\(n_{HCl}=0.5\cdot2=1\left(mol\right)\)
\(2Al+6HCl\rightarrow2AlCl_3+3H_2\)
\(..........1.........\dfrac{1}{3}.......0.5\)
\(V_{H_2}=0.5\cdot22.4=11.2\left(l\right)\)
\(m_{AlCl_3}=\dfrac{1}{3}\cdot133.5=44.5\left(g\right)\)
\(CuO+H_2\underrightarrow{^{t^0}}Cu+H_2O\)
\(0.5.....0.5\)
\(m_{CuO}=0.5\cdot80=40\left(g\right)\)
