ZanzabumX [31]

Answer:

In the above reaction, sulfur dioxide and oxygen react together to form sulfur trioxide. This means that an increase in pressure would move the equilibrium to the right and result in more sulfur trioxide being formed. Pressure can only affect the position of equilibrium if there is a change in the total gas volume.

Reduce the following equation to a net ionic equation: 2Na+ + SO4^2- + Ba^2+ + 2Cl^- ---> 2Na^+ + 2Cl^- + BaSOv4
Eduardwww [97]

net ionic equation

B) SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)

Explanation:

We have the following chemical equation:

2 Na⁺ (aq) + SO₄²⁻ (aq) + Ba²⁺ (aq) + 2 Cl⁻ (aq) → 2 Na⁺ (aq) +  2 Cl⁻ (aq) + BaSO₄ (s)

To get the net ionic equation we remove the spectator ions and we get:

SO₄²⁻ (aq) + Ba²⁺ (aq) → BaSO₄ (s)

were:

(aq) - aqueous

(s) - solid
