A traction motor core consists of a stator*stacked on the outside and a rotor*on which the drive motor rotates. The core is made in different heights and sizes depending on the output structure, such as hybrid and pure electric vehicles. When electricity is transmitte...
The addition of hydroiodic acid to a silver nitrate solution precipitates silver iodide according to the reaction: AgNO3(aq)+HI(aq)-->AgI(s)+HNO3(aq) When 50.0 mL of 5.00* 10-2M AgNO3 is combined wi An excess of aqueous AgNO_3 reacts with 24.5 mL of 5 M K_2CrO_4(aq) to f...
If they react with oxygen they are converted into a form that plants can’t use. They can also interact with other ions which may cause them to precipitate as solids, making them unavailable to plants. This is the point in the story where chelates become important. Chelates are organic ...
A good yield of rhombic crystals of the copper ammonium salt is secured, the crystals tending to smaller size than those secured by the use of ammonia and acetic acid. While the process has been described with particular reference to the copper ammonium salt of diazo amino tetrazole, it is...

(TF), and the antioxidant capacity of 20 varieties of seeds and sprouts of quinoa extract. Quinoa seeds were germinated for 72 h and dried in an oven at 45 °C. The extracts were obtained by dynamic extraction using methanol. Phytochemical analysis with liquid chromatography coupled with mass ...
Pi was reacted with ammonium molybdate. The content of free and total inorganic phosphorus was measured as absorbance of molybdenum blue at a wavelength of 655 nm using a UV-Vis spectrometer (BMG Labtech, SPECTROstar Nano, Ortenberg, Germany). To quantify phytic acid in each sample a standard...
