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-...
When attempting to answer a question about complexes, you need to think about three things: the identity of the metal (and its oxidation number), type of ligand (i.e. if...
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...
You can't directly measure lattice enthalpy of a solid crystal, so you have to look at a different method. Usually this would be experimentally or using Hess's Law to construct a Born-Haber cycle. The Bor...
