\(n_{BaO}=\dfrac{229,5}{153}=1,5\left(mol\right)\)
\(n_{CO_2}=\dfrac{56}{22,4}=2,5\left(mol\right)\)
PTHH: BaO + H2O ---> Ba(OH)2
2,5---------------->2,5
Xét \(T=\dfrac{1,5}{2,5}=0,6\) => Tạo cả 2 muối
PTHH: Ba(OH)2 + CO2 ---> BaCO3↓ + H2O
1,5--------->1,5------->1,5
=> nCO2 (dư) = 2,5 - 1,5 = 1 (mol)
PTHH: BaCO3 + CO2 + H2O ---> Ba(HCO3)2
1<---------1
=> nBaCO3 = 1,5 - 1 = 0,5 (mol)
=> mkết tủa = mBaCO3 = 0,5.197 = 98,5 (g)
\(^nBaO\) = \(\dfrac{229,5}{153}\) = \(1,5\) \(\left(mol\right)\)
\(^nCO_2\) = \(\dfrac{56}{22,4}\) = \(2,5\) \(\left(mol\right)\)
\(PTHH\) : \(BaO+H_2O\) \(--->\) \(Ba\left(OH\right)_2\)

\(Xét\) \(T\) = \(\dfrac{1,5}{2,5}\) = \(0,6\) \(=>\) \(Tạo\) \(cả\) \(2\) \(muối\)
\(PTHH\) : \(Ba\left(OH\right)_2+CO_2--->BaCO_3\) ↓ \(+H_2O\)
\(1,5------->1,5--->1,5\)
\(=>^nCO2\left(dư\right)=2,5-1,5=1\left(mol\right)\)
\(PTHH:BaCO_3+CO_2+H_2O--->Ba\left(HCO_3\right)_2\)
