Rezolvarea completa va rog! Multumesc anticipat!

Answer 1

a)

256 g .. V L

 CH4  +  Cl2 -->  CH3Cl  + HCl

 16............ 22,4

=> V = 256x22,4/16 = 358,4 L Cl2 la randament 100% , insa noi avem randament (eta) n = 90%

=> n = Cpx100/Ct => Vp = Vtxn/100

=> Vp = 358,4x90/100 = 322,56 L Cl2

b)

256 g ..................... m g ........ md g

 CH4  +  Cl2 -->  CH3Cl  + HCl

 16............................ 50,5........ 36,5

=> m = 256x50,9/16 = 808 g CH3Cl la randament 100% , insa noi avem randament (eta) n = 90%

=> n = Cpx100/Ct => Cp = Ctxn/100

=> Cp = 808x90/100 = 727,2 g CH3Cl

c)

md = 256x36,5/16 = 584 g HCl la randament 100% , insa noi avem randament (eta) n = 90%

=> n = Cpx100/Ct => Cp = Ctxn/100

=> Cp = 584x90/100 = 525,6 g HCl

d)

ms = md + m.apa = 525,6 + 200 = 725,6 g sol HCl

stim ca c% = mdx100/ms

=> c% = 525,6x100/725,6 = 72,44%
