Question

Iron and sulfur react to yield iron sulfide. Balance this reaction.

___Fe(s) + ___S8(s) → ___FeS(s)

Answer 1

Answer:

8Fe + S8 -> 8FeS

Explanation:

Answer 2

Answer:

$8Fe_{(s)}+S_8_{(s)}\rightarrow 8FeS_{(s)}$

Explanation:

The unbalanced reaction of the reaction of Iron and sulfur is shown below as:-

$Fe_{(s)}+S_8_{(s)}\rightarrow FeS_{(s)}$

On the left hand side,  

There is 1 iron atom and 8 sulfur atoms.

On the right hand side,  

There is 1 iron atom and 1 sulfur atom.

Thus,  

Right side, $FeS$ must be multiplied by 8 to balance the sulfur and,

Left side, $Fe$ is multiplied by 8 so to balance the whole reaction.

Thus, the balanced reaction is:-

$8Fe_{(s)}+S_8_{(s)}\rightarrow 8FeS_{(s)}$
