An element occupies group no.13 and period number 2 is an representative element of that group reacts with carbondioxide and forms an oxide (A). (A) reacts with `CuSO_(4)` give blue beads (B). Identify the element compound (A) and (B). Write the reaction.

Text Solution

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)`
