Question 21

An ore of chromium contains chromium(III) oxide, Cr2O3\text{Cr}_2\text{O}_3Cr2​O3​. Chromium can be extracted from this oxide by heating it with carbon.

Balance the equation for this reaction.

2Cr2O3+………C→………Cr+………CO2 2\text{Cr}_2\text{O}_3 + \dots\dots\dots\text{C} \rightarrow \dots\dots\dots\text{Cr} + \dots\dots\dots\text{CO}_2 2Cr2​O3​+………C→………Cr+………CO2​
