The thermal decomposition (heating) of metal carbonates will produce CO2 as, in thermal decomposition, the substance being heated will break down into simpler substances.
Method
- Put some copper(II) carbonate (its a green powder, if your wondering) into a test tube and insert a bung with a delivery tube at the top
- Clamp the test tube at a 90º angle and insert the delivery tube into another test tube (that is positioned vertically)
- Heat the copper(II) carbonate with a bunsen burner.
NOTE: Because CO2 is denser than air, the downward delivery method can be used.
Equations
Copper(II) carbonate ---> copper oxide + carbon dioxide
CuCO3(g) ---> CuO(s) + CO2(g)
A blog covering and explaining the Edexcel IGCSE Chemistry specification for the 2016 summer exams. If you are doing just double science, you do not need to learn the stuff for paper two, if you are doing triple you will need to learn all (GOOD LUCK!) I have separated the papers to make files easier to find. Hope it helps :)
