Respuesta :

Explanation:

1.

YES

K2SO4(aq) + Ba(NO3)2(aq) --> Ba(SO4)2(s) + 2KNO3(aq)

Net ionic equation

2SO4^2-(aq) + Ba2+(aq) --> Ba(SO4)2(s)

2.

NO

No precipitate is formed because KNO3, MgSO4, K2SO4 and Mg(NO3)2 all are soluble.

3.

YES

BaCl2(aq) + Na2(SO4)(aq) --> BaSO4(s) + 2NaCl(aq)

Net ionic equation:

Ba2+(aq) + SO4^2-(aq) --> BaSO4(aq)

4.

Ni2+(aq) + S2-(aq) ---> NiS(s)

Precipitates are formed only if the products are insoluble. as follows:

  1. A precipitate is formed and the net ionic equation is: SO₄²⁻ (aq) + Ba²⁺ (aq) --> Ba(SO₄)₂ (s)
  2. No precipitate is formed
  3. A precipitate is formed and the net ionic equation is: SO₄²⁻ (aq) + Ba²⁺ (aq) --> Ba(SO₄)₂ (s)
  4. The net ionic equation is: Ni²⁺ (aq) + S²⁻ (aq) ---> NiS (s)

Will a precipitate form if solutions of potassium sulfate and barium nitrate are combined?

A precipitate is formed when solutions of potassium sulfate and barium nitrate are combined because the product barium sulfate is insoluble.

The net ionic equation of the reaction is as follows:

SO₄²⁻ (aq) + Ba²⁺ (aq) --> Ba(SO₄)₂ (s)

Will a precipitate form if solutions of potassium nitrate and magnesium sulfate are combined?

No precipitate will be formed in this case because all the ions are soluble.

Will a precipitate form if solutions of barium chloride and sodium sulfate are combined?

Yes a precipitate is formed because barium sulfate is insoluble.

The net ionic equation is as follows:

SO₄²⁻ (aq) + Ba²⁺ (aq) --> Ba(SO₄)₂ (s)

What is the net  ionic equation for the precipitation of nickel(II) sulfide?

The net ionic equation for the precipitation of nickel(II) sulfide is as follows:

Ni²⁺ (aq) + S²⁻ (aq) ---> NiS (s)

Therefore, precipitates are formed only if the products are insoluble.
