Ames Research Center (ARC), commonly known as NASA Ames, is a major NASA research center at Moffett Federal Airfield in California's Silicon Valley.
It consists mostly of the minerals gibbsite Al(OH) 3, boehmite Î³-AlO(OH) and diaspore Î±-AlO(OH), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase TiO 2.n 2009, Australia was the top producer of bauxite with almost one-third of the world's production, followed by China, Brazil, India, and Guinea. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.
Solution. Potassium ions have a charge of 1+, while sulfate ions have a charge of 2â. We will need two potassium ions to balance the charge on the sulfate ion, so the proper chemical formula is K2SO4. Calcium ions have a charge of 2+, while nitrate ions have a charge of 1â.We will need two nitrate ions to balance the charge on each calcium ion. The formula for nitrate must be enclosed in parentheses. Thus, we write Ca(NO3)2 as the formula for this ionic compound. chemical formula is a concise list of the elements in a compound and the ratios of these elements. To better understand what a chemical formula means, we must consider how an ionic compound is constructed from its ions.
