Question

Clasa 11... ajutati-ma va rog

Answer 1

---> CH3-CH2-CH2-CH3   BUTAN

----->CH3-CHCl-CH3        2 cloro propan

-----> CH3-CHBr-CH2Br    1,2 dibromo propan

---> --[C(CH3)H-C(CH3)H-]n-       poli2butena  

(aseaza cei doi CH3 sub cei 2 C)

P=95%

P=m,pX100/m,i---> m,p =700x95/100g= 665g

M,C5H10=70g/mol=====.> niu= 665g/70g/mol= 9,5 mol C5H10

1mol..............................5mol

C5H10 +15/2O2----> 5CO2 + 5H2O

9,5mol.........................niu= 9,5x5mol=47,5molCO2

m= niuxM= 47,5X44g=-.......................CALCULEAZA

V= niuxVm= 47,5x22,4 l=.......................calculeaza !!!!!
