IV. C6H6 + 3Cl2 => C6H6Cl6 (lindan)
2. ro=m/V=>m=ro*V=0,88*5000=4400g C6H6
78g C6H6.................................291g C6H6Cl6
4400g C6H6.............................x=16415,384g
13/100*16415,384=2134g lindan
3. 78g C6H6..................3*22,4L Cl2
4400g C6H6...................x=3790,769L Cl2
120/100*3790,769=4548,923L Cl2
V. 1. HC≡CH + HCl ⇒ CH₂=CHCl
nCH₂-CHCl ----> [CH₂-CHCl]n
2. Mpolimer = n*Monomer => n=Mpolimer/Mmonomer=50000/62,5=800
3. n(eta)=mp/mt*100 => mp=n*mt/100=90*7/100=6,3t
Imi spui daca am gresit ceva..
