Answer:

I^{-}

K^{+}

Explanation:

As iodine has a higher electronegativity value and 7 valence electrons, it takes the valence electron of potassium to complete 8 electrons in its valence shell thus forming the anion I^{-} and, as consequence of losing one electron, the K atoms forms the cation K^{+}

The formula of potassium iodide is KI

B. Transport water and food.

Explanation:

The vascular tissue is known to be conducting tissue which has more than one cell type. It is usually found in vascular plants. It is composed of xylem and phloem.

Their function is to transport fluid (like water) and other nutrients, therefore they have cells that connect to form pipes. The xylem and phloem occur together in vascular bundles in the plant organs passing through stems, leaves and roots.

A mixture of compounds containing diethylamine, phenol, ammonia, and acetic acid is separated using liquid-liquid extraction as
umka2103 [35]

Answer:

I would expect to extract the acetic acid.

Explanation:

In the first step, since we are adding a concentrated acid,<u> it will react with the bases present in the mixture (diethylamine and ammonia) </u><u>forming salts</u><u>, </u><u>which are soluble in water</u>. Therefore, after draining the aqueous layer, we will have phenol and acetic acid left in the organic layer.

In the second step, we are adding a diluted base, so it will react with a strong acid. This compound is acetic acid, and its salt will be present in the aqueous layer. Phenol will be left on the organic layer.
