Question

A substance X reacts with water to form an alkali Y. Substance 'Y' produces an insoluble shiny solid 'Z' when it reacts with one of the components of Earth's atmosphere. Identify X', "Y', 'Z' and give all the chemical equations for the reactions involved in the process.​

Answer 1

Answer:

The substance X is Calcium Oxide (CaO).

The substance Y is Calcium Hydroxide(Ca(OH)2).

The substance Z is Calcium carbonate (CaCO3).

Calcium oxide reacts with water to form calcium hydroxide . Calcium

Hydroxide reacts with carbon dioxide present in the atmosphere to form calcium carbonate which has shine.
