\(n_{H2}=\dfrac{2,24}{22,4}=0,1\left(mol\right)\)
a) Pt : \(Fe+2HCl\rightarrow FeCl_2+H_2|\)
1 2 1 1
0,1 0,1
b) \(n_{Fe}=\dfrac{0,1.1}{1}=0,1\left(mol\right)\)
\(m_{Fe}=0,1.56=5,6\left(g\right)\)
\(m_{Cu}=10-5,6=6,4\left(g\right)\)
0/0Fe = \(\dfrac{5,6.100}{10}=56\)0/0
0/0Cu = \(\dfrac{6,4.100}{10}=64\)0/0
