There are 4 easy steps to find the molar mass of Cr2(HPO4)3 based on its chemical formula. 1. Count The Number of Each Atom The first step to finding the molar mass is to count the number of each atom present in a single molecule using the chemical formula, Cr2(HPO4)3: ...
Enter the formula of a chemical compound to find the oxidation number of each element. A net ionic charge can be specified at the end of the compound between { and }. For example: ZnCl4{2-} or NH2NH3{+}. Enter just an element symbol to show the common and uncommon oxidation states ...
作者: Ray L Frost and Wayde Martens and Zhe Ding and J.Theo Kloprogge and Therese E Johnson 摘要: Infrared spectroscopy has been used to characterise synthesised hydrotalcites of formula MgxZn6−xCr2(OH)16(CO3) · 4H2O and NixCo6−xCr2(OH)16(CO3) · 4H2O. The infrared...

3.1. Global and Local Optimization Using Empirical and Ab Initio Energy Functions Global optimizations were performed on the energy landscapes using empirical potentials for various numbers of formula units per simulation cell and for slightly varying ionic radii, yielding a total of 5000 structure candi...
Spinels with the general formula CuCr2X4 (where X = S, Se, and Te) are ferromagnetic [1,2] and metallic conductors at room temperature [3]. CuCr2X4 spinels doped with 3d metals show a transition to the ferrimagnetic or antiferromagnetic order and the semiconductor state. Many of them exh...
