I thought group 2 means group II in the periodic table and same for group I ???
Also could u give me the products of:
Acid + Base -->
Acid + Metal -->
Acid + Metal carbonate -->
Sorry for all the trouble :(

if lead is above hydrogen in the reactivity series then why is lead formed instead of hydrogen in the electrolysis of aqueous lead nitrate ????

By the way when u have any AQ solutions then what u do is that u gotta kno the followin rules
1. when the metal is Cu or Ag then they go to the Cathode but if other metals hence they form metal hydroxide
2.if the gas is a halogen then it goes to the Anode ...if not a halogen then OH- goes to the Anode givin out Oxygen .i'll give u the formula , wait
4OH- --> 2H2O +O2+4e-

your right....group I is 1, group II is 2, and so on
acid + base = salt + water
acid + metal = salt + hydrogen
acid + carbonate = salt + carbon dioxide + water

Thanks dude ;)
