At 300k and at a total pressure of 35.5 kpa, the composition of the system ethanol (1) and toluene (2) at equilibrium is x, = 0.35 and y, = 0.78.the saturation pressure at the given temperature for pure components are p = 45.05 kpa and p, = 10 kpa respectively. calculate the liquid phase activity coefficients and the value rt .) ; , = 1.55,7 =17 -0.413 b) 7 = 1.95,7 = 1 c) 7 = 1.25.7 d) 7, = 1.75

people flirt to show their affection towards someone in a less forward way then telling. they want the other person to guess what they’re feeling to have the other person also start to like them

120,630,890

step-by-step explanation:

110+10=120,620+10=630,880+10=890

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
