Question

what kind of reaction occurs when calcium hydroxide reacts with carbon dioxide​

Answer 1

Answer:

A double displacement reaction occurs when calcium hydroxide reacts with carbon dioxide.

Explanation:

Calcium hydroxide reacts with carbon dioxide in the presence of air to form a white precipitate of calcium carbonate and water. It is used in the whitewashing of walls. The balanced chemical equation for the reaction is as follows:

$Ca(OH)_{2} +CO_{2}$ → $CaCO_{3} + H_{2} O$

Here two compounds react by an exchange of ions to form two new compounds. So this is a double displacement reaction.
