PTHH: Zn+2HCl--->ZnCl2+H2
nZn= \(\dfrac{13}{65}=0,2\) mol
Theo pt: nZnCl2= nH2= nZn= 0,2 mol
=> mZnCl2= 0,2.136= 27,2 (g)
VH2= 0,2.22,4= 4,48 (l)
nZn = 13/65= 0.2 (mol)
Zn +2HCl -> ZnCl2 + H2
0.2 ----> 0.4 -----> 0.2 ----> 0.2
=> mZnCl2 = 0,2 . 136 = 27,2 (g)
V H2 = 0,2 . 22,4 = 4,48 (l)
nZn=13/65=0,2
Zn+2HCl--->ZnCl2+H2
0,2_________0,2____0,2
mZnCl2=0,2.136=27,2(g)
VH2=0,2.22,4=4,48(l)
