Aliquid mixture containing 30 mole% propane, 40 mole% n-butane and 30 mole% isobutene is stored in a rigid container with a maximum allowable working pressure of 200 psig. the head space above the liquid contains only the vapors of the 3 hydrocarbons. what is the maximum temperature (in f) that the container must be stored to remain safe? assume pressure is equal to 540 mmhg.

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

  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-
