Fe + H2SO4---> FeSO4 + H2
0,01------------------------------0,01(mol)
mFe=56.0,01=0,56(g)
%mFe=\(\frac{0,56}{1}\).100%=56%
%mCu=100%-56%=44%
nFe= 0,56(g)
PTHH : H2SO4+Fe--->FeSO4+H2
=>%mFe = 56%
=>%mCu= 100%-56%= 44%
a)Fe+H2SO4--->FeSO4 +H2
b) Ta có
n\(_{H2}=\)\(\frac{0,224}{22,4}=0,01\left(mol\right)\)
Theo pthh
n\(_{Fe}=n_{H2}=0,01\left(mol\right)\)
m\(_{Fe}=0,01.56=0,56\left(g\right)\)
%m\(_{Fe}=\frac{0,56}{1}.100\%=56\%\)
%m\(_{Cu}=100\%-56\%=44\%\)
