常见化学反应方程式

一、非金属单质(F2,Cl2,O2,S,N2,P,C,Si)

1、氧化性:

F2 H2 = 2HF

F2 Xe(过量) = XeF2

2F2 (过量) Xe = XeF4

nF2 2M = 2MFn (M表示大部分金属)

2F2 2H2O = 4HF O2

2F2 2NaOH = 2NaF OF2 H2O

F2 2NaCl = 2NaF Cl2

F2 2NaBr = 2NaF Br2

7F2(过量) I2 = 2IF7

Cl2 H2 = 2HCl

3Cl2 2P = 2PCl3

Cl2 PCl3 = PCl5

Cl2 2Na = 2NaCl

3Cl2 2Fe = 2FeCl3

Cl2 2FeCl2 = 2FeCl3

Cl2 Cu = CuCl2

2Cl2 2NaBr = 2NaCl Br2
