In the normal spinel The oxygens form a cubic close packed array The Mg(II) (A-type) sit in tetrahedral sites The Al(III) (B-type) sit in octahedral sites i.e. [MII]tet[MIIIMIII]ohO4 An inverse spinel is an alternative arrangement where half of the trivalent ions swap with the divalent ions so that the Mg(II) now occupy octahedral sites ie B(AB ...
The anion gap can also be used to differentiate cations and anions in urine using the following equation Anion gap is most commonly performed for patients who present with altered mental status, unknown exposures, acute renal failure, and acute illnesses.

Um sistema tampão mantém um pH quase constante porque neutraliza pequenas quantidades de ácido ou base adicionadas à solução. No nosso corpo, o pH é mantido em torno de 7,4 por vários pares de tampões que impedem a acidose (pH sanguíneo abaixo de 7,35) como também a alcalose (pH acima de 7,45), pois a morte pode resultar de aumentos ou de diminuições relativamente pequenas de pH.

It consists of the cation trans-[CrCl 2 (H 2 O) 4] + and additional molecules of water and a chloride anion in the lattice. Two other hydrates are known, pale green [CrCl(H 2 O) 5]Cl 2 • H 2 O and violet [Cr(H 2 O) 6]Cl 3. Similar behaviour occurs with other chromium(III) compounds. Preparation
Rule 1- While naming a coordination compound cation is always named before the anion irrespective of the fact that whether complexion is cation or anion. Rule 2- If there are more than one type of ligands present in any coordination compound, the name of the ligands is to be done in alphabetic...
In addition to ionic liquids with discrete anions, the electrodeposition of a range of metals has been previously carried out in deep eutectic solvents (DESs).5 These comprise of quaternary ammonium salts (e.g. choline chloride, ChCl), metal salts or metal salt hydrates and hydrogen bond donors (e.g...
The ions O2-, F, Na+, Mg2+ and A13+ are isoelectronic, their ionic radii showa) A significant increase from 02- to A13+b) A Significant decrease from 02- to A13+c) An increase from O2-to F and then decrease from Nat to AB+d) A decrease from 02- to F an then increase from Nat to AB+

Metal Ions In Crystals, Academic Press, New York, 1970. 1 This is not surprising since the simple electrostatic theory neglects all covalent bonding and attempts to describe the many electron and, often, the many atom ligands as just point charges or dipoles. Molecular orbital theory, which takes account of ligand-metal

The correct answer may be - [CrCl₂(H₂O)₅]Cl.H₂O. Since the question says that AgNO₃ has been used to precipitate 1 mol of AgCl, it means that 1 Chlorine atom has been There are one cation and one anion which corresponds to a total of two ions which show conductivity.
