500g of zinc carbonate was heated to constant mass.A.state what was observed? write an ionic equation that took place? calculate the apparent loss in mass?

    Your post isn't quite clear. What DID YOU OBSERVE? I don't know what you saw.
    ZnCO3 ==> ZnO + CO2
    What do you mean by APPARENT loss in mass. It either lost mass or didn't lose mass. There is nothing apparent about it.
