This is a common example of a titration calculation which can be broken down into several key steps:1) Write a balanced equation for the redox reaction:MnO4 - + 8H+ + 5Fe2+ --> Mn2+ + 4H2O + 5Fe3+(This...

The enthalpy change of hydrogenation is less exothermic than suggested by the Kekulé model ( -208kJmol^-1 instead of the expected -357kJmol^-1), meaning Benzene is more thermodynamical...

There should be five peaks. In the process of bombarding the Br2 molecule with electrons to charge it, the molecule can fragment into 2 Br atoms. We should therefore expect to see peaks at 79 and 81 m/z. ...

This question is an acid calculation question so it requires you to recall key formulas relating to weak acids. As the Ka of HCOOH has been given, I would start by writing an expression for Ka. Ka= [HCOO-...

Hydrogen bonding occurs in water due to the large electronegativity difference between the hydrogen atoms and the oxygen atom.The oxygen attracts the shared pair of electrons towards itself leaving the hy...
