This chapter explains the sensitization and inhibition of the hydrogen–oxygen reaction by additives and the role of NO in the explosive reaction of hydrogen and oxygen. The inhibiting effect of NO2 implies that NO2 undergoes a reaction, which destroys H atoms, and in this way counteracts the ...
The Reaction between Hydrogen and Oxygen BERNARD LEWIS Ph.D., Sc.D. (Cantab.), GUENTHER von ELBE Ph.D. (Berlin), in Combustion, Flames and Explosions of Gases (Second Edition), 1961 2 Sensitization and Inhibition of the Thermal Reaction by Additives The mechanism of the hydrogen-oxygen re...
The homogeneous reaction between hydrogen and oxygen is interesting if only because it is one of the most fundamental reactions from the purely chemical point of view, but it appears also to be specially worthy of further investigation because it is kinetically of so remarkable a nature. 展开 ...
题目In the reaction between hydrogen and oxygen to form water, hydrogen is ___. A. oxidized B. reduced C. unchanged D. decomposed 相关知识点: 试题来源: 解析 A。原因:文中提到 Hydrogen is oxidized as it loses electrons.反馈 收藏
WE have made a preliminary survey of the principal respects in which the reaction of deuterium with oxygen differs from that of ordinary hydrogen. The deuterium was prepared by the nearly quantitative decomposition of 97 per cent deuterium oxide by repeated passage over pure iron. The reaction ...
aIn others, such as the relatively slow solution of copper, in sodium chlo¬ride, the removal of hydrogen, which must occur so that corrosion may proceed, is effected by a reaction between hydrogen and some oxidizing chemical such as oxygen to form water. 在其他,例如铜的相对地缓慢的解答,...
In zinc corrosion in hydrochloric solutions, two cathodic reactions can happen: reduction of oxygen and hydrogen evolution reaction. These two processes take up electrons, making the entire zinc corrosion rate heightened as well. When a piece of steel is submerged in hydrochloric acid, strong bubble...
The reaction of water decomposing into hydrogen and oxygen by electrolysis is___. A. combination reaction B. decomposition reaction C. displacement reaction D. double displacement reaction 相关知识点: 试题来源: 解析 B。水电解分解成氢气和氧气,这是分解反应。一种物质分解成两种物质。反馈...
