Correct answer: D
The eggshell is primarily composed of calcium carbonate (CaCO₃).
When sulphuric acid (H₂SO₄) reacts with calcium carbonate, the reaction produces:
Calcium sulfate (CaSO₄)
Water (H₂O)
Carbon dioxide gas (CO₂)
Chemical Equation
The gas evolved is carbon dioxide (CO₂).
Therefore, the correct answer is Carbon dioxide gas.
