Answer 1

The correct answer is both salt and water.

Key Points

Calcium hydroxide, also known as slaked lime, reacts with carbon dioxide in a chemical reaction.
The chemical reaction can be represented as: Ca(OH)₂ + CO₂ → CaCO₃ + H₂O.
In this reaction, calcium carbonate (CaCO₃) is formed, which is a type of salt.
Additionally, water (H₂O) is produced as a byproduct.
This reaction is significant in various applications such as carbon capture and in the construction industry for making lime mortar.

Additional Information

Salt
- In chemistry, a salt is an ionic compound that can be formed by the neutralization reaction of an acid and a base.
- Salts are composed of related numbers of cations (positively charged ions) and anions (negatively charged ions) so that the product is electrically neutral.
Metal
- A metal is an element that readily forms positive ions (cations) and has metallic bonds.
- Examples include iron, gold, and aluminum.
Water
- Water (H₂O) is a molecule composed of two hydrogen atoms covalently bonded to one oxygen atom.
- It is essential for all forms of life and is a common solvent used in many chemical reactions.
