How many calcium ions in an 8.0 mole sample of calcium phosphate?
The formula unit for the most common form of calcium phosphate is Ca3(PO4)2. Therefore each formula unit, the ionically bonded counterpart of a mole for covalently bonded compounds, contains three calcium ions. The number of calcium ions in 8.0 "moles" of calcium phosphate is 3 [exact] X 8.0 X Avogadro's Number or 1.45 X 1025 atoms, where the depressed last digit of 1.45 indicates that this digit may not be significant. (The significant-digits-limiting datum is 8.0 moles.)
How many calcium ions in one mole?
A mole of calcium has 6.022 X 1023 calcium ions.
What are two ions that are needed for nerve transmission?
Not minerals, it is ions. Calcium ions and sodium ions.
How many charges does calcium have?
Calcium has a chrage of +2 or two positive charges
How many sodium ions are needed to balance the charge of one phosphate ion?
three sodium ions
Is calcium phosphate a group of ions?
Yes: calcium cations and phosphate anions.
What is the formula of the ionic compound that forms between calcium ions and phosphate ions?
Calcium phosphate is Ca3(PO4)2.
What is the mineral found in the bone?
Calcium
What is the formula for the compound made from calcium and mono hydrogen phosphate ions?
Calcium hydrogen phosphate :) Ca2HPO4
What is the chemical formula for calcium phosphate?
The chemical formula for calcium phosphate is:Ca3(PO4)2Ca has a charge 2+ and PO4 has a charge 3-, so you need 3 Ca and 2 PO4 to even out the positive and negative charges.
What is bone synthesis?
Precipitation of the salt calcium phosphate among fibers of the protein type I collagen. This results from raising the concentrations of calcium ions and phosphate ions beyond their "solubility product" concentration. This occurs next to special cells called osteocytes, and not inside their cytoplasm. Nobody has discovered the mechanism by which osteocytes pump high concentrations of calcium ions and also high concentrations of phosphate ions into the same locations. One theory is that a special protein ("osteoid") binds to both calcium ions and phosphate ions, so that they precipitate at concentrations that would not be high enough to cause precipitation if no osteoid were present. If you know how osteocytes cause bone synthesis, then you should publish this information in a refereed journal, such as Nature. akharris@bio.unc.edu
What is the balanced equation for calcium phosphate reacts with sodium carbonate in a double replacement?
Ca3(PO4)2 + 3Na2(CO3) --> 3CaCO3 + 2Na3PO4 (Phosphate ions have a 3- charge and carbonate ions have a 2- charge)

What ions are in copper phosphate?
There are three copper II ions (Cu2+) and two phosphate ions (PO43-).
What reactions occurs when calcium phosphate and sulfuric acid make calcuim sulfate and phosphoric acid?
The reaction between calcium phosphate and sulfuric acid, producing calcium sulfate and phosphoric acid is a double replacement. Notice in the chemical equation that the calcium and hydrogen ions switch partners with the SO42- and PO43- ions. The generic formula for a double replacement is AB + CD --> AD + CB Ca3(PO4)2 + 3H2SO4 --> 3CaSO4 + 2H3PO4
What is the formula for cadmium phosphate?
Dicalcium phosphate refers to Calcium Hydrogen-phosphate = CaHPO4
How does the phosphate buffer system help in maintaining the pH of our body?
The phosphate buffer system consists of two ions: dihydrogen phosphate ions and hydrogen phosphate ions. When the number of hydrogen ions in a body's bloodstream increases (pH drops), hydrogen phosphate ions accept hydrogen ions in order to maintain the equilibrium between the concentration of hydrogen and hydroxide ions within the bloodstream. When the number of hydrogen ions in the bloodstream decreases (pH increases), the resulting dihydrogen phosphate ions release hydrogen ions in order to increase the number of hydrogen ions in the blood.
