a) Zn +2CH3COOH -> Zn(CH3COO)2 + H2↑
0,1 0,1 0,1
nZn= 6,5/65= 0,1 (mol)
b) VH2= 0,1 .22,4= 2,24 (l)
c) mZn(CH3COO)2= 0,1 . 183= 18,3 (g)
Đáp án:
Giải thích các bước giải:
nZn=6,5\65=0,1 mol
PT:
Zn+2CH3COOH-->Zn(CH3COO)2+H2
0,1---------------------->0,1---------->0,1 (mol)
=>VH2=0,1.22,4=2,24l
=>mZn(CH3COO)2=0,1. 183=18,3g
