discharges of "mountain artillery" on humbler principles; attributing them to the loud reports made by the disruption and fall of great masses of rock, reverberated and prolonged by the echoes; others, to the disengagement of hydrogen, produced by subterraneous beds of coal in a state of ...
Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal matter.[9][note 1] Stars such as the Sun are mainly composed of hydrogen in the plasma state. Most of the hydrogen on Earth exists in molecular forms such as water and organic compounds...

However, repeated attempts byDavyto detect the presence of oxygen in chlorine and hydrogen chloride finally lead him to conclude in 1810 that, on the basis of Lavoisier's own operational definition, chlorine was an element. 然而,戴维多次尝试检测氯和氯化氢中是否存在氧,最终使他在 1810 年得出结论...
PROBLEM TO BE SOLVED: To provide a method for measuring the concentration of an organic matter in a mixed gas for containing the organic matter, hydrogen chloride, and phosgene that are extremely advantageous from the point of view of safety and operability.吉井 政之...
In STEC the research has also focused on this matter. Natarajan et al. [154] studied the RuO2 catalyst for OER reaction, evaluating the influence of the calcination temperature on the pre-treatment of the catalyst and obtaining the best behavior at a calcination temperature of 500 °C. At ...
In practice, alternative cathodic processes to hydrogen evolution may be available due to the presence of specific contaminants in the acid, in particular oxidants such as dissolved oxygen and metal cations in a higher oxidation state such as ferric, Fe3+or cupric, Cu2+ions. The presence of th...
