The chemical equation representing the reaction of Ba^{2+} with each of the given ions is:

(1) Ba^{2+}(aq)+S^{2-}(aq)-->BaS(s)

(2)Ba^{2+}(aq)+2OH^{-}-->Ba(OH)_{2}(aq)

(3)Ba^{2+}(aq)+CO_{3}^{2-}(aq)-->BaCO_{3}(s)

(4)Ba^{2+}(aq)+SO_{4}^{2-}(aq)-->BaSO_{4}(s)

Sulfates, carbonates, phosphates, sulfides, and chromates of barium are insoluble. whereas acetates, nitrates, hydroxides, and chlorides of barium are soluble.

Therefore, among the compounds formed from the given ions barium sulfide, barium carbonate and barium sulfate are insoluble.

Hence, the correct options are (1) S^{2-} (3) CO_{3}^{2-} (4) SO_{4}^{2-}

Only Ba(OH)2 is soluble in water. BaS, BaCO3, and BaSO4 are precipitates.
(2) OH- is the correct answer.

jasenka [17]

Answer is: dispersion forces.

The London dispersion force is the weakest intermolecular force.

Dispersion force is also called an induced dipole-induced dipole attraction.

The London dispersion force (intermolecular force) is a temporary attractive force between molecules.

The dipole beetween iodine and bromine is weak.

Lisa [10]

Answer:

2H+(aq) + 2OH-(aq) → 2H2O(l)

Explanation:

Step 1: The balanced equation

2HCl(aq)+Ca(OH)2(aq) → 2H2O(l)+CaCl2(aq)

This equation is balanced, we do not have the change any coefficients.

Step 2: The netionic equation

The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will.

2H+(aq) + 2Cl-(aq) + Ca^2+(aq) + 2OH-(aq) → 2H2O(l) + Ca^2+(aq) + 2Cl-(aq)

After canceling those spectator ions in both side, look like this:

2H+(aq) + 2OH-(aq) → 2H2O(l)
