yes...make sure u revise the state symbol balanced equation for the thermal decompsition of carbonates, percentage error, stoichiometric calculations, effect of surface area on ROR, moles of liquids, solids and gases and how to deduce moles from an equation...RMM, how to work out which group 2 metal is present in the carbonate; given the RMM of the carbonate... hope that helps x
