Firstly all of benzene's bonds are the same length and therefore there cannot be both double bonds and single bonds in the molecule. Secondly the bond angles are all the same as well which would not be th...

We start with aluminium (Al). Al conducts electricity in both solid and molten states, this is because Al has metallic bonding between fixed positive Al^(3+) ions and delocalised electrons. The delocalise...

‘Ionisation energy’ is the term used to describe the amount of energy it takes to remove an electron from an atom to form a positively charged ion. It is usually represented by the unit kJ/mol, meaning it...

The number of moles is related to the amount of a substance we have. If we were to use the number of particles, the numbers would be huge and impractical to use. So, Avagadro's number provides us a link w...

There are 5 main factors that affect the rate of reaction. 1. Concentration: Increasing the concentration increases the frequency of collisions between particles. 2. Surface Area: Increasing the surface a...
