Given
the following Activity Series:
Li
> K > Ba > Sr >
Ca > Na > Mg > Al > Mn > Zn > Fe
> Cd > Co > Ni >
Sn > Pb > (H) > Cu
> Ag > Hg > Au
Given
the following Active Metals:
Li
> K > Ba > Sr >
Ca > Na
Complete
the products of the following reactions, then balance the equation (If no
reaction write NR):
ANSWERS:
1. Cu (s) + Al(NO3)3 (aq)
-----> No Reaction
(Copper is less
active than aluminum)
2. 2 Al (s) + 3 Cu(NO3)2 (aq) -----> 2 Al(NO3)3
(aq) + 3 Cu
(s)
3. Au (s)
+ H2SO4 (aq) -----> No
Reaction
(Gold is below (H) in the activity Series above)
4. Ca (s)
+ 2 HOH
(l) -----> Ca(OH) 2 (aq) +
H2 ↑
5.
Mn (s) + H2O
(l) -----> No Reaction
(Manganese is not listed as an
Active metal above)
