Question

Masa de acid acetic care intra in reactie si volumul de hidrogen degajat prin actiunea acidului acetic asupra a 0,1 moli fier.

Answer 1

Răspuns:

M,CH3COOH= 60g/mol

Vm= 22,4L/mol

2mol.................1mol.....................................1mol

2CH3-COOF + Fe----> (CH3COO)2Fe + H2

x.........................0,1mol.................................y

x= 0,2mol acid acetic

m=niuxM=0,2x60g= 12g acid acetic

y=0,1molH2

V=niuxVm= 0,1x22,4 l=2,24 l H2
