nZn= 0.5 mol
Zn + H2SO4 --> ZnSO4 + H2
Từ PTHH:
=> nH2= 0.5 mol
VH2= 11.2l
nH2SO4= 0.5 mol
VH2SO4= 0.5/2=0.25l
a) PTHH: Zn + H2SO4 \(\rightarrow\) ZnSO4 + H2\(\uparrow\)
b) nZn = \(\frac{3,25}{65}=0,05\left(mol\right)\)
Theo PT: n\(H_2\) = nZn = 0,05 (mol)
=> V\(H_2\) = 0,05.22,4 = 1,12(l)
c) Theo PT: n\(H_2SO_4\) = nZn = 0,05 (mol)
=> V\(H_2SO_4\) = \(\frac{0,05}{2}\)= 0,025 (l) = 25ml
