Marble and chalk or two forms of calcium carbonate. Equal masses of marble lumps and powdered Chalk are added to dilute hydrochloric acid. The marble takes longer than the chalk to fully react. Why is this so? (a) marble is more reactive than chalk (b) marble is more soluble than Chalk (c) The Marble has the smaller surface area than chalk.

The primary difference between limestone and marble is that limestone is a sedimentary rock composed primarily of calcium carbonate fossils. In contrast, marble is a metamorphic rock composed primarily of calcium carbonate fossils. Shells, sand, and muck descend to the bottom of oceans and lakes, where they solidify into limestone over time.
