Chemistry

Answer:

2. Option B.

Explanation:

H₂SO₄ + Ba(OH)₂ → BaSO₄ + 2H₂O

You can count 2H in sulfuric acid and 2 H in the barium hyrdoxide, so the coefficient for water must be 2.

You will have 4 H on both sides of the reaction.

Try with the dissociations of each reactant

Sulfuric acid ⇒ H₂SO₄ →  2H⁺  + SO₄⁻²

Barium hydroxide ⇒ Ba(OH)₂ → Ba²⁺  +  2OH⁻

Sulfate anion bonds to barium cation to produce the salt, therefore the 2 protons will bond the 2 hydroxide in order to produce, 2 moles of H₂O

2H⁺ + 2OH⁻ → 2H₂O
