Answer 1

Ответ:

KOH +HNO₃= KNO₃ +  H₂O

2NaOH + SO₂ = Na₂SO₃ +  H₂O

2KCl  +  H₂SO₄разб = реакция не идет

BaO  + 2HBr =  BaBr₂ +   H₂O

Fe+ CuSO₄ =  FeSO₄ +   Cu

NaOH + HCl  =NaCl  + H₂O

2KOH + H₂SO₄  = K₂SO₄  +2H₂O

AgBr+  HNO₃ =    AgNO₃ + H₂O

CaO + 2HF = CaF₂ +  H₂O

Zn    + FeSO₄    = ZnSO₄ +  Fe

Answer 2

Let's balance the chemical equations one by one:

1. KOH + HNO3 → KNO3 + H2O This is a neutralization reaction, forming potassium nitrate and water.

2. 2NaOH + SO2 → Na2SO3 + H2O This is a redox reaction where sodium hydroxide reacts with sulfur dioxide to form sodium sulfite and water.

3. 2KCl + H2SO4 → K2SO4 + 2HCl This is a double displacement reaction, forming potassium sulfate and hydrochloric acid.

4. BaO + 2HBr → BaBr2 + H2O This is also a double displacement reaction, producing barium bromide and water.

5. Fe + CuSO4 → FeSO4 + Cu This is a single displacement reaction, with iron displacing copper from copper sulfate to form iron sulfate and copper metal.

6. 2NaOH + H2SO4 → Na2SO4 + 2H2O This is another neutralization reaction, yielding sodium sulfate and water.

7. 2KOH + H2O2 → K2SO4 + 2H2O This reaction forms potassium sulfate and water, with hydrogen peroxide decomposing into water and oxygen.

8. AgBr + AgNO3 → 2Ag + HNO3 This reaction involves the formation of silver metal and nitric acid.

9. CaO + 2HF → CaF2 + H2O This reaction produces calcium fluoride and water.

10. Zn + H2SO4 → ZnSO4 + H2 This is a single displacement reaction, resulting in zinc sulfate and hydrogen gas.

Please note that these equations are balanced for mass and charge.
