Question

HCL+K, K2O+SO3NaOH+P2O3серная кислота+оксид кальцияMg(OH)2+H2SO3Li2O+SO2HNO+BaSO3

Answer 1

2 HCl + 2 K → 2 KCl + H2

K2O + SO3 → K2SO4

6 NaOH + P2O3 → 3 H2O + 2 Na3PO3

CaO + H2SO4 → H2O + CaSO4

Mg(OH)2 + H2SO3 → 2 H2O + MgSO3

Li2O + SO2 → Li2SO3

2HNO3 + BaSO3 → BaSO4 + H2O + 2NO2

Answer 2

It seems like you've listed a series of chemical formulas and reactions. If you have specific questions about these chemical equations or if you're looking for information on the reactions involved, I'd be happy to help. However, it would be helpful if you could provide more context or specify what information you're seeking about these chemical compounds and reactions.
