\(n_{C_2H_4}=\dfrac{4.48}{22.4}=0.2\left(mol\right)\)
\(C_2H_4+3O_2\underrightarrow{^{t^0}}2CO_2+2H_2O\)
\(0.2.........0.6........0.4..........0.4\)
\(V_{O_2}=0.6\cdot22.4=13.44\left(l\right)\)
\(m_{H_2O}=0.4\cdot18=7.2\left(g\right)\)
\(Ca\left(OH\right)_2+CO_2\rightarrow CaCO_3+H_2O\)
\(..............0.4.....0.4\)
\(m_{CaCO_3}=0.4\cdot100=40\left(g\right)\)
