a) \(n_{C_2H_4}=\dfrac{4,958}{24,79}=0,2\left(mol\right)\)
PTHH: \(C_2H_4+3O_2\xrightarrow[]{t^o}2CO_2+2H_2O\)
0,2---->0,6---->0,4---->0,4
\(\Rightarrow V_{O_2}=0,6.24,79=14,874\left(l\right)\)
b) \(V_{CO_2}=0,4.22,4=9,916\left(l\right)\)
c) \(Ca\left(OH\right)_2+CO_2\rightarrow CaCO_3\downarrow+H_2O\)
0,4------>0,4
\(\Rightarrow\left\{{}\begin{matrix}x=m_{CaCO_3}=0,4.100=40\left(g\right)\\y=m_{b\text{ình}.t\text{ăng}}=m_{CO_2}+m_{H_2O}=0,4.44+0,4.18=24,8\left(g\right)\end{matrix}\right.\)
