Calculate the diameter of a discrete particle whose terminal settling velocity is 1.044 x 10-2m/s. the particle density is 2.650 kg/m3 and the water temperature is 15°c. assume stokes' law applies and that the density of water is 1 000 kg/m3. nb: the dynamic viscosity of water at 15°c is 1.235 x 10-3 pa. s

The electron configuration for chromium is 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 3 d 5 4 s 1 instead of 1 s 2 2 s 2 2 p 6 3 s 2 3 p 6 3 d 4 4 s 1 . the configuration is an exception to the
