How can Diamond and Graphite both be made of carbon but be so different?

Graphite and Diamond are different because they have different structures. Both have Giant Covalent Structures, resulting in very high melting temperatures. However each carbon atom in Diamond has 4 coval...

0.120g of an ideal gas was introduced into a gas syringe. The volume occupied by the gas at a pressure of 1.02x10^5 Pa and temperature 20 degrees was 49.3 cm^3. Calculate the molar mass of the gas.

The ideal gas law is PV=nRT, and we know that we can achieve the molar mass through the relationship of; n=m/mr. When using the ideal gas law it is essential that we use SI units before we begin plugging ...

How would you synthesise an carboxylic acid just from a primary haloalkane like bromoethane?

Nucleophilic substitution using NaOH to convert haloalkane to primary alcohol. This is a mechanism that you need to know for the exam. Then oxidise the alcohol by refluxing with acidified potassium dichro...

What are the half equations representing the changes of Pb2+ and Br- in the electrolysis of lead bromide?

Pb2+ + 2e- -> Pb 2Br- -> Br2 + 2e- Lead ions undergo reduction (gain of electrons) at the negative electrode to form solid lead. Bromide ions undergo oxidation (loss of electrons) at the positive el...
