Hey MATE!

(1) a) It is a correct reaction because Silver is above Copper in reactivity series which proves that silver can replace copper.

b) It is wrong because Zinc is more reactive than copper and therefore copper can never displace zinc.

c) It is wrong because Silver is less reactive than hydrogen and therefore silver cannot displace hrydrogen.

d) Yes it is a correct equation as Aluminium comes before Iron in reactivity series and has the ability to displace Iron easily.


(2) The values of P, Q, R and Z are in above image .

P *R/Q+Z ===> 2*4/1+1 => 8/2 ==> 4 Answer .


3) FeSO4 has been oxidized to Fe(SO4)2 as extra oxygen has been added to it.


Hope it helps
