14. Each beaker shown to the right contains iron and an acid. In which beaker will the iron dissolve the fastest
and why?
a. Beaker A because of a higher concentration level.
b. Beaker A because of increased surface area.
C. Beaker B because of a higher concentration level.
d. Beaker B because of increased surface area.

The question is incomplete, the complete question is attached in the image below:

The correct option is D) Beaker B because of the increased surface area.

Explanation:

A solution consists of solute and solvent.

A solute is defined as a component that is present in a smaller proportion while a solvent is defined as a component that is present in a larger proportion.

Solubility is defined as the amount of solute that can be dissolved in a given amount of solvent to form a solution.

Solubility of a substance depends on a few factors:

For the given images,

Beaker A has a large block of iron rod and Beaker B has iron shards.

The smaller molecular size of a substance increases its surface area and thus, increases the solubility.

Hence, the correct option is D) Beaker B because of the increased surface area.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
