Magnesium is a group II metal, and therefore has two electrons in it's highest energy ...

A buffer is a solution which resists changes in pH when alkaline or acidic solution is added to it.

Buffers are created based on the equilibrium of a proton donor/ acceptor...

Firstly, we must consider the thermodynamics involved

It is known that a reaction is spontaneous due to thermodynamic favourability if the Gibbs Free Energy is negative. This is further b...

There are several different answers one could make and an exam question would just require one for each. 

1) Propanal - from the ending "al" this is an aldehyde.
