Question

1) K2O + H2SO3 → K2S03+Н20 2) ZnO + HCl→ 3) MgO + HCl → 4) BaO + H2SO4 → 5) Na2O + H2CO3 → 6) P2O5 + KOH → 7) P2O5 + NaOH →

Answer 1

2)ZnO+2HCl=ZnCl2+H2O
3)MgO+2HCl=MgCl2+H2O
4)BaO+H2SO4=BaSO4+H2O
5)Na2O+H2CO3=Na2CO3+H2O
6)P2O5+6KOH=2K3PO4+3H2O
7)P2O5+6NaOH=2Na3PO4+3H2O

Answer 2

Chemical Reactions

1) K2O + H2SO3 → K2SO3 + H2O - Potassium oxide reacts with sulfurous acid to produce potassium sulfite and water.

2) ZnO + HCl → - Zinc oxide reacts with hydrochloric acid to produce zinc chloride and water.

3) MgO + HCl → - Magnesium oxide reacts with hydrochloric acid to produce magnesium chloride and water.

4) BaO + H2SO4 → - Barium oxide reacts with sulfuric acid to produce barium sulfate.

5) Na2O + H2CO3 → - Sodium oxide reacts with carbonic acid to produce sodium carbonate.

6) P2O5 + KOH → - Phosphorus pentoxide reacts with potassium hydroxide to produce potassium phosphate.

7) P2O5 + NaOH → - Phosphorus pentoxide reacts with sodium hydroxide to produce sodium phosphate.
