I first want you to tell me why having a homogenous sample is good but also why it is bad. That is, what are the advantages and disadvantages to having a homogenous sample

Following are the responses to the given question:

Explanation:

In many analyses, the homogenous sample with only a particular identity group is desired. Units were picked here depending on their similar characteristics so because research is specifically interested in these qualities. The downside of a homogeneous sample is nevertheless that the exterior validity of a study is decreased. In other words, any results obtained could be appropriately widespread to the general population. On either hand, a heterogeneous sample is capable of overcoming this difficulty, because its diversity is the typical pattern of any sort of sample distortion inside the broader population.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
