Question

What is the reducing agent in the following reaction? (PLEASE RESPOND FAST)

2Na + S --> Na2S
A. Na
B. S
C. Na2S
D. Na+ ​

Answer 1

S is the reducing agent in this rxn

Answer 2

A) Na

Step-by-step explanation:

We analyze the change of electrons in the equation.

So:

S (0) --> S (-2)

The oxidizing agent is the one that gains electrons. Sulfur goes from 0 to -2 then it is gaining electrons.

Na (0) --> Na (+1)

The reducing agent is the one that loses electrons. Sodium goes from 0 to +1 which means that it loses electrons.

Therefore the reducing agent is Na.
