a)C₅H₁₁OH + 5O₂ -> 5CO + 6H₂O
b)C₈H₁₇OH + 12O₂ -> 8CO₂ + 9H₂O
c)2C₅H₉(OH)₃ + 3O₂ -> 10C + 12H₂O

wzór ogólny kwasów - CnH2n+1COOH=108
12n +2n +1 +45=108
n=4
czyli to kwas pentanowy - C₄H₉COOH
60:10:32 - 6:1:3,2 -C:H:O
89.
wzór ogólny alkoholi: CnH2n+1OH, czyli:
C₉H₁₉OH
masa= 108 + 20 + 16 = 144g
CnH2n+1COOH=144
14n + 1 + 45= 144
n=7
czyli: C₇H₁₅COOH - kwas heptanowy
