For an equimolar solution of n-pentane and n-hexane, compute: a) The dew-point pressure at 1450F b) The bubble-point temperature at 2.3 bar c) The vapor fraction, at 145.F and 0.75 atm, and the mole fractions of the vapor and liquid phases d) Report the critical temperature, pressure and find the MSDS of both chemicals

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

there are two significant figures.

i think it's letter a.
