Write the balanced net ionic equation, including the phases, for the given reaction. A solution of Ba ( OH ) 2 and a solution of H 2 SO 4 are mixed. Water and a precipitate of BaSO 4 are formed.

Ba²⁺(aq) + 2OH⁻(aq) + 2H⁺(aq) + SO₄²⁻(aq) → 2H₂O(l) + BaSO₄(s)

Explanation:

The net ionic equation is a chemical reaction that shows only the chemical species that are involved in the reaction.

A solution of Ba(OH)₂ [Ba²⁺ + 2OH⁻], and H₂SO₄ [2H⁺ + SO₄²⁻] produce H₂O and BaSO₄(s). The reaction is:

Ba²⁺(aq) + 2OH⁻(aq) + 2H⁺(aq) + SO₄²⁻(aq) → 2H₂O(l) + BaSO₄(s)

As you can see, all ions are involved in the reaction and you must write all them.

I hope it helps!

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

the answer is 0.42 is that is an option. this question provides no info
