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 ...
Enter the molecular formula of the substance. It will calculate the total mass along with the elemental composition and mass of each element in the compound. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N,...

Maruyamaite has an ideal chemical formula of K(MgAl2)(Al5Mg)(BO3)3(Si6O18)(OH)3O and is a unique K-dominant tourmaline species. Currently the occurrence of maruyamaite is limited from the Kokchetav Massif. Moreover, no K-... R Shimizu - 《Pediatric Emergency Care》 被引量: 0发表...
The experimental results of Seebeck value were close to calculated results by the extended Heikes formula confirming of the strong correlation effect. In addition, the Mg-doped CuCrO2resulted in increased electrical conductivity and reduced thermal conductivity with increasing temperature. These indicate ...
O2 Mg2+ Ion An ion is a particle that has a net electrical charge. An ion with a positive charge is called a proton and an ion with a negative charge is called an anion. When a stable atom gains or loses electrons then it is called an ion. ...
The new general formula of the group proposed by Hatert et al. [11] is [A2A2′][A1A1′A1″2]M1M22[XO4]3 (X = P5+, As5+), where A sites may be either vacant or partially filled, depending on the cation substitution. The small pentovalent cations X and large variable-valence ...
Therefore, the unit cell of the LiNbO3:Gd3+(0.003):Mg2+(0.65 wt.%) crystal, such as the unit cell of the ferroelectric phase of the nominally pure LiNbO3 crystal, is characterized by the space symmetry group C36V (R3c) and contains two formula units (10 atoms) [2]. In this case,...
The general formula of MXene can be expressed as Mn+1XnTx, which can be prepared by etching the precursor MAX phase (Mn+1AXn). M represents a transition metal element, A is aluminum or silicon, and X repre- sents a carbon or nitrogen element. Tx is a surface functional group of MX...
Chemical, thermal, and X-ray analysis of the compound lead to the formula: \\((Mg_{0.741}Al_{0.259}(OH)_{2})((Fe^{II}(CN)_{6})_{0.067}(CO_{3})_{0.002}(H_{2}O)_{1.05})\\)The compound is dehydrated at 100° to 250°C, and the adsorption of N2, O2, CO2, and H2...
