Составьте уравнения химических реакций ионного обмена. Определите, между какими веществами идет реакция, и составьте уравнения в полном и ионном сокращенном виде. а) Na2S и MnSO4 б) HGCL и Fe(NO3)2 в) KOH и H2SO3 ДАЮ 50 БАЛЛОВ пожалуйста Решите

Answer 1

Ответ:

a) Na2S + MnSO4 = Na2SO4 + MnS↓

2Na(+) + S(-2) + Mn(2+) + SO4(2-) = 2Na(+) + SO4(2-)+ +MnS↓

S(-2) + Mn(2+) =MnS↓

б)HgCl2 + Fe(NO3)2 → Hg(NO3)2 + FeCl2

Hg(2+) + 2Cl(-) + Fe(2+) + 2NO3(-) = Hg(2+) + 2NO3(-) + Fe(2+) + 2Cl(-)

в) H2SO3 + KOH = K2SO3 + H2O

2H(+) + SO3(2-) + K(+) + OH(-) = 2K(+) + SO3(-) + H2O

2H(+) + K(+) + OH(-) = 2K(+) + H2O

Answer 2

Ionic Exchange Reactions and Equations

Ionic exchange reactions involve the exchange of ions between two compounds. To determine the reaction and write the balanced equations in both complete and ionic shortened forms, we need to identify the compounds involved and their respective ions.

a) Na2S and MnSO4: The reaction is between sodium sulfide (Na2S) and manganese(II) sulfate (MnSO4).

The balanced equation in complete form is: 2 Na2S + MnSO4 → Na2SO4 + MnS

The balanced equation in ionic shortened form is: 2 Na+ + S2- + Mn2+ + SO42- → 2 Na+ + SO42- + MnS

b) HgCl and Fe(NO3)2: The reaction is between mercury(I) chloride (HgCl) and iron(II) nitrate (Fe(NO3)2).

The balanced equation in complete form is: HgCl + Fe(NO3)2 → Hg(NO3)2 + FeCl2

The balanced equation in ionic shortened form is: Hg+ + Cl- + Fe2+ + 2 NO3- → Hg2+ + 2 NO3- + FeCl2

c) KOH and H2SO3: The reaction is between potassium hydroxide (KOH) and sulfurous acid (H2SO3).

The balanced equation in complete form is: 2 KOH + H2SO3 → K2SO3 + 2 H2O

The balanced equation in ionic shortened form is: 2 K+ + 2 OH- + H2SO3 → K2SO3 + 2 H2O
