Question

$MnO_2 + HCl { ->[\Delta] } A(g)$ $A(g)+ F_{2 {\text{(excess)}}}->[573 \, K] B(g)$ $B(l)+ U(s)\rightarrow C(g)+D(g)$ 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)

$Cl_2, ClF_3, UF_6, ClF$

Answer 2

$MnO _{2}+4 HCl \longrightarrow \underset{(A)}{ Cl _{2}}+ MnCl _{2}+2 H _{2} O$ $Cl_2 + \underset{\text{in excess}}{F_2} \longrightarrow \underset{(B)}{CIF_3}$ $3ClF_ 3 +\longrightarrow \underset{(C)}{UF_6} + \underset{(D)}{3ClF}$
