The phosphomolybdate ion, [PMo 12 O 40] 3−. Ammonium phosphomolybdate is the inorganic salt of phosphomolybdic acid with the chemical formula (NH 4) 3 PMo 12 O 40. The salt contains the phosphomolybdate anion, a well known heteropolymetalate of the Keggin structural class.
4 Cr (bath) + 3 O 2 → 2 Cr 2 O 3 Cr 2 O 3(slag) + 3 C (bath) → 3 CO (gas) + 2 Cr (bath) To drive the reaction to the forming of CO, the partial pressure of CO is lowered using argon or nitrogen. Since the AOD vessel is not externally heated, the blowing stages are also used for temperature control. The burning of carbon increases the bath ...
A (4+3) cycloaddition [1] is a cycloaddition between a four-atom π-system and a three-atom π-system to form a seven-membered ring. Allyl or oxyallyl cations (propenylium-2-olate) are commonly used three-atom π-systems, while a diene (such as butadiene ) plays the role of the four-atom π-system.
This means that each photon emitted at the photosphere suffers an average of less than one scattering before it reaches the observer. At the temperature at optical depth 2/3, the energy emitted by the star (the original derivation is for the Sun) matches the observed total energy emitted. [citation needed] [clarification needed]
Making a saline water solution by dissolving table salt in water.The salt is the solute and the water the solvent. In chemistry, a solution is defined by IUPAC as "A liquid or solid phase containing more than one substance, when for convenience one (or more) substance, which is called the solvent, is treated differently from the other substances, which are called solutes.
A device with AOD enabled keeps a limited portion of the screen on during sleep mode.An Always-On Display may display a set of recent push notifications in place of a notification tone or LED signal, as well as information such as the time, date, and battery status of the device; they often may also be configured to also show various types of notifications as they arrive, or screensavers.
Fehling's solution is prepared by combining two separate solutions: Fehling's A, which is a deep blue aqueous solution of copper(II) sulfate, and Fehling's B, which is a colorless solution of aqueous potassium sodium tartrate (also known as Rochelle salt) made strongly alkaline with sodium hydroxide. These two solutions, stable separately, are ...
The AOD (automatic overdrive) is a four-speed automatic transmission, with the 4th gear as overdrive. Introduced in 1980, it was Ford 's first four-speed automatic overdrive transmission. The gearset design is based on the Ford "X" automatic transmissions used during the 1950s, '60s, and '70s.
