SO3+KOH--> Co2+Ca(OH)2--> N2O5+LiOH---> P2O5+Ba(OH)2-->

Question

SO3+KOH-->
Co2+Ca(OH)2-->
N2O5+LiOH--->
P2O5+Ba(OH)2-->

Answer 1

1)SO3+2KOH=K2SO4+H2O
SO3+KOH=KHSO4+H2O

2)CO2+Ca(OH)2=CaCO3+H2O
2CO2+Ca(OH)2=Ca(HCO3)2
CO2+2Ca(OH)2=(CaOH)2CO3+H2O

3)N2O5+2LiOH=2LiNO3+H2O

4)P2O5+3Ba(OH)2=Ba3(PO4)2+3H2O
P2O5+2Ba(OH)2=2BaHPO4+H2O
