  1. I am not sure but I think you got them right.  To be absolutely sure take a look at a periodic table.  there are some website that you go to through google that will help you put the information together.  


  2. lead (II) carbonate was added to nitric acid

    PbCO3 + 2HNO3 ---> Pb(NO3)2 + H2O + CO2

    Aluminium was added to Hydrochloric acid

    2Al + 6HCl ---> 2AlCl3 + 3H2
