  2. O problema Benzenul(C6H6) reactioneaza cu clorul(Cl2) in prezenta FeCl3 formandu-se clorobenzensi acid clorhidric.Stiind ca reactioneaza a grame de clor , sa se determine masa de benzen(puritate 86%) care estenecesarapentru a se consuma tot clorul,sisa se determine cat la % din amestecul final este acid clorhidric.

  3. Analizaproblemei Pentru a rezolvaaceastaproblemaincepemprin a scriereactiachimicadintreceledouasubstante: + Cl2 -HCl

  4. Totul e simplu Am putearezolvaproblemaclasic cu pixulsihartiasafacem un numar mare de calculesauputemsa ne ajutam de calculator, care sa o rezolve . Asa ca pentru a economisitimp am propus un limbaj de programare(Pascal) care sarezolveaceastaproblemaintr-un timp de sub o secunda.

  5. Limbajul de programare vara,b,c,d,e,f,g,x,y,z,w,q:real; begin writeln('cantitatea (in grame) de clor care reactioneazaeste:');read(a); if a<>0 then begin writeln; writeln('C6H6+CL2=>C6H5Cl+HCl'); writeln; b:=12*6+6; c:=35.5*2; e:=12*6+5+35.5; f:=35.5+1; d:=a*b/c; g:=100*d/89; writeln('cantitatea de benzen este:',g:5:2); writeln; x:=f+e; y:=a*f/c; z:=a*e/c; w:=z+y; q:=100*y/w; writeln('procentul de acid clorhidric din amestecul final este:',q:5:2,'%'); end; readln; readln; end.
