Question

Complete the following chemical equations and balance them -

${\mathrm{Fe}}_2{\mathrm{O}}_3+\mathrm{\_\_}\stackrel{\mathrm{heat}}{\to }\mathrm{\_\_}+\mathrm{CO}$

• A. 3C
• B. 2Fe

Answer 1

• The oxides of metals that lie below Aluminium in the activity series can be reduced using reducing agents like carbon in the form of coke.
• The chemical reaction - ${\mathrm{Fe}}_2{\mathrm{O}}_3+\mathrm{C}\stackrel{\mathrm{heat}}{\to }\mathrm{Fe}+\mathrm{CO}$

Final answer: The balanced chemical equation will be

${\mathrm{Fe}}_2{\mathrm{O}}_3+3\mathrm{C}\stackrel{\mathrm{heat}}{\to }2\mathrm{Fe}+3\mathrm{CO}\uparrow$
