Amixture of n-hexane vapor and air leaves a solvent recovery unit and flows through a 70 cm diameter duct at a velocity of 3.00 m/s. at a sampling point in the duct the temperature is 40 c, the pressure is 850 mm hg, and the dew point of the sampled gas is 25 c. the gas is fed to a condenser in which it is cooled at constant pressure, condensing 60% of the hexane in the feed. a) perform a degree-of-freedom analysis to show that enough information is available to calculate the required condenser outlet temperature (c) and cooling rate (kw).b) perform the calculations to acquire the required condenser outlet temperature (c) and cooling rate (kw).

Covalent network solids typically have melting points and boiling points. the chemical formula of a network solid indicates in the molecule.

In saturated organic compounds, all the bonds between carbon atoms are called?

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
