Fe + 2HCl -- > FeCl2 + H2
nH2 = 0,896 : 22,4 = 0,04(mol)
=> nFe=nH2 = 0,04 (mol)
=> mFe = 0,04.56 = 2,24(g)
nFeCl2 = nH2 = 0,04(mol)
mFeCl2 = 0,04 . 127 =5,08(g)
\(n_{H_2}=\dfrac{0,896}{22,4}=0,04mol\)
\(Fe+2HCl\rightarrow FeCl_2+H_2\)
0,04 0,04 0,04 ( mol )
\(m_{Fe}=0,04.56=2,24g\)
\(m_{FeCl_2}=0,04.127=5,08g\)
PTHH: \(Fe+2HCl\rightarrow FeCl_2+H_2\)
\(n_{H_2}=\dfrac{V_{H_2\left(đktc\right)}}{22,4}=\dfrac{0,896}{22,4}=0,04\left(mol\right)\)
Theo PTHH: \(n_{Fe}=n_{H_2}=0,04\left(mol\right)\)
\(m_{Fe}=n.M=0,04.56=2,24\left(g\right)\)
Theo PTHH: \(n_{FeCl_2}=n_{Fe}=0,04\left(mol\right)\)
\(m_{FeCl_2}=n.M=0,04.127=5,08\left(g\right)\)
