Calcium

Calcium Carbonate is insoluble chemical compound so all you have to do is decant or filter.... think about this, how do you separate sea shells from water? sea shells are made from calcium carbonate, that's why you see then on the beach all the time because they are insoluble.

Calcium hydroxide has molecular formula Ca(OH)2, so its elements are Calcium, Oxygen and Hydrogen.

high protein can lead to kidney stones.

high calcium can lead to deposits in bone joints. youll hear or feel your bones more.

Answer is Vitamin D.(1,25 bihydroxycholecalciferol. )

This used to be a very tough problem. Fortunately now made easier with a new chemical breakthrough. Spray Power Blue Scale Off directly onto the scaled over tile. Brush with a non-metallic pad type brush (like a scotch brite scrubby pad) what is begin to fizz, brush and spray till scale is all gone, then rinse.

You can google the name and buy it online.

There are several ways. Best that I now of is glass-beads-blasting. You need to have a good Pool Service person do this. THEN you should balance the water (especially TA) to prevent the same thing happening again. We can supply more info through discussion.

Calcium carbonate (CaCO3) consists of one calcium ion (Ca2+) and one carbonate ion (CO3^2-). Therefore, the percentage of calcium ions in calcium carbonate is calculated as: (Atomic mass of calcium / Molecular mass of calcium carbonate) x 100 = (40.08 / 100.09) x 100 = 40.02% Therefore, calcium ions make up approximately 40.02% of the total mass of calcium carbonate.

Ca2+

No, it is not. All oxides are insoluble except for group I oxides

yes it is found in lime yes it is found in lime.

I know there are many other diseases and things that will take the calcium from the bones. But the only one I am very familiar with is hyperparathyroidism. Its basically a problem with the parathyroid gland. It takes calcium out of the bones and puts more into the blood. Thus causing weak bones. Im going to the doctor to get tested for this soon.

Phosphorus is an essential mineral that is required by the body to function normally. It is mainly found in the body in the form of phosphates. Phosphorus is a critical component of all living organisms since it performs very important functions

you need to do what is called a back-titration, by reacting the seashell (ground up very fine) with an acid, then titrating the solution with a base. the data can then be used to find the moles of CaCo3, and from there you can go to grams. Divide grams CaCo3 by the mass of seashell used, then multiply by 100 to find the percentage

See http://www.fiu.edu/~pricer/Calcium%20Carbonate.pdf.

The solubility of CaCO3 depends on the solubility of CO2. The solubility of gases decreases in water as the temperature rises. This behavior is discussed at http://antoine.frostburg.edu/chem/senese/101/solutions/faq/temperature-gas-solubility.shtml.

YES

Oxidation state: +2

Ionic charge: +2

Double hydroxided alkaline

Metallic solid state

Reactive with (hot) water or steam

Calcium Carbonate - CaCO3

This is found in rocks such as limestone and is the main component of seashells

Calcium Chloride - CaCl2

This is a salt which is found naturally in very small quantities

Calcium Hydroxide - Ca(OH)2

My understanding is that this does not occur naturally, it is very useful in many industries

Calcium Oxide - CaO

Created during the decomposition of limestone

To name a few.

Anytime of the day is OK.

Actually if you're working out. The best time to take vitamins or supplements is within an hour after your workout. The reason is because after a good workout and cardio session, your glycogen or body sugar is all but depleted and your muscles will act like a sponge and absorb and replenish the vitamins and amino acids burnt up during rigorous exercise. For sedentary people, anytime is fine.

Yes. Eggshells are composed of approximately 95% calcium carbonate (CaCO3). One average 5.0 gram egg shell shells out 2.0 grams of calcium.

Milk and and all dairy products(cheese, yogurt) are rich in calcium. If you do not enjoy consuming those foods than try taking calcium supplements. They have them in chewable "candies."

Cheese, milk, yogurt and other dairy products are rich in calcium. Sesame seeds, tofu, dried herbs, almonds, flax seeds, brazil nuts, herring fish and green leafy vegetables such as kale are also high in calcium.

Because Calcium helps you absorb Vitamin D. It also tastes good, so try for 2-4 servings a day, even though recommendation is only 2-3, so drink 3-5 a day, k?

Calcium is good for your bones teeth and you need calcium in you or your bones and teeth will start to disintegrate and u will be ugly and have no friends .

Ca(OH)2 + H2SO4 --> CaSO4 + 2H2O

Acid base neutralization reaction producing a salt and water.

CaO + H 2 SO 4 = CaSO 4 + H 2 O

My book says that calcium is paramagnetic but I cannot understand why since it doesn't have any unpaired electrons as paramagnetic materials need to have. I have the same question for magnesium too.

Calcium Chloride is bascially salt. It is very corrosive to steel.
