Help me to go through this problem. The vapour pressure of a liquid depends on: (a) Temperature but not on volume (b) Volume but not on temperature (c) Temperature and volume (d) Neither on temperature nor on volume
The equilibrium constant can be treated as a particular type of molecular distribution. Consider the simplest gas-phase reaction, one in which molecules of A are converted to molecules of B. the reaction, described by the equation Q : Oxoacids of halogens Why oxidising Why oxidising character of oxoacids of halogens decreases as oxidation number increases?
Why oxidising character of oxoacids of halogens decreases as oxidation number increases?
What is the utilization of glacial acetic acid? Briefly describe the uses.
Basic character of amines is related to their structural arrangement. Basic strength of amines depends on the relative ease of formation of the corresponding cation by accepting a proton from the acid. Greater the stability of cation is, more is basic strength of amine.Alkyl a
