Question

Complete the following chemical equations and balance them -

${\mathrm{SnO}}_2+\mathrm{\_\_\_\_}\to \mathrm{\_\_\_}+\mathrm{CO}$

• A. 2C
• B. Sn

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.
• Thus, the complete chemical reaction is ${\mathrm{SnO}}_2+\mathrm{C}\to \mathrm{Sn}+\mathrm{CO}$

Final answer: The balanced chemical equation is:

${\mathrm{SnO}}_2+2\mathrm{C}\stackrel{\mathrm{heat}}{\to }\mathrm{Sn}+2\mathrm{CO}\uparrow$
