They pump hydrogen ions (H +) out of this space to produce more carbonate ions (CO 3 2-) ions that bond with (Ca 2+) ions to make calcium carbonate (CaCO 3) for their skeletons. Because there are more HCO 3 - ions but fewer CO 3 2- ions in acidified seawater, the corals have to expend more energy to pump out H + ions from …

The base of pastel chalks is calcium sulfate (CaSO 4 ), which is derived from gypsum (CaSO 4 -2H 2 O), an evaporite mineral formed by the deposition of ocean brine; it also occurs disseminated in limestone. Chalk and dehydrated gypsum thus have similar origins and properties. Pastels also contain clays and oils for binding, and strong pigments.
