Calcium

potassium in a metal while oxygen is a non-metal therefore pottasium oxide has ionic bond

If you put water into water, it would eventually get mixed.

Fresh water is less dense than salt water and fresh water from rain or rivers will "float" on underlying salt sea water.

Water of different temperature and different salinity have different densities and do make layers in the oceans and lakes of the world.

Ordinary water will usually mix rather than separate, unless it is frozen into ice, which is less dense than liquid water.

There is also "heavy water" that has deuterium in the place of ordinary hydrogen and is ABOUT 11% denser than ordinary water, which will float above it.

Yes, but often imperfectly and it takes a great deal of time. Cartilage tends to have a very poor blood supply, so it takes a long time for the cells to gather enough nutrients to build more matrix and repair the damage. If the damage was too severe, the cartilage will not have time to repair the damage before bony changes take over and prevent a return to normal function.

I would imagine you are talking about breaking down and building up of bone. Osteoclasts, and osteoblasts. Two types of cells that are constantly breaking down and rebuilding bone. Osteoclasts break down the bone acidically. While osteoblasts rebuild bone, by secreting osteoid, that becomes mineralized.

Ha, I had this exact same question in my AP Chem Class, stumped me for a minute too. 6CaO + P4O10 → 2 Ca3(PO4)2

Calcium is a chemical element, you typically take it in the form of the salt Calcium Carbonate. It is not a vitamin. It is typically referred to as a mineral.

Calcium is in group 2 of the periodic table. The group consists of beryllium, magnesium, calcium strontium, barium and radium. Calcium is in period 4.

Calcium is an important mineral that the human body needs; it is present in bones and has a number of other functions as well. However, calcium comes in a variety of forms, not all of which are equally beneficial to the body. Metallic calcium would react with water to form calcium hydroxide, a powerful base with a very high pH which can dissolve flesh. Even then, I would not describe calcium hydroxide as poisonous so much as corrosive, but it could be lethal in any event. There are also other calcium compounds which are poisonous, not because of the calcium but because of the other component of the compound, for example, calcium cyanide.

The body's calcium level is regulated by a gland in the endocrine system, it is called the Parathyroid Gland.

Because if you over correct, excess calcium carbonate is all but harmless, whilst excess sodium hydroxide can be corrosive and toxic.

Sulfur, and Oxygen. Formula

CaSO4...

Ca (charge 2+) is ionically bonded to the SO4, which has a -2 charge, two of the oxygens are double bonded to the sulfur and another two oxygens are single bonded to the Sulfer.

There are several different conditions that can cause calcium deposits in the eye. These include hypocalcemia, gout, renal failure, and chronic inflammation.

Three hormones: parathyroid hormone, calcitonin and 1,25 dihydroxycholecalciferol (the active from of Vitamin D). These three hormones act on bone, the kidneys and the small intestine to keep calcium balance in you r body.

Calcium is important for healthy bone and tooth. But excessive presence of calcium in blood may cause some problems, such as tiredness, loss of appetite, vomiting.etc. It may also cause diarrhea leading to dehydration and thirst. Sometime with high calcium in blood may cause confusion and a person may become unconscious. High calcium level in blood may indicate excessive secretion of parathyroid hormone which should be treated. High calcium in blood also indicate bone disease. Excessive drinking of milk and frequent intake of antacids can increase calcium level in blood.

When calcium bicarbonate is heated, it decomposes into calcium carbonate, carbon dioxide, and water. The chemical reaction can be represented as 2 Ca(HCO₃)₂ → CaCO₃ + 2 CO₂ + H₂O. This process is often observed in nature, such as in the formation of stalactites and stalagmites in caves. The release of carbon dioxide gas can be seen as bubbling during the reaction.

eggs and milk contains a lot of calsium

Ca + 2HNO3 --> Ca(NO3)2 + 2H ...i think...?

tropomyosin moves out of the groove between the actin molecules.

The sarcoplasmic reticulum is known for its storage of calcium ions in muscle cells.

Calcite is one of the most abundant minerals on Earth. Thousands of products including decorations and building materials to natural physical features of the Earth.

zinc nitrate + sodium hydroxide yields sodium nitrate and zinc hydroxide( white precipitate)
