!

MAGNESIUM ION (to the Chloride Ions)
So I’m oxidised and you’re reduced:
I gave my outer shell electrons up to you;
But I’m not big, and I’m charged quite highly -
So your electron cloud’s distorted, and now it’s pulled to me.

Don’t you know I’m still bonding - I had electrons to give -
Looking like a true cation, feeling really positive;
Oh I’m still bonding now that I’ve been through
Losing my electrons to the oxidising likes of you,
I’m still bonding - yeah yeah yeah!
I’m still bonding - yeah yeah yeah!

(instrumental bit during which the other chloride ion joins in and they all link arms and dance about a bit)

ALL TOGETHER (now doing a sort of ionically-bonded can-can)
Don’t you know we’re still bonding - if a bit covalently -
Looking not quite heteropolar, joined electrovalently;
Oh we’re still bonding exothermically,
Forming an ionic solid of high lattice enthalpy,
We’re still bonding - yeah yeah yeah!
We’re still bonding - yeah yeah yeah!

Bonding

Carbon:
With orbitals of sp3
I want to make a bond with thee,
Together we, covalently,
Will translate through eternity!
Hydrogens:
Oh, carbon atom, we respond
With our s orbitals, to bond!



نتمنى لكِ السعــادة ياهالوجينات ...

مقطع لطيف وظريف ...

We Wish You a Happy Halogen

We wish you a happy halogen
We wish you a happy halogen
We wish you a happy halogen
To react with a metal.

Good acid we bring
to you and your base.
We wish you a merry molecule
and a happy halogen.



أنبوبة الإختبــار ..

Test Tubes Bubbling


(to the tune of "Chestnuts Roasting On An Open Fire")

Test tubes bubbling in a water bath
Strong smells nipping at ypur nose.
Tiny molecules with their atoms all aglow
Will find it hard to be inert tonight.

They know that Chlorine's on its way
He's loaded lots of little electrons on his sleigh
And every student's slide rule is on the sly
To see if the teacher really can multiply.

And so I offer you this simple phrase
To chemistry students in this room
Although it's been said many times, many ways
Merry molecules to you.







تحيـــاتي ..

وهناك المزيد من الأغــاني ..
