以下哪种试剂不会影响以下转化？[img=232x51]18030582aa23711.gif[/img] A: KCl (5 molar solution) B: HCl & ZnCl2 C: SOCl2 D: PCl3

Going back to the earlier data set of human second molar breadth, calculate the following:What is the range (measured to 0.1 mmm)______ What is the standard deviation (measured to 0.1 mmm)______ What is the coefficient of variation (measured to 0.1)______

在温度为T 的抽空容器中，分别加入0.3 mol N2，0.1 mol O2及0.1 molAr，容器内总压力为101 325 kPa，则此时O2的分压力为________________。
