a, \(CO_2+Ca\left(OH\right)_2\rightarrow CaCO_3\downarrow+H_2O\)
\(CO+CuO\rightarrow Cu+CO_2\uparrow\)
b, \(n_{Cu}=\frac{1,6}{64}=0,025\left(mol\right)\)
\(\rightarrow n_{CO}=n_{Cu}=0,025\left(mol\right)\)
Mà \(n_{CO,CO2}=\frac{1,12}{22,4}=0,05\left(mol\right)\)
\(\%_{CO}=\frac{0,025}{0,05}=50\%,\%_{CO2}=100\%-50\%=50\%\)
c, \(n_{CO2}=n_{CO,CO2}-n_{CO}=0,05-0,025=0,025\left(mol\right)\)
\(\rightarrow n_{CaCO3}=n_{CO2}=0,025\left(mol\right)\)
\(\rightarrow m_{CaCO3}=0,025.200=2,5\left(g\right)=m\)
