Question

Powdered ${\mathrm{CaCO}}_3$ reacts more rapidly than flaky ${\mathrm{CaCO}}_3$ because of?

Answer 1

The surface area of powdered and flaky calcium carbonate.

• Calcium carbonate is a chemical compound with a chemical formula ${\mathrm{CaCO}}_3$.
• It is a common substance found in rock in all parts of the world and is the main component of shells of marine organisms, snails, pearls, and eggshells.
• Powdered ${\mathrm{CaCO}}_3$ reacts more rapidly than flaky ${\mathrm{CaCO}}_3$ because of the difference in the surface area.
• Powdered ${\mathrm{CaCO}}_3$ have more surface area than flaky ${\mathrm{CaCO}}_3$

Therefore, powdered ${\mathrm{CaCO}}_3$ reacts more rapidly than flaky ${\mathrm{CaCO}}_3$ because of the larger surface area.
