Calcium

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

You can get calcium from dairy products such as milk, yogurt, and cheese, as well as from leafy green vegetables, tofu, and fortified foods like orange juice and cereals. Additionally, you can also find calcium in fish with edible soft bones, such as sardines and canned salmon.

Calcium is calcium-it is its own nutrient.

The atomic number of calcium is 20. The atomic number tells you the number of protons in the nucleus of a calcium atom, which also corresponds to the number of electrons in a neutral calcium atom.

Calcium is an essential mineral in biology that plays a crucial role in many physiological processes. It is important for bone health, muscle function, nerve transmission, and cell signaling. The body tightly regulates calcium levels to ensure proper function of these processes.

The LD50 of calcium is the amount of calcium that would be lethal to 50% of the test population. The LD50 value for calcium can vary depending on the form of calcium, but generally, it is considered to be relatively high. Ingesting extremely high doses of calcium supplements can lead to toxicity symptoms like kidney stones, constipation, and heart rhythm abnormalities.

To find the number of moles in 5000 grams of calcium, you need to divide the given mass by the molar mass of calcium. The molar mass of calcium is approximately 40.08 g/mol. So, 5000 grams of calcium is equal to 5000/40.08 = 124.69 moles of calcium.

Yes, calcium is an essential mineral for cats as it helps maintain healthy bones and teeth. Cats can get calcium from their diet, typically from sources such as bone meal, dairy products, and fish. It's important to ensure that cats have a balanced diet to meet their calcium needs.

Calcium carbonate is a common calcium supplement that is inorganic and poorly absorbed, while calcium lactate is an organic form of calcium that is more easily absorbed by the body. Calcium carbonate is typically found in antacids, whereas calcium lactate is commonly used in food fortification and as a dietary supplement.

Calcium hydroxide is an ionically bonded compound that dissolves in water to form a strong alkali; calcium carbonate is an ionically bonded compound that dissolves in water to form a weakly alkaline solution.

No, calcium itself is not a neurotransmitter BUT it is highly important in the process of the action potential. The action potential triggers the influx of calcium at the end of the terminal bouton, causing the influx of Ca2+ into the cell and this triggers for the release of the neurotransmitter. :)

Calcium itself does not tarnish. However, calcium compounds or alloys may undergo oxidation or corrosion, which can lead to tarnishing. For example, calcium metal can react with oxygen in the air to form calcium oxide, a process known as oxidation.

Mining calcium, often in the form of limestone, can have various environmental impacts such as habitat destruction, groundwater contamination, and air pollution from dust and greenhouse gas emissions. It may also contribute to soil erosion and disrupt local ecosystems. Implementing sustainable mining practices and reclamation efforts can help mitigate these negative impacts.

Calcium was discovered by Sir Humphry Davy in 1808 through the process of electrolysis. He isolated calcium metal by passing an electric current through molten calcium chloride. This discovery helped in understanding the nature of elements and their properties.

No, calcium sulfate and calcium sulphate are the same chemical compound, commonly known as gypsum. Calcium sulfate dihydrate specifically refers to the hydrated form of calcium sulfate, where each molecule contains two molecules of water (CaSO4 ∙ 2H2O).

The molar mass of calcium bromide (CaBr2) is 199.89 g/mol. Calcium has a molar mass of 40.08 g/mol. The mass percent of calcium in calcium bromide is calculated as (40.08 g/mol / 199.89 g/mol) x 100%, which is approximately 20.04%.

No, calcium is a mineral that plays crucial roles in the body's structure and functions, particularly in bone health and muscle contraction. DNA, on the other hand, is a molecule that carries genetic information in cells. They are completely different entities with different functions in the body.

Calcium chloride contains around 36-40% elemental calcium by weight. This means that for every 100 grams of calcium chloride, there would be approximately 36-40 grams of elemental calcium. It is important to consider this when calculating the actual amount of calcium being consumed from calcium chloride supplements or additives.
