Răspuns:
1) glicerina C3) este solubila in apa poate forma leg de hidrogen
propena (C3) nu este solubila in apa
2) C4H9-OH =C4H8+ H2O
3 ) M butanol=74
74Kg but................22,4m3 C4H8
29,6.Kg........................X
X=29,6x22,4/74=8,96m3
4) C6H5-COOH +KOH=C6H5COOK+H2O
5) Macid=122
MKOH=56
122g..............................56g KOH
48, 8g...........................X
X=48,8x56/122=22,4g
1000ml...........................0,1x56gKOH
X......................................22,4g
X=22,4x1000/5,6=4000ml=4l
