`(X)+K_(2)CO_(3)+"Air" overset("heat")(to)(Y)`
`(Y)+Cl_(2) to (Z)`pink
Which of the following is correct?

Options

A. X=black,`MnO_(2)`, Y=Blue, `CrO_(4)`, Z=`KMnO_(4)`
B. X=Green, `Cr_(2)O_(3)`, Y=Yellow, `K_(2)CrO_(4)`, Z=`K_(2)Cr_(2)O_(7)`
C. X=black, `MnO_(2)`, Y=green, `K_(2)MnO_(4)`, Z=`KMnO_(4)`
D. X=black, `Bi_(2)O_(3)`, Y=colourless, `KBiO_(2)`, Z=`KBiO_(3)`

Answer

C

Explanation

`underset(X)(2MnO_(2))+2K_(2)CO_(3) +underset("air")(O_(2)) overset(Delta)(to)underset("green Y")(2K_(2)MnO_(4)+2CO_(2)(uarr)`
`underset(Y)(2K_(2)MnO_(4))+Cl_(2) to underset("(Z) pink")(2KMnO_(4)) +2KCl`
