\(n_{CO2}=\frac{2,24}{22,4}=0,1\left(mol\right)\\ n_{Ba\left(OH\right)_2}=\frac{10\%\cdot322}{171\cdot100\%}\approx0,18\left(mol\right)\)
Ta có :
\(T=\frac{n_{CO2}}{n_{Ba\left(OH\right)2}}=\frac{0,1}{0,18}\approx0,5\\ \Rightarrow0< T\le1\)
=> Tạo muối trung hòa, CO2 hết
PTHH:
\(CO_2+Ba\left(OH\right)_2\xrightarrow[]{}BaCO_3\downarrow+H_2O\)

Dung dịch sau phản ứng chứa ddBa(OH)2 dư
\(m_{ddspư}=0,1\cdot44+322-0,1\cdot197=306,7\left(g\right)\)
\(n_{Ba\left(OH\right)2dư}=0,18-0,1=0,8\left(mol\right)\)
\(C\%_{ddBa\left(OH\right)2}=\frac{0,8\cdot171}{306,7}\cdot100\%=44,6\%\)
