The answer is heterogeneous because if a salad is mixed by the following item it will not mix properly and we could easily separate them.

hope that helps you

have a great day!

Explanation:

A mixture in which solute particles are unevenly distributed into the solvent is known as a heterogeneous mixture.

For example, oil present in vinegar will unevenly mix together.

Whereas a mixture in which solute particles are evenly distributed into the solvent is known as a homogeneous mixture.

For example, salt dissolved in water is a homogeneous mixture.

Therefore, when a salad dressing is made by a chef  by mixing oil, vinegar, and spices then it is a heterogenous mixture.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
