Question

Dau coroana. Urgent!!!!

Answer 1

niu,benzan= m/M= 3900g/78g/mol= 50mol

r1:  C6H6+ Cl2---> C6H5Cl +HCl                  ORI 15a

r2: C6H6+ 2Cl2--> ortoC6H4Cl2 + 2HCl    ori  2a

r3: C6H6 + 2Cl2---> para C6H4Cl2+2HCl   ori 3a

r4: C6H6------------------------> C6H6              ori 5a

                                                                  total 25mol

25a=50----> a=2mol

a)in r1 intra 30mol benzen si rezulta 30mol clorobenzen

=> m= niuxM=30molx112,5g/mol=..................calculeza!!!!

b) eta= niu benzen din r1x100/ niu benzen total= 30x100/50=................

c)30mol(r1)+8mol(r2)+12mol(r3)=50mol

V= niuxVm= 50x22,4 l=..........................calculeaza !!!!
