Calcium

calcium bicarbonate is the opposite of calcium, even though it has the same word on both words!

Calcium chloride contains only two elements, calcium and chlorine, while calcium chlorate contains these two elements plus oxygen. The chlorine and oxygen in calcium chlorate are combined in a polyatomic ion with formula ClO3-1.

Doctors recommend people over 45 to consume more calcium-rich foods like milk to help prevent osteoporosis, a condition where bones become weak and brittle. Adequate calcium intake can help maintain bone density and reduce the risk of fractures and other bone-related issues as people age.

0.625 moles Ca3N2 (3 mole Ca/1 mole Ca3N2)(6.022 X 10^23/1 mole Ca)

= 1.13 X 10^24 calcium ions

No. Dolomite is a mineral rock that is primarily composed of calcium carbonate but contains many other compounds including magnesium carbonates and oxides of silicon, aluminium, iron lithium, titanium, chromium, manganese, sodium, potassium and lithium.

First you need to find how many moles of calcium that is. Since 1 mole of calcium is 40.078g you need to divide 60.8g by how much is one mole (60.8 / 40.078 = 1.517 moles). Once you know how many moles you have (1.517) you can find how many particles there are. There are 6.02 *10^23 atoms in one mole (Avagadro's number), so your final answer will be, 6.02*10^23 x 1.517 = 9.132 * 10^23

No, calcium chloride and calcium hypochlorite are not the same. Calcium chloride is a chemical compound used for de-icing roads and in food preservation, while calcium hypochlorite is a chemical compound used as a disinfectant and bleaching agent, such as in swimming pools.

Excess calcium is stored in the bones when blood calcium levels increase. This process is regulated by hormones such as calcitonin and parathyroid hormone, which help maintain calcium balance in the body.

Yes - you can have an allergic reaction to calcium carbonate. It's derived from oyster shells. Stop taking calcium carbonate and seek emergency medical attention if you experience a rare allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives). Other, less serious side effects may be more likely to occur. Continue to take calcium carbonate and notify your doctor if you experience nausea or vomiting; decreased appetite; constipation; dry mouth or increased thirst; or increased urination. Some drugs will affect calcium carbonate - before taking it tell your doctor if you are taking digoxin, antacids containing calcium or aluminum; calcitriol or vitamin D supplements; a tetracycline antibiotic such as tetracycline, demeclocycline, doxycycline, minocycline, or oxytetracycline (all these have various brand names). Drugs other than those listed here may also interact with calcium carbonate. Talk to your doctor or pharmacist before taking any other prescription or over-the-counter medicines, including vitamins, minerals, and herbal products.

Calcium sulfide has a chemical formula of CaS, which means one calcium atom is combined with one sulfur atom. The molar mass of calcium sulfide is 72.14 g/mol, with calcium contributing 40.08 g/mol. Therefore, the percent composition of calcium in calcium sulfide is approximately 55.6%.

With the addition of calcium in steel, the steel suppress the formation of MnS during the solidification of steel. Other reasons include:

1.Improving steel castability in continuous casting

2. To minimize inclusion related surface defects in billet, bloom and slab castings

3. To Improve steel machinability at high cutting speeds

4. To minimize the susceptibility of steel to re-heat cracking

5. To prevent lamellar tearing in large restrained welded structures

6. To minimize the susceptibility of high-strength low alloy linepipe steels to hydrogen-induced cracking.

Calcium trisodium is a chemical compound that is used as a chelating agent, helping to bind and neutralize metal ions in various industrial processes. It is commonly used in water treatment, food preservation, and medical applications.

Calcium is an element so it does NOT have any formula. But it has a symbol Ca. It is very reactive to be found in nature as free element, so it occurs as compound which contain Ca2+ ions, like CaCO3(limestone) and CaSO4(gypsum).

A calcium ion is Ca2+ and has 18 electrons and 20 protons. A calcium atom is Ca and has 20 electrons and 20 protons. So the ion has the same number of protons pulling a smaller number of electrons closer to the nucleus and so the ion is smaller.

NO, Calcium is divalent. It is having 2 valence electrons

Calcium deficiency may be more common than realized; lime is often desirable to reduce soil acidity and because of other indirect benefits.

To balance the equation for the reaction between calcium oxide and tetraphosphorus decoxide to form calcium phosphate, you need to first write the unbalanced equation: CaO + P4O10 -> Ca3(PO4)2

Next, balance the equation by ensuring the same number of atoms of each element on both sides of the equation: 3CaO + P4O10 -> Ca3(PO4)2

Steel does not naturally contain calcium as an intentional alloying element. The main components of steel are iron and carbon, along with other elements like manganese, silicon, and sometimes nickel and chromium. However, trace amounts of calcium may be present as an impurity depending on the source of the raw materials used in steel production.

Yes, calcium salts are inorganic compounds because they do not contain carbon-hydrogen (C-H) bonds. They are typically formed by the reaction of calcium with various acids to produce salt compounds containing calcium ions. Common examples include calcium chloride and calcium carbonate.

To make anhydrous calcium chloride from calcium oxide, you would react calcium oxide with hydrochloric acid (HCl). This reaction will yield calcium chloride and water. The water produced in the reaction will need to be removed to obtain anhydrous calcium chloride.

Yes, my science teacher said that it was, and im pretty sure it is too...

Limestone is primarily composed of calcium carbonate. However, calcium sulfate is not typically found in limestone; it is a separate mineral known as gypsum.

One mole of anything, no matter what the element is, is Avogadro's number, which is 6.02 * 10^23 atoms.

One mole of Calcium is equal to it's atomic weight in grams :

1 mole Ca = 40.08 g = 6.02 * 10^23 atoms

There is a 1000mg in a gram. 1000mg * 40.08g =

=40,080mg of Ca per mole

If you have 8.6mg of Ca that is 8.6mg / 40,080mg = .00021457 of a mole of calcium

so just multiply that by Avogadro's number to give you number of atoms:

.00021457 * 6.02 * 10^23 atoms = 1.292 * 10^20 atoms of Ca
