Answer 1

•KOH + HNO3 → H2O + KNO3

•2 NaOH + SO2 → H2O + Na2SO3

•2 NaOH + SO2 → H2O (l) + Na2SO3

•BaO + HBr → OH + BaBr

•Fe + CuSO4 → FeSO4 + Cu

•NaOH + HCl → H2O + NaCl

•2 KOH + H2SO4 → 2 H2O + K2SO4

•2 HF + CaO → CaF2 + H2O

•Zn (s) + FeSO4 (aq) → ZnSO4 (aq) + Fe

Answer 2

Sure, let's balance the given chemical equations one by one:

1. $KOH + HNO_3 = KNO_3 + H_2O$
2. $2NaOH + SO_2 = Na_2SO_3 + H_2O$
3. $2KCl + H_2SO_4 = K_2SO_4 + 2HCl$
4. $BaO + 2HBr = BaBr_2 + H_2O$
5. $Fe + CuSO_4 = FeSO_4 + Cu$
6. $2NaOH + H_2SO_4 = Na_2SO_4 + 2H_2O$
7. $2KOH + H2SO4 = K2SO4 + 2H2O$
8. $AgBr + AgNO_3 = 2Ag + HNO_3$
9. $CaO + 2HF = CaF_2 + H_2O$
10. $Zn + CuSO_4 = ZnSO_4 + Cu$

I have balanced the given chemical equations to the best of my knowledge. If you need further assistance, please feel free to ask.
