解析 Yes, carbon dioxide (CO2) is indeed an acidic oxide. 二氧化碳 (CO2) 是一种酸性氧化物,因为它能与水反应生成碳酸 (H2CO3),一种弱酸。这个反应可以表示为:CO2 + H2O → H2CO3。这种性质使二氧化碳在许多化学反应中扮演重要角色,例如酸雨的形成和人体呼吸作用中调节血液 pH 值。
You can liquefy the carbon dioxide to separate it from the other constituents.(你可液化二氧化碳以使它与其他成分分离。) Dissolved carbon dioxide makes the water more acidic.(溶解的二氧化碳使水更具酸性。) Through this incision, the abdominal cavity is distended with carbon dioxide gas.(通过此切...

was∼4000 per Zn1.5cluster of Zn-DPA, and the turnover frequency (TOF) was∼2000 per Zn1.5cluster of Zn-DPAper hour. To the best of our knowledge, these values are higher than all of those previously reported for MOF-based catalysts in the cycloaddition of carbon dioxide to epoxides u...
Carbon dioxide (chemical symbol CO2) is a colorless, acidic gas with a density approximately 53% more than that of dry air CO2molecules are formed via a covalent double bond between a carbon atom and two oxygen atoms. It occurs naturally as a trace gas in the Earth’s atmosphere. Volcanoes...
2. Carbon dioxide capture, transport and storage 2.1. CO2 capture The first step of the CCS chain is the capture process. A major element of this process comprises the separation of CO2 from a gas stream. This can be the separation from produced natural gas, which of...

摘要: Due to interaction with carbon dioxide, when some adsorbed oxygen atoms on silver surfaces are converted into carbonate groups, the binding energy diminishes and the volatility of adsorbed oxygen rises.关键词: Molecular dynamics Langevin dynamics atomic trajectories time-dependent properties soft-...
Irrespective of the delivery method, the sulphur is absorbed to form calcium sulphite or sulphate. This material may be regenerated in a separate by-product process to recover SOx (usually as an acid) and recycle the absorbent or can be marketed as synthetic gypsum. Carbon dioxide has been ...
