Investigating the thermal decomposition Of Zinc Carbonate Znco3 heat Zno + Co2 (Td) Aim:- To relate the amount of zinc carbonate heated to the amount of zinc oxide produced. Planning:- The variables in this experiment are the heat, the amount of time you heat it for. The variable that I am going to investigate is the heat (temperature) of the Bunsen burner. This can be varied by having it on the blue roaring flame, (which is the hottest_ or the yellow safety flame (which is the coolest). From this it can make the zinc carbonate decompose quicker depending on which flame you use. So if it is on the yellow safety flame the zinc carbonate will take a longer time than it would if you were to use the blue roaring flame I will make sure that my experiment is a fair test by:- when I weigh each test tube make sure...
