Verified by Experts

As per the position in the periodic table this element which occupies group number 13 and period number 2 is boron and it reacts with `CO_(2)` to form boric oxide
1) `3CO_(2)+4Brarr2B_(2)O_(3)+3C`
`therefore` the compound A is `B_(2)O_(3)`
2) `B_(2)O_(3)` reacts with `CuSO_(4)` to form `underset(("Red"))((CuBO_(2))_(2))`
`CuSO_(4)+B_(2)O_(3)rarrCu(BO_(2))_(2)+SO_(3)`
`therefore` the compound B is copper bead. `Cu(BO_(2))_(2)`
