Calcium carbonate

The reaction of soda ash (Na2CO3) with calcium sulfate in water is represented by the following chemical reaction: Na2CO3 + CaSO4 >>> CaCO3 + Na2SO4. Assuming that this reaction is complete and that there is 153 mg/l of CaSO4 initially present, what is the mass of soda ash that must be added to 1 liter of the water? How many grams of CaO are required to be the chemical equivalent of 246 g of Mg(HCO3)2? A complete reaction requires the number of CaSO4 to be equal to the number of moles…

Kidney stones are made from mineral and acid salts (Mayo Clinic). Kidney stones are often formed in our kidneys, usually because of urine becomes highly concentrated, which allow the minerals and salts to stick together and form the stone (Mayo Clinic. The picture below from the New York Times, shows where kidney stones are usually formed, in the major calyces, where they then travel down the ureter, where it usually becomes painful (NYT). There are several objectives to this experiment:…

hydrogen ion, creating HCO3, leaving the H+ ion to move around freely. This is known as ocean acidification and is responsible for the rise of acidity in the reefs.Ocean acidification are also changing the coral reefs and are exceeding rates of calcium carbonate: CaCO3. Symbiosis, where two organisms rely on each other for survival, is a basic example of the circle of life. Well the Coral Reefs are a circle and if you take out the reefs the organisms lose a home. This loss will leave the…

Introduction The seven soil formation factors have created unique soils throughout Saskatchewan. Through time soil processes such as additions, losses, translocation, and transformations have continued to form soils and make different horizons. Two catena's in Saskatchewan, one in the prairie and another in the boreal forest, were examined and classified into taxonomic group. The objective was to identify, compare, and contrast the major soil formation factors, morphological features, and…

Solutions should be the cations of cupric nitrate, ammonium nitrate, zinc nitrate, calcium nitrate, aluminum nitrate, silver nitrate, ferric nitrate, and plumbous nitrate. The other seven solutions should be the anions of sodium hydroxide, sodium carbonate, potassium sulfate, sodium iodide, sodium phosphate, sodium chloride, and sodium chromate. Divide students into groups of two. Provide a bin of paper towels for the…

of the abdominal cavity, under the liver. This is very common in females, contributing 10-20% of the adult population, (Kumar, (15-638), 2013). The pathophysiology of gallstones consists of variable proportions of cholesterol, calcium salts, such as phosphates, carbonates as well…

every living cell has water in it. Every living cell in surrounded by fluids. Water dissolves more substances then any other liquid. The ions dissolved in water are needed by organisms for growth and to manufacture various body substances. Every organism must keep it internal body fluids in balance in order to survive. Water uptake must balance water loss. Water- roots and root hair absorb water from the soil by osmosis. Roots are long and have a large surface area. Roots have thousand of root…

studies in preterm infants confirmed the diuretic effect of caffeine, and revealed a significant increase in creatinine clearance and urinary calcium excretion. The effect…

concentration of acid do to shells? Due to earth’s increasing carbon dioxide (CO2) rates scientists have shown that it can make shells , skeletons and corals up to one-third lighter in weight. As the ocean water becomes more acidic it lowers the calcium carbonate available to aquatic animals. ‘Scientists have predicted that the increase in ocean acidification could significantly reduce the ability of these creatures to build their casings, potentially devastating them and causing rippling…

many natural resources. But some of its natural resources are very rare and are very expensive. But on the other hand, they don’t have many needed resources such as wood, natural gas, and coal. The resources that Haiti has are bauxite, copper, calcium carbonate, gold, marble, and hydropower. Haitians pan for gold everyday just to find pieces of gold. Whenever they have spare time, they go to rivers and streams full of mud and start panning for gold. Panning for gold could be the extra dollar.…
