XC l _ 2 (excess) + YC l _ 2 → XC l _ 4 + Y ↓ YO → _ > 400^ o ^ Δ...
\text{YO}\mathop{→}_{\text{> }{\text{400}^{o} \textC^{Δ} \dfrac{1}{2} {O}_{2} \text{+Y}, Ore of Y would be
Options
- ASiderite
- BCinnabar
- CMalachite
- DHornsilver
Correct answer
B. Cinnabar
Step-by-step solution
The reaction sequence is as follows
\text{HgO}\mathop{→}_{\text{>}{\text{400}^{o} \textC^{Δ} \text{Hg}\text{+}\dfrac{1}{2} {O}_{2}
\text{HgO}\mathop{→}_{\text{>}{\text{400}^{o} \textC^{Δ} \text{Hg}\text{+}\dfrac{1}{2} {O}_{2}
