Question
For the reaction: $MnO_2 + 4HCl \rightarrow MnCl_2 + Cl_2 + 2H_2O$
Answer: A,B,C,D
💡 Solution & Explanation
$Mn(+4 \rightarrow +2)$ is reduced (oxidizing agent). $Cl(-1 \rightarrow 0)$ is oxidized (reducing agent). 1 mole $MnO_2$ gives 1 mole $Cl_2$ (22.4 L). Molar mass $MnO_2 = 87$ g; $4 \times HCl = 4 \times 36.5 = 146$ g.
