a)Zn +H2SO4--->ZnSO4 +H2
b) Ta có
n\(_{H2}=\frac{11,2}{22,4}=0,5\left(mol\right)\)
Theo pthh
n\(_{ZnSO4}=n_{H2}=0,5\left(mol\right)\)
m\(_{ZnSO4}=0,5.161=80,5\left(g\right)\)
Chúc bạn học tốt
\(PTHH:Zn+H2SO4\rightarrow ZnSO4+H2\)
\(m_{H2}=\text{ V/22,4 = 11,2/22,4 = 0.5 (mol)}\)
Theo PT
\(m_{H2}=m_{ZnSO4}\text{= 0,5 (mol)}\)
\(\Rightarrow m_{ZnSO4}=\text{n.M = 80,5 g}\)
