-ecuatia reactiei de obtinere a acetilenei
1mol 1mol
CaC2 + H2O---> C2H2+CaO
(4OgCa+2x12gC)..... 22,4 dm³(l)
m=...................................8,96
m=25,6g carbid pur
-p/100= m,pur/m,i---> p=25,6x100/ 30= 85%
- ecuatia reactieie de bromurare
1mol 2mol
C2H2 + 2Br2---------> C2H2Br4
22,4 l............2molx2x80g/mol
8,96......................m= 128g Br2; este masa dizolvata in solutie---> m,d
- c/100= m,d/m,s---> 2/100= 128/ ms---CALCULEAZA m,s in grame!!!
