Ammonia is a base and concentrations of ammonia is important for pH calculations. Here pH is determined by calculation of [OH-] by making rice table and using Kb value.
Kb = [OH-][NH4+]/[NH3]
[OH ..read more

Definitely it is not a buffer solution as you are dealing with strong acid and strong base .
But C is not the Handerson equation
It is based on pH + pOH = 14 equation written in a different format.
Write reaction first and as you are mixing volume of ..read more

The formula is wrong its D-Ribose. D-Allose has one CHOH group more.
The L- form in Fischer has all OH- groups on the left side.

To check which combinations of reactions will give ∆G negative that will be the spontaneous reaction.
QuoteIs it okay if the first equation has negative entropy? shouldn't one of them be favourable and the other one non favourable?
Only ∆S w ..read more
