There are two ways to get magnesium sulfate salt. Draw up the reaction equations in molecular and ionic form.

There are two ways to get magnesium sulfate salt. Draw up the reaction equations in molecular and ionic form. Calculate the amount of the substance acetylene with a volume of 67.2.

Magnesium sulfate MgSO4 can be obtained by

– interaction of sulfuric acid with magnesium;

– interaction of magnesium oxide with sulfuric acid.

Mg + H₂SO₄ = MgSO₄  + H₂.

Mg⁰ + 2H¹⁺ + SO₄^2- = Mg²⁺ + SO₄ ^2- + H₂⁰.

Mg⁰ + 2H¹⁺  = Mg²⁺ + H₂⁰.

MgO + H₂SO₄ = MgSO₄  + H₂O.

MgО + 2H¹⁺ + SO₄^2- = Mg²⁺ + SO₄ ^2- + H₂О.

MgО + 2H¹⁺ = Mg²⁺ + H₂О.

No. 2.

n = V: Vn.

n = 67.2 L: 22.4 L / mol = 3 mol.

Answer: 3 mol.
