Question

帮帮忙。。。

Answer 1

1. NaOH + HCl == NaCl + H2O

2. NaOH + CH3COOH == CH3COONa + H2O

3. 2NaOH + H2SO4 == Na2SO4 + 2H2O

4. 6NaOH + 2H3PO4 == 2Na3PO4 + 6H2O

5. NaOH + H2CO3 == NaHCO3 + H2O

6. 2NaOH + H2CO3 == Na2CO3 + 2H2O

7. 2NaOH + CO2 == Na₂CO₃ + H₂O

8. 2NaOH + 2CO2 == 2NaHCO3

9. 2NaOH + SO2 == Na2SO3 + H₂O

10. NaOH + SO2 == NaHSO3

11. 2NaOH + SiO₂ = Na₂SiO₃ + H₂O

(3)

1. CL2+2NaOH==NaCl+NaClO+H2O

2. 3Cl2+6NaOH =△=5NaCl+NaClO3+3H2O

3. 3S + 6NaOH=△= 2 Na2S + Na2SO3 + 3 H2O

4. Si + 2NaOH + H2O == Na2SiO3 + 2H2↑
