 (i)  Magnesium oxide is an ionic compound meaning the elements reside in a lattice held together by very strong electrostatic forces of attraction between their oppositely charged ions. Since bonds are b...

First work out the moles of Iron (III) Chloride using the equation concentration = moles/volume, rearranging the eqaution in order to calculate moles gives moles = concentration x volume. Check the units!...

The n+1 rule is used to describe the relationship between peak splitting and the number of protons a particular proton is coupled to - that is, how many protons are attached to the carbons next to the car...

A catalyst lowers the activation energy of a reaction. It does this by providing an alternative, lower energy pathway for the reaction. An example of this - a catalyst may form a complex with the reactant...

Electronegativity is the measure of the tendacy/ability of an atom to withdraw electron density in a chemical bonding pair of elcectrons. It is most commonly measured using the pauling scale.
