Answer #1

answer : firstly its ammonium carbonate (NH4)2CO3 and its a group reagent for group IV ( Cations of this group are calcium(II), strontium(II), and barium(II) )

procedure for this group test is like To the solution add (NH4)2CO3 in excess, in the presence of NH4Cl if elements (cations) belongs to this group then they form precipitate .

so yes D and G belongs to same group ( group IV) whereas E whhich remain unchanged don't belong to this group

this group is not preodic table group this is cation analysis group
