Nostrana [21]

Answer: Pb(NO_3)_2(aq)+2KI(aq)\rightarrow PbI_2(s)+2KNO_3(aq)

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.

The double displacement reaction in which one of the product is formed as a solid is called as precipitation reaction.

The balanced molecular equation is:

Pb(NO_3)_2(aq)+2KI(aq)\rightarrow PbI_2(s)+2KNO_3(aq)

RideAnS [48]

The amount ( in moles  of excess  reactant that is left is 0.206 moles


Explanation

FeS(s)  + 2HCl  (aq) →  FeCl2 (s)  + H2S (g)

  • by use of mole ratio of FeS: HCl which is  1:2 this means that  0.223 mole  of FeS  reacted  completely with 0.223   x   2/1 =0.446  moles  0f FeCl2.

  • HCl was in  excess because  0.446 moles of HCl reacted and initially  there was  0.652  moles.
  • Therefore the  amount that was left

      = 0.652- 0.446  =0.206  moles
