One of the things I learned in this unit is the importance of understanding the different types of reactions that can occur in a chemical reactor, such as exothermic and endothermic reactions. I also learned about the different factors that can affect the rate of a chemical reaction, such as...

A third reaction to time famine has been the growth of the work-life debate. You hear more about people taking early retirement or giving up high pressure jobs in favour of occupations with shorter working hours. And bodies such as Britain's National Work-Life Forum have sprung up, urging ...
Since the speed of light is well known, any delay in receiving the satellite's signal can be converted into a distance. 卫星从高空经过时发出能被汽车上计算机里的接收器辨认的无线电信号。汽车上的计算机就会根据信号传来所花的时间计算出卫星有多远。由于光速为人熟知,接收卫星信号时的任何时间迟缓都能...
过硫酸钾 0.3 苯乙烯 25 肥皂片 5.0 十二烷基硫醇 0.5 水 180 This mixture is heated with stirring and at 50℃ gives conversions of 5%~6% per hour. Polymerization is terminated at 70%~75% conversion by addition of a “short-stop”, such as hydroquinone (approximately 0.1 part), to ...
Therefore the temperature will decrease with radial position , i.e.,with the distance from the centerline of the pipe . 因此沿径向 方向也就是说随离管道中心线距离的增大, 温度降低。 Then , since the reaction rate increases with temperature , it will be higher at the center ,where the ...
