The color in KMnO4 arises from an electronic transition, but it is actually not a d-d ... When the light is reflected (or transmitted) it is missing the frequencies of the light absorbed, and so it looks pink.
The heat of combustion for ethane, C 2 H 6 , is 52.0 kJ/g. How much heat could be released if 1 mol of ethane undergoes full combustion? Answer:
A sample of gas occupies 10l under a pressure of 1atm. what will be its volume if the pressure is increased to 2atm ? assuming that temperature of the gas sample does not change

Valence electron of pd Pd has ten valence electrons in the neutral atom. There are no charges and no X-type ligands in the complex; as, this is a d 10 complex.

why nnitroalkanes are highly polor compounds*
calculate the concentration of the Naoh solution you have prepared on the basis of the measured mass of the pellets used in the solution volume
This cycloaddition reaction involves sixteen electrons; hence, it must be suprafacial on one component and antarafacial on the other. Thus, it must be a [14s + 2a] or a [14a + 2s]

Experimental evidence for the existence of the atomic nucleus comes from: (1) Millikan's oil drop experiment (2) Atomic emission spectroscopy (3) The magnetic bending of
Mostly compounds of d block elements exibitcolour dueto d-d transistions between partially filled eg and t2gbut the reason for colour of KmnO4 and K2Cr2O7 is due to partial chanrge transfer between central atom and oxygen which causes colour
