Calcium Equivalents

Calcium Equivalents. Calcium can be measured by the amount of the calcium salt (mg of the cation plus the anion or mL of a specified concentration) or the amount of elemental calcium in milligrams (mg) in milliequivalents (mEq) or in millimoles (mmol). (Because calcium has a valence of 2 the milliequivalents equals two times the number of

 · Calcium carbonate is inexpensive but is absorbed best when taken with food. Some over-the-counter antacid products such as Tums® and Rolaids® contain calcium carbonate. Each pill or chew provides 200–400 mg of calcium. Calcium citrate a more expensive form of the supplement is absorbed well on an empty or a full stomach.

Density Specific GravityWashington University in St

 · Density Density is the term for how heavy an object is for its size. Rock density is usually expressed in units like grams per cubic centimeter (g/cc or g/cm 3) kilograms per cubic meter or pounds per cubic inch (cubic foot or cubic yard). Rocks vary considerably in density so the density of a rock is often a good identification tool and useful for distinguishing terrestrial (Earth) rocks

Calcium carbonate (CaCO3) production of a subpolar

 · Rhodolith beds are major biogenic calcium carbonate producers with production rates that can be similar to those of coral reefs. Production rates vary latitudinally because of differences in abiotic and biotic drivers but the different methods used to estimate CaCO 3 production rate may also explain some of the wide variation among estimates. We used a 378-day manipulative experiment in a
