Calcium

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)

Potassium iodide is neutral. So any solution of potassium iodide would have a pH of 7.

One note: no substance has a particular pH as pH depends on both the acidity/basicity of a substance and how concentrated it is.

Yes, you can take too much calcium, according to Dr. Toohey, who says that 2500 mg. is the maximum amount one should consume, whether by diet or supplements. You can read about Dr. Toohey's opinion here: http://www.chronicfatigue.org/What's%20New.html Evidently when you take in too much calcium, it can cause other health problems such as kidney stones. It is best to get your calcium from food sources, as they are absorbed into the body better. Ruth Hendrickson

Yes, butter has calcium, even though you should not use it as a primary source for your calcium.

Too much calcium will result in a high pH. This will cause the nutrients to become too concentrated and they will eventually kill the plant.

Yes,Sorel in 1867 announced the discovery of an excellent cement formed from the combination of magnesium oxide and magnesium chloride solution. This cement type is known by many different names, such as Sorel, magnesite and magnesium oxychloride cement. This cement has many superior properties to Portland cement. However, there are two other known magnesia cements. The first is magnesium oxysulfate (MOS), which is the sulfate analogue of magnesium oxychloride and is formed by the combination of magnesium oxide and magnesium sulfate solution. The second is magnesium phosphate cement (MAP), formed by the reaction between magnesium oxide and a soluble phosphate, such as ammonium phosphate monobasic (NH4H2PO4)

We can find calcium as a non metal element. Atomic number of it is 20.

The radius of a cadmium atom is smaller than the radium of a mercury atom. The trend for atomic radius is that the radius becomes larger toward the left side of the row and toward the bottom of the group.

Calcium carbide lamps have been used (historically in mines) to create light by immersing calcium carbide in water to produce acytelene gas, which burns and creates light. Although they work as lamps, the gas produced by them makes them less safe than oil lamps, and as such they were usually only used in industrial lighting rather than in homes. Electrical lighting is usually safer than either oil or carbide lamps because there is less danger of fire.

yes-potassium will blow up on contact with air or water and other materials or elements. potassium forms many compounds such as potassium chloride, which is a lethal poison used to kill people on death row in the united states. potassium is important in your diet, as it helps carry nerve impulses to and from your brain. potassium is commonly found in bananas. potassium is more reactive than even sodium.
