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