Using the van der Waal constants for methane in table 1.3 (a=2.283, b=0.04278) to calculate the initial slopes of the plots of the compressibility factor
if the molarity of the HCl solution was actually greater then the lable indicated would it affect the calculated value for the number of moles of HCl that reacted.
What are bonding theories? Why are they important? What may they be used for. HI has a force contents of 314 Nm^-1 and a bond length of 160.92 pm.
Converting between Units of Pressure Gases are different from solids and liquids. In a sample of gas, the molecules are far apart. The gas molecules also move around and collide with each other as well as with the walls of the container. These col..
