Which of the following is a homogeneous mixture? tap water
chicken noodle soup
soil and water
applesauce

Water and applesauce are examples of a Homogeneous Mixture

Chicken Noodle Soup and Soil with Water would be examples of a Heterogeneous Mixture.

Explanation:

Homogeneous Mixtures are mixtures that are the same throughout, i.e. it's just one substance. A good example of this is a glass of water, this is because it is all one solution without any other visible different parts that will settle if left alone for a while. The same applies to the applesauce, it is one type of a mixture with nothing else added to it.

Hetergeneous Mixtures on the other hand are different substances added together. The noodles, soup and chicken, three different substances in one mixture. The soil and water mixture also applies, two substances which separate if left alone.

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.

the correct answer is:

a. formation of precipitation
