The largest and strongest muscle in this group is the subscapularis muscle. This triangle shaped muscle begins in the scapula, located on the underside of the shoulder blade, and extends up to the humerus, located on the front of the upper arm.
The most important inorganic phosphate is calcium phosphate, Ca3(PO4)2. It makes up the larger part of phosphate rock, a mineral that is abundantly distributed throughout the world. Ca(H2PO4)2, is a compound produced by treating rock phosphate with sulfuric acid or phosphoric acid, or a mixture of the two.
From a practical standpoint, inorganic chemicals are substances of mineral origin that do not contain carbon in their molecular structure and are typically based on the most abundant chemicals on earth: oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium.
