Asked by Callie

Which chemical equation shows that no atoms are lost during a chemical reaction?
A. 8Fe+s8-->Fe5
B. 8Fe+8S8--> 8FeS
C. Fe+8S8--->FeS
D. 8Fe+S8--->8FeS
Is the answer A?
Answered by Brady
As for much chemistry, I don't know much. However, I will try, like the other one.

Well, it seems to want which one is an "balanced" chemical reaction. On looking up examples, and how to do them, it seems to me like algebra.

With A, there seems to be an error with the right side. The right side needs to have a S with the Fe. For that reason, I believe A is incorrect.

With B, "8S8" just tells me that is incorrect. Plus, there would be a bigger number on the right side as well, because of it.

For C, there would have to be a number on the right side.

For D, 8FeS is also 8(Fe + S). Do the distributive property, and you get what is on the left side of: 8Fe + S8

I hope this helps?!? :)
