Write a balanced chemical equation for the followings

(a) Solid lead (II) sulfide reacts the aqueous hyrobromic acid (HBr) to form solid lead(II) bromide and dihydrogen monosulfided gas.

(b) sulfur dioxide gas reacts with oxygen gas to form sulfur trioxide gas

(c ) aqueous potassium hydroxide with aqueous iron (III) chloride to form solid iron (III) hydroxide and aqueous potassium chloride

Solutions

Expert Solution

a. Solid lead (II) sulfide reacts the aqueous hyrobromic acid (HBr) to form solid lead(II) bromide and dihydrogen monosulfided gas.

PbS(aq) + 2HBr(aq)---------> PbBr2(s) + H2S(g)

(b) sulfur dioxide gas reacts with oxygen gas to form sulfur trioxide gas

b. 2SO2(g) + O2(g) -------------> 2SO3(g)

(c ) aqueous potassium hydroxide with aqueous iron (III) chloride to form solid iron (III) hydroxide and aqueous potassium chloride

c. 3KOH(aq) + FeCl3(aq) ------------> Fe(OH)3(s) + 3KCl(aq)
