Question

$MnO_2 + HCl \xrightarrow{ \Delta } A(g)$
$ A(g)+ F_{2 {\text{(excess)}}} \xrightarrow{573 \, K} B(g)$
$B(l)+ U(s)\rightarrow C(g)+D(g)$
The gases $A, B, C$ and $D$ are respectively

• A. $Cl_2, ClF_3, UF_6, ClF$
• B. $O_2, O_2F_2, U_2O_3, OF_2$
• C. $Cl_2, ClF, UF_6, ClF_3$
• D. $O_2, OF_2, U_2O_3, O_2F_2$

Answer 1

Answer: (A)

$MnO _{2}+4 HCl \longrightarrow \underset{(A)}{ Cl _{2}}+ MnCl _{2}+2 H _{2} O$

$Cl_2 + \underset{\text{in excess}}{F_2} \longrightarrow \underset{(B)}{CIF_3}$

$3ClF_ 3 +\longrightarrow \underset{(C)}{UF_6} + \underset{(D)}{3ClF}$
