a,
- P1:
\(CO_2+Ca\left(OH\right)_2\rightarrow CaCO_3+H_2O\)
\(n_{CO2}=n_{CaCO3}=\frac{50}{100}=0,05\left(mol\right)\)
- P2:
\(CuO+CO\rightarrow CO_2+Cu\)
\(n_{CaCO3}=\frac{125}{100}=1,25\left(mol\right)\)
\(\Sigma n_{CO2}=1,25\left(mol\right)\)
\(\Rightarrow n_{CO}=n_{CO2}=1,25-0,5=0,75\left(mol\right)\)
\(\%V_{CO}=\frac{0,75.100}{0,75+0,5}=60\%\)
\(\%V_{CO2}=100\%-60\%=40\%\)
b,\(\%m_{CO}=\frac{0,75.28.100}{0,75.28+0,5.44}=48,84\%\)
\(\%m_{CO2}=100\%-48,84=51,16\%\)
