This is quite a complicated sounding question but it is actually quite simple if you break it down! Start by writing a balanced equation for the reaction:

3H₂ (g) + ...

Diamond has a giant structure of carbon atoms held together by strong covalent bonds:  - Diamond is made up of many strong covalent bonds, so a lot of energy is needed to overcome them, so diamond has a h...

Background Information

This is a neutralisation reaction between an acid (sulfuric acid) and a base (copper carbonate). When a carbonate reacts with an acid, the products...

Conduction is possible as delocalised (free) electrons are able to carry a charge and move through the metal.

Covalent bonding relies on the fact that all atoms are desperately trying to get a full outer shell of electrons. By full outer shell we mean 2 electrons in the first shell, 8 in the 2nd shell, 8 in th...
