Question

Hoàn thành các pt sau :

BaO --> Ba(OH)₂---> BaCO₃----> BaCl₂

Answer 1

BaO+H2O-----Ba(OH)2

Ba(OH)2+CO2---->BaCO3+H2O

BaCO3+2HCl---->BaCl2+H2O+CO2

Answer 2

\(BaO+H2O\rightarrow Ba\left(OH\right)2\)

\(\text{Ba(OH)2 + Ba(HCO3)2 → H2O + 2BaCO3}\)

\(\text{2HCl + BaCO3 → BaCl2 + H2O + CO2}\)
