It all started when I bet with my senior brother, that my warm tea will freeze before his, but instead his cold tea froze first....I felt bad so I tried it on my own with warm and cold water yet still the cold water freezes late. I was wondering why warm water freezes faster than cold water.....because with what I knw, cold water is likely to drop in temperature than hot or warm water. Please can any chemist open my eyes on this?
Thanks.

As simple as it is.....distinguish them through the center of each specimen or break to identify

yes you can

i cant challenge him........ he is more than i am...but thanks anyway.
Your topic, "Problem with Schrodinger equation" made me think that you challenged Schrodinger as being incorrect, instead of your having a "Question about the Schrodinger equation."
I can derive the equation, i know its main features for the electron in an atom. but i dnt know the physical meaning of the wave function of an atom and i cnt distinguish between the angular and radial probability function.....please help
pls can you help?°

we dnt do home work here...but if i will help, try to rearrange the values and write the equation..it works with the KOH mass

Ran, you just hit it....thats a perfect example

you have the space but........chemistry lab is a long shot with such sum.....

the most remarkable of Bohrs theory was in explaining the spectrum of Hydrogen and hydrogen-like atoms, it could not explain the spectrum of many electrons

it really depends on the system

yes enthalpy is right

becaus the earth ha
s its own potential energy due to rotation, then its temperature will therefore be increased at increased pressure.....simple

Its about the reaction between Pottasium permanganet (KMnO4) with concentrated sulphuric acid (H2SO4) and ethanol (CH3CH2OH)
2KMnO4 + H2SO4 = Mn2O7 + H2O + K2SO4
Its quite nice in a small scale though!!
