Zn+2HCl->ZnCl2+H2
0,05--0,1
nZn=3,25\65=0,05 mol
=>VHCl=0,1\0,5=0,2 mol
Zn+2HCl->ZnCl2+H2
0,05--0,1
nZn=3,25\65=0,05 mol
=>VHCl=0,1\0,5=0,2 l
a, PTHH: Zn + 2HCl ----> ZnCl2 + H2 (1)
b, nZn = 3,25/65 = 0,05 (mol)
Theo (1) : nHCl = 2.nZn = 2. 0,05 = 0,1 (mol)
\(V=\frac{n}{C_M}=\frac{0,1}{0,5}=0,2\left(l\right)\)
