Write the Chemical Equation for the Reduction of Cr₂O₃ to Chromium

Multiple Choice

Write the chemical equation for the reduction of Cr₂O₃ to chromium with silicon as the reducing agent.

A) Si(s) + Cr₂O₃(s) → SiO₃(s) + Cr(l)
B) Si(s) + Cr₂O₃(s) → SiO₂(s) + 2 CrO(s)
C) 3 Si(s) + 2 Cr₂O₃(s) → 3 SiO₂(s) + 4 Cr(l)
D) 3 Si(s) + Cr₂O₃(s) → 3 SiO(s) + 2 Cr(l)
E) 4 Si(s) + Cr₂O₃(s) → SiO₃(s) + 2 CrO(s)
