In a high-pressure separation process, a gas having amasscomposition of 50 wt% benzene, 30 wt % toluene, and 20 wt % xylene is fed into the process at the rate of 483 m3/hr at 607 k and 26.8 atm. one exit stream is a vapor containing 91.2 mole % benzene, 7.2 mole % toluene, and 1.6 mole % xylene. a second exit stream is a liquid containing 6.0wt % benzene, 9.0wt % toluene, and 85.0wt % xylene. what is the composition(mas fractions)of the third exit stream if it is liquid flowing at the rate of 9800 kg/hr, and the ratio of the benzene to the xylene in the stream is 3 kg benzene to 2 kg xylene?

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
