\(CuO+H_2\xrightarrow[]{t^o}Cu+H_2O\)
0,125->0,125
\(Fe_2O_3+3H_2\xrightarrow[]{t^o}2Fe+3H_2\)
0,25--->0,75
\(\Rightarrow V_{H_2}=\left(0,75+0,125\right).22,4=18,2\left(l\right)\)
\(m_{CuO}=\dfrac{50.20}{100}=10\left(g\right)\)
\(m_{Fe_2O_3}=50-10=40\left(g\right)\)
\(n_{CuO}=\dfrac{m}{M}=\dfrac{10}{80}=0,125\left(mol\right)\)
\(n_{Fe_2O_3}=\dfrac{m}{M}=\dfrac{40}{160}=0,25\left(mol\right)\)
\(CuO+H_2\underrightarrow{t^o}Cu+H_2O\)
\(1mol\) \(1mol\)
\(0,125mol\) \(0,125mol\)

\(1mol\) \(3mol\)
\(0,25mol\) \(0,75mol\)
\(V_{H_2}=n.22,4=\left(0,125+0,75\right).22,4=19,6\left(l\right)\)
