Yes.
No, melanin protects the skin from ultraviolet radiation. Vitamin D is synthesized in the skin and help with calcium absorption.
Tooth enamel (calcium phosphate) is the hardest substance found naturally in the human body. Unless you're wolverine, who contains adamantium. Or unless you swallow a diamond by accident.
Some alternative options to potassium iodide for radiation protection include Prussian blue, DTPA, and calcium. These substances can help remove radioactive particles from the body and reduce the risk of radiation exposure.
Calcium itself does not glow under a black light. However, some compounds containing calcium, such as certain phosphors, may exhibit fluorescence or phosphorescence under ultraviolet light, giving off a glowing effect.
No. It, in fact, is the opposite. Vitamin D is absorbed in the intestine, converted by UV radiation in the skin, and then helps absorb Calcium into the body. Vitamin D deficiency can be caused by a few things, a diet low in Vitamin D, low sun exposure, or it could be caused by a tumor in the parathyroid gland (but if you have low Calcium, that is not possible).
There is no elemental calcium in calcium oxide. Calcium oxide is a compound made up of calcium and oxygen atoms bonded together. When calcium oxide reacts with water, it forms calcium hydroxide, which contains calcium ions but not elemental calcium.
The word equation for the extraction of calcium from calcium oxide by electrolysis is: Calcium oxide (solid) -> Calcium (liquid) + Oxygen gas.
Diamond No its calcium.
the 3 elements found in calcium sulfate are calcium,sulfur and oxygen
calcium bicarbonate is the opposite of calcium, even though it has the same word on both words!
Calcium acetylene and calcium carbide are not the same. Calcium carbide is a chemical compound composed of calcium and carbon, while calcium acetylene is a gas produced when calcium carbide reacts with water. Calcium carbide is commonly used in the production of calcium acetylene for welding and cutting applications.
No, calcium oxide and calcium monoxide are not the same. Calcium oxide (CaO) is a compound formed from calcium and oxygen, where the calcium has a +2 oxidation state. In contrast, calcium monoxide (CaO) would suggest a +1 oxidation state for calcium, which is not a stable or common form. Therefore, calcium oxide is the correct term for the compound formed by calcium and oxygen.
