What is the mass of water in the final mixture? total = 185kg compos tion bwale 350-185 = 165hg 7. to measure the flowrate of an effluent stream, 5 kg/h of sodium chloride is added continuously to the stream, which initially has sodium chloride concentration of 0.002 wt%. downstream of the introduction point, a sample of the effluent stream shows 0.05 wt% sodium chloride. assuming steady state operation and that the added sodium chloride is well mixed with the effluen stream by the time the sample is taken, calculate the mass flow rate of the effluent stream in kg/h

answer; ///i do believe that the correct answer is (b); ///particle composed of two or more atoms bonded together;

  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-
