I am presented with the problem of deriving a method to find out what products are formed in the thermal decomposition of copper carbonate CuCO3. The two possible equations for this reaction are: 1 2CuCO3s Cu2Os + 2CO2g + 1/2O2g 2 CuCO3s CuOs + CO2g I will use the volume of gas produced to check which equation is right this is explained further on. Testing the gases limewater or burning splint released may seem less cumbersome however there is a possibility of the gas produced being a mixture of carbon dioxide and oxygen hence testing...
The boiling tube is heated over the wire mesh because of safety reasons, for example to prevent the tube from possible breakage under the heat. Also precaution must be taken when working around the bunsen flame.

Additionally to this, if any water is spilt when setting up the inverted measuring cylinder or at any other time, then it must be wiped and dried instantly in order to prevent any accidents or injuries for example slipping.

Goggles must be worn at all times during the practical and long hair must be tied back to prevent any accidents.
