\(Zn+2HCl--->ZnCl_2+H_2\) \((1)\)
\(Fe+2HCl---> FeCl_2+H_2\) \((2)\)
\(a)\)
\(mFe=\dfrac{60,5.46,289}{100}=28(g)\)
\(=> nFe=\dfrac{28}{56}=0,5(mol)\)
\(=> mZn=60,5-28=32,5(g)\)
\(=> nZn=\dfrac{32,5}{65}=0,5(mol)\)
\(b)\)
Theo PTHH (1) và (2) \(nH_2=0,5+0,5=1(mol)\)
\(=> VH_2(đktc)=1.22,4=22,4(l)\)
\(c)\)
Theo (1) \(nZnCl_2=nZn=0,5(mol)\)
\(=> mZnCl_2=0,5.136=68(g)\)
Theo (2) \(nFeCl_2=nFe=0,5(mol)\)
\(=> mFeCl_2=0,5.127=63,5(g)\)
