Question 2 (1 point)
Ca(OH)2(aq) + H2SO4(aq) → NRC
What is the double replacement reaction?

Answer 1

Ca(OH)₂ + H₂SO₄ → CaSO₄ + H₂O

Step-by-step explanation:

Chemical equation:

Ca(OH)₂ + H₂SO₄ → CaSO₄ + H₂O

Balanced chemical equation:

Ca(OH)₂ + H₂SO₄ → CaSO₄ + 2H₂O

The given reaction is double displacement reaction in which anion and cation of both reactant exchanged with each other. Calcium hydroxide react with sulfuric acid and form calcium sulfate and water.

Double replacement:

It is the reaction in which two compound exchange their ions and form new compounds.

AB + CD → AD +CB
