The Polanyi dilute-diffusion-flame method has been applied to the magnesium-oxygen system. Diffusion flames were obtained at pressure of a few mm Hg by carrying magnesium vapor in an argon stream into an atmosphere of oxygen-argon. Photographic photometry was used to measurer reaction rates. The...
1镁在空气中燃烧生成氧化镁这一化学变化:①用中文表达是:镁+氧气→氧化镁;②用英语表达是:magnesiun+OXYgen→magnesiumOXide③用化学用语表达是:2Mg+O2 点燃 . 2MgO比较上述三种表达方式,说明国际通用的化学用语表达式的优势: . 2镁在空气中燃烧生成氧化镁这一化学变化:①用中文表达是:镁+氧气→氧化镁;②用英...
(such as those ofcalcium,magnesium, and iron) and as saltlike compounds that may be regarded as formed from the acidic and basic oxides, as sulfates, carbonates, silicates, aluminates, and phosphates. Plentiful as they are, these solid compounds are not useful as sources of oxygen, because ...

aPiper diagram of hydrochemical facies of each groundwater sample (circles) visualizing calcium/sodium mass ratio used as a proxy for geochemical evolution, i.e., residence time/age. Na: sodium, K: potassium, Ca: calcium, Mg: magnesium, Cl−: chloride, SO42−: sulfate, CO32−: carb...
and the bound protein complexes were washed twice with distilled water and resuspended with 25 μl LONP1 degradation buffer containing 30 mM NaCl, 10 mM HEPES-potassium hydroxide buffer (pH 8.0), 2 mM magnesium chloride, 0.1 mg ml−1 BSA, 4 mM ATP and 100 nM LONP1. ...
Magnesium has been introduced into silicon containing oxygen by diffusion. The low-temperature absorption spectrum observed clearly demonstrates that magnesium can pair with oxygen to form magnesium–oxygen complex impurities in silicon. Similar to an isolated magnesium donor, the magnesium–oxygen complex ...
