### S-II - 2 e- → S0 (oxidation)

Na2S is an oxidizing agent, Na2S is a reducing agent.

### Word equation

sodium sulfide → sodium + mixed sulfur

### Input interpretation

Na2S → 2 Na + S

Sodium sulfide sodium mixed sulfur

### Balanced equation

Balance the chemical equation algebraically:

Na2S → 2 Na + S

Add stoichiometric coefficients, c, to the reactants and products:

c1 Na2S → c2 2Na + c3 S

Set the number of atoms in the reactants equal to the number of atoms in the products for Na and S:

Na: 2c1 = c2

S: c1=c3

Since the coefficients are relative quantities and underdetermined, choose a coefficient to set arbitrarily. To keep the coefficients small, the arbitrary value is ordinarily one. For instance, set c1 = 1 and solve the system of equations for the remaining coefficients:

C1 = 1 C2=2

C3 = 1

Substitute the coefficients into the chemical reaction to obtain the balanced

equation:

Na2S → 2 Na + S
