Compare and contrast the structures of Diamond and Magnesium in terms of the position and interactions of particles within the substance. Comment on how this is reflected in their properties.

Diamond is a giant covalent structure of Carbon atoms in which every atom makes 4 covalent bonds , each with another Carbon atom, forming a regular tetrahedral structure. This results in a very hard substanc...

In a titration, 45.0 cm^(3) of 0.100 mol dm^(-3) sodium hydroxide solution is exactly neutralised by 40.0 cm^(3) of a dilute hydrochloric acid solution. Calculate the concentration of the hydrochloric acid solution in mol dm^(-3).

First of all, summarise everything that you know in a table or in brief notes:NaOH, 45 cm^(3), 0.1 mol dm^(-3)HCl, 40 cm^(3)The first thing that you need to do is to find the number of moles of NaOH. This is...
