Pearls, urchin spines, the shells of mussels, snails and clams, even coral— all these structures are made out of the same chemical compound: calcium carbonate. So how does this single ingredient form such a vast array of materials? Rob Ulrich investigates....
Remove your exhaled carbon dioxide. This is accomplished through the use of a cannister of sodium hydroxide (Sofnolime). The carbon dioxide (gas) reacts with sodium hydroxide and calcium hydroxide to form calcium carbonate (solid). Replace oxygen that you have consumed. Small tanks of pureoxygen...
It does this using processes that are also seen in bones and seashells. Around the egg is a membrane, and evenly spaced on the membrane are points where columns of calcite (a form of calcium carbonate) form. These columns stack together side by side to form the shell. According to an in...

sea-dwelling creatures are particular wizards: microscopic coccolithophores, coral-building algae, and giant snails engineer their own building material, like magic, by pulling two dissolved chemicals — calcium and carbonate — out of the water to form solid shells of, surprise, calcium carbonate....
and draws it through corrugated sheets of plastic sprayed with a hydroxide solution. The CO2 absorbs into a liquid film to form a carbonate solution which goes through a pellet reactor, using chemistry common in water treatment, to form calcium carbonate pellets “like hailstones” that molecularly...
Agate, tiger's-eye, and amethyst are materials that sometimes form in volcanic landscapes. They can be heated if the rock units that contain them are overrun by a lava flow or if a magma body intrudes above or below. The altered identity of these stones is considered to be "natural."...
Answer to: Calcium carbonate degrades to form carbon dioxide and calcium oxide. How many grams of calcium carbonate are needed to form 3.45 L of...
carbonate and calcium chloride to form calcium carbonate precipitate, which is then dehydrated, dried and crushed. Because the settling volume of light calcium carbonate (2.4-2.8 ml / g) is larger than that of heavy calcium carbonate (1.1-1.9 mg / L), it is called light calcium carbonate. ...
How does acid rain affect coral reefs?Corals:Coral reefs are built by marine animals called corals. They take in minerals from the sea water and use this to create calcium carbonate, which they use to build their skeletons. Calcium carbonate also is used by clams, snails, mussels, and ...
