1.) NaOH + HCl  →  NaCl  +  H₂O

2.) Ca(OH)₂  +  H₂SO4  →  CaSO₄ +  2H₂O

3.) 2HCl +Ba (OH)2  →  BaCl₂  +  2H₂O

4.) HNO3 + LiOH   →   LiNO₃  +  H₂O

5.) H₂CO₃ + NaOH  →  Na₂CO₃  +  H₂O

6.) KOH  +  HC₂H₃O₂  →  KC₂H₃O₂  +  H₂O

7.) Ba(OH)2 + HNO2  → Ba(NO₂)₂  +  H₂O

8.) H₂SO₃ + 2NaOH  →  Na₂SO₃  +  2H₂O

9.) H₃PO₄ + 3KOH  →   K₃PO₄  +   3H₂O 

10.) 2HBr + Ca(OH)2  →  CaBr₂  +  2H₂O

The reason why water is so recurrent is because of the general form that says:   ACID  +  BASE  →  SALT  +  WATER

I took the liberty of balancing the equations.

And a) oxygen i believe
