Zn + 2HCl -> ZnCl2 + H2
nZn=1(mol)
Theo PTHH ta có:
nZn=nZnCl2=nH2=1(mol)
2nZn=nHCl=2(mol)
mZnCl2=136.1=136(g)
mH2=2.1=2(g)
mHCl=36,5.2=73(g)
Zn + 2HCl \(\rightarrow\) ZnCl2 + H2
nZn=1(mol)
Theo PTHH ta có:
nZn=nZnCl2=nH2=1( mol)
nHCl=2.nZn=2(mol)
mZnCl2 = 136.1=136(g)
mH2=2.1=2(g)
mHCl = 36,5.2=73(g)
