`CuSO_(4).5H_(2)O overset(1000^(@)C)(rarr)underset(("solide")("gas"))(A+B)+O_(2)`
`underset("bluish white")(CuSO_(4).H_(2)O)overset(x)(hArr)underset("white")(CuOS_(4))`here

A

`A=CuSO_(4)`

B

`A=CuO`

C

`B=SO_(2)`

D

`X=230^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
B,C,D
`underset("Blue")(CuSO_(4).5H_(2)O)overset("exposes")(hArr)overset("Pale Blue")(CuSO_(4).)3H_(2)Ooverset("100^(@)C")(hArr) underset("bluish white")(CuSO_(4).H_(2)O)overset(230^(@)C)(hArr)underset("white")(CuSO_(4))underset(Delta)overset(720^(@)C")(hArr)CuO+SO_(2)+(1)/(2)O_(2)`
Hence `A=CuO,B=SO_(2),X=230^(@)C`
