I hope this answer helps you

Answer 2

Eggshell reacts with sulphuric acid to produce calcium oxide along with the evolution of carbon dioxide gas.

• Eggshells are rich in calcium carbonate, which reacts with sulphuric acid.
• Calcium carbonate is a compound with the molecular formula, CaCO₃.
• It reacts with sulphuric acid to form a salt calcium sulfate, water, and carbon dioxide gas.
• The reaction involves the displacement of the anion part of the compounds.

                       $CaCO_{3} + H_{2} SO_{4}$ → $CaSO_{4} + H_{2} O + CO_{2}$
