Answer 1

equations for last 3 are given below
molecular ;
Al + Fe(NO3)3 ---> Fe + Al(NO3)3
net ionic;
Al(s) + Fe3+(aq) ---> Al3+(aq) + Fe(s)
*****
molecular:
2Al(s) + 3Cu(NO3)2 ---> 3Cu(s) + 2Al(NO3)3
net ionic
2Al(s) + 3Cu2+(aq) ---> 3Cu(s) +2Al3+(aq)
****
2Al(s) + 3Zn(NO3)2---> 2Zn(s) + 2AL(NO3)3
2Al(s) + 3Zn2+(aq) ---> 3Zn(s) + 2Al3+(aq)
****
more reactive metal can replace another metal from its salt solution
Observing above table you can notice that Ca metal replaces
all other metals from their salt solution.So most reactive one is Ca
Then Mg replaces rest of the metals from their salt solution
Thus we can conclude metal reactivity is in following way
most reactive ---> least reactive
Ca > Mg > Al > Zn > Fe > Sn > Cu
