Answer #1

To be able to predict these reaction you have to consult the activity series.

https://en.wikipedia.org/wiki/Reactivity_series

The activity series is a useful guide for predicting the products of metal displacement reactions.

A metal in the activity series will displace any metal ion BELOW it in the activity series. Al is above Ag so it will displace Ag from AgNO3.

Al + 3AgNO3 Al(NO3)3 + 3Ag

Also it will displace Cu ion.
2Al + 3CuSO4 Al2(SO4)3 + 3Cu

Similarly it will displace Pb ion

2Al + 3Pb(NO3)2 2Al(NO3)3 +3Pb

Note that it will NOT displace Ca ion or Na ion since both Ca and Na are ABOVE Al in the activity series.
