Answer:

A.Cl2+2KI→2KCL+I2

b.C2H5OH+3O2→2CO2+3H2O+HEAT

Cu, Fe, Zn and Al is the correct order if all of these are arranged in their increasing order of reactivity. In any reaction, Copper is the least reactive. ... Then comes Aluminium which is highly reactive and is the most reactive of all elements. So the order will be Cu, Fe, Zn, Al.
