Liquid n-pentane and liquid n-octane are mixed to form a stream flowing at a rate of 1,496.5 lbm/hr. an in-line density measurement determines the mixture density is 0.654 g/ml. calculate the volumetric flow rate of the liquid n-pentane feed in cm3/sec. the specific gravities of n-pentane and n-octane are 0.631 and 0.708, respectively. assume ideal mixing.

What happens when an atom of sulfur combines with two atoms of chlorine to produce sci2? a. each chlorine atom shares a pair of electrons with the sulfur atom. b. an electron is transferred from each chlorine atom to the sulfur atom. c. an electron is transferred from the sulfur atom to each chlorine atom. d. each chlorine atom shares all its valence electrons with the sulfur atom.
