Complete and balance the following equations

(ⅰ )${\mathrm{AgNO}}_3+\mathrm{HCl}\to ........+.......$

(ⅱ)${\mathrm{Na}}_2{\mathrm{SO}}_3$ + $\mathrm{HCl}$ $\to$$.......+........+......$

(ⅱⅰ) ${\mathrm{NaHCO}}_3$ + $\mathrm{HCl}$ $\to$$......+.....+......$

(ⅳ) $\mathrm{FeS}$+ $\mathrm{HCl}$$\to$$.......+......$

Reactions of Hydrochloric acid

(ⅰ ) ${\mathrm{AgNO}}_3\left(\mathrm{aq}\right)$ + $\mathrm{HCl}\left(\mathrm{aq}\right)$ $\to$ $\mathrm{AgCl}\left(\mathrm{s}\right)$ + ${\mathrm{HNO}}_3\left(\mathrm{aq}\right)$

(Silver nitrate) (Hydrochloric acid) (Silver chloride) (Nitric acid)

(ⅱ) ${\mathrm{Na}}_2{\mathrm{SO}}_3\left(\mathrm{s}\right)$ + $2\mathrm{HCl}\left(\mathrm{aq}\right)$ $\to$ ${\mathrm{SO}}_2\left(\mathrm{aq}\right)$ + $2\mathrm{NaCl}\left(\mathrm{s}\right)$ + ${\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$

(Sodium sulfite) (Hydrochloric acid) (Sulphur dioxide) (Sodium chloride)( Water)

(ⅱⅰ) ${\mathrm{NaHCO}}_3\left(\mathrm{s}\right)$ + $\mathrm{HCl}\left(\mathrm{aq}\right)$ $\to$ $\mathrm{NaCl}\left(\mathrm{s}\right)$ + ${\mathrm{CO}}_2\left(\mathrm{g}\right)$ + ${\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$

(Sodium bicarbonate)(Hydrochloric acid) (Sodium chloride)(Carbon dioxide)(Water)

(ⅳ) $\mathrm{FeS}\left(\mathrm{g}\right)$ + $2\mathrm{HCl}\left(\mathrm{aq}\right)$ $\to$ ${\mathrm{FeCl}}_2\left(\mathrm{s}\right)$ + ${\mathrm{H}}_2\mathrm{S}\left(\mathrm{g}\right)$

(Iron sulfide) (Hydrochloric acid) (Ferrous chloride) (Hydrogen sulfide)

So here Hydrochloric acid react with Silver nitrate , Sodium sulfite and Sodium bicarbonate , Iron sulfide to give various products, like Silver chloride , Sulphur dioxide and Sodium chloride and Ferrous chloride.
