Question

Match the statements in Column I with Column II($w,x,y,z$)

Answer 1

The balanced chemical reactions are as shown:

(A=4) $2Mn{O}_4^{-}\left(aq\right)$+$I{O}_3^{-}\left(aq\right)$+$2H_{2}O\left(l\right)$$⟶$ $Mn{O}_2\left(s\right)$+$3I{O}_4^{-}\left(aq\right)$+$2O{H}^{-}$
(B=3) $2Cu{\left(OH\right)}_2\left(s\right)$+$N_2{H}_2\left(aq\right)$$⟶$ $2Cu\left(s\right)+4H_{2}O\left(l\right)+N_2\left(g\right)$
(C=2) $Cr{O}_4^{2-}\left(aq\right)+3Fe{\left(OH\right)}_2\left(s\right)+4H_{2}O\left(l\right)$$⟶3Fe{\left(OH\right)}_3\left(s\right)+1Cr{\left(OH\right)}_4\left(aq\right)+{OH}^{-}\left(aq\right)$
(D=1) $1Cl{O}_4^{-}\left(aq\right)+2H_2{O}_2\left(aq\right)$$⟶1Cl{O}_2^{-}\left(aq\right)+2H_{2}O\left(l\right)+2O_2\left(g\right)$
