This makes it much more environmentally friendly and sustainable than electric light, which consumes a huge amount of non-renewable energy.(细菌提供的光是它们自然新陈代谢的一部分,所以产生光不需要能量,只需要生物体所需的能量。这使得它比消耗大量不可再生能源的电灯更加环保和可持续。)”可知,第三段...
Aliphatic or alicyclic C1 to C20 hydrocarbons are dehydrogenated in a process wherein the hydrogen produced is separated from the gaseous reaction mixture by contacting the reaction mixture with one side of a membrane selectively permeable to hydrogen, the unconverted reactants being further reacted...
A chemical reaction is one that causes chemical changes to the reacting substances, known as reactants. Bonds of the molecules making up the reactants are broken, allowing atoms to rearrange and create new bonds to form new molecules. Chemical reactions are usually not reversible....

这个题就比较简单了,很明显 E-己-1,3-二烯有共轭(离域)π键:the E-hexa1,3-diene has delocalised(conjugated) π bond, makes it more stable than two isolated πbond; so E-hexa-1,3-diene is less exothermic than E-1,4-diene, which has exactly twice hydrogenation enthalpy than hen-3-...
Redox Reaction Redox reaction involves the transfer of electrons from one chemical species to another.

They have also found a way to ensure that the reaction can be controlled precisely enough to supply only as much hydrogen as is needed at any given moment.28. Which of the following best explains “rugged” underlined in Paragraph 1? C A. Creative. B. Fragile. C.Tough. D.Enormous.29....
is unchanged, or a nuclear reaction, in which the composition of the atomic nucleus changes. In a chemical reaction, the atomic nucleus is untouched, but electrons may be transferred or shared to break and form chemical bonds. In both physical changes andchemical changes(reactions), the number...
By contrast, the precise control of the mesoporous structure in the matrix material, which directly correlates with mass diffusions and may play a dominant role in delivering industrially relevant reaction rates, has been overlooked. Here we report a general method for the synthesis of a single ...
