a) PHHH: Zn + H2SO4 -> ZnSO4 + H2
nH2=1,5(mol)
=>nZn=nH2=1,5(mol)
b) mZn= 1,5.65= 97,5(g)
=> mCu=200-97,5=102,5(g)
a) PTHH: \(Zn+H_2SO_4\rightarrow ZnSO_4+H_2\uparrow\)
b) Ta có: \(n_{H_2}=\dfrac{33,6}{22,4}=1,5\left(mol\right)=n_{Zn}\)
\(\Rightarrow m_{Zn}=1,5\cdot65=97,5\left(g\right)\) \(\Rightarrow m_{Cu}=102,5\left(g\right)\)
