${\mathrm{Ag}}_2\mathrm{S}$ ore is mixed with NaCl and heated to 600°C , in the presence of air then products formed are

The chemical equation for the reaction of ${\mathrm{Ag}}_2\mathrm{S}$  Ore with NaCl in presence of air the products are

${\mathrm{Ag}}_2\mathrm{S} + 2\mathrm{NaCl}+2{\mathrm{O}}_2\to 2\mathrm{AgCl}\downarrow +{\mathrm{Na}}_2{\mathrm{SO}}_4$
