\(n_{CO2}=\dfrac{6,72}{22,4}=0,3\left(mol\right)\)
\(n_{Ca\left(OH\right)2}=\dfrac{14,8}{74}=0,2\left(mol\right)\)
Ta có : \(0,5< \dfrac{0,2}{0,3}< 1\)
Vậy sản phẩm là hai muối: CaCO3 và Ca(HCO3)2
PTHH: \(Ca\left(OH\right)_2+CO_2\Rightarrow CaCO_3+H_2O\)
pư............x...................x.................x.............x (mol)
PTHH: \(Ca\left(OH\right)_2+2CO_2\Rightarrow Ca\left(HCO_3\right)_2\)
pư............y...................2y.....................y (mol)
Ta có: \(\left\{{}\begin{matrix}n_{CO2}=0,3\left(mol\right)\\n_{Ca\left(OH\right)_2}=0,2\left(mol\right)\end{matrix}\right.\Rightarrow\left\{{}\begin{matrix}x+2y=0,3\\x+y=0,2\end{matrix}\right.\)
Giải hệ \(\Rightarrow\left\{{}\begin{matrix}x=0,1\\y=0,1\end{matrix}\right.\)
\(\Rightarrow\left\{{}\begin{matrix}m_{CaCO3}=100.0,1=10\left(g\right)\\m_{Ca\left(HCO3\right)_2}=162.0,1=16,2\left(g\right)\end{matrix}\right.\)
Vậy.........
