a)PTHH: Zn + H2SO4 -> ZnSO4 + H2
b) nH2 = 2,24/22,4= 0,1(mol)
nH2SO4= nZnSO4= nH2= 0,1(mol)
=> m(muối)= mZnSO4= 161.0,1= 16,1(mol)
c) mH2SO4= 0,1. 98= 9,8(g)
=> mddH2SO4= (9,8.100)/20= 49(g)
a)Zn+H2SO4--->ZnSO4+H2
b) n H2=2,24/22,4=0,1(mol)
Theo pthh
n ZnSO4=n H2=0,1(mol)
m ZnSO4=0,1..161=16,1(g)
c) Theo pthh
n H2SO4=n H2=0,1(mol)
m H2SO420%=\(\frac{0,1.98.100}{20}=49\left(g\right)\)
