Question

DAU COROANA!!!VA ROG!!!

Answer 1

Răspuns:

Formula alcoolului este CnH2n+1OH

26,66/100=16/M

M=16×100/26,66=60g/mol

12n+n+1+16+1=60/-2,-16

14n=42--->n=3---->C3H7OH

m C3H7OH=d×V=400×0,8=320 g C3H7OH

nr moli alcool=m/M=320/60=5,333 moli

C3H7OH =H2O+C3H6 (în prezenta de H2SO4)

nr moli C3H7OH=nr moli C3H6----->nr moli C3H6=5,333 moli---->V=nr moli×V molar=5,333×22,4=119,46 L C3H6---->A)
