This passage describes a chemical reaction. Read the passage. Then, answer the question below.
One of the oldest known fabric dyes is a substance called indigo (C16H10N202). For
many centuries, people extracted indigo from plants. Starting in the 1800s, indigo
could be made in factories using a new method called the Baeyer-Drewson process.
In the Baeyer-Drewson process, indigo and acetic acid (C2H4O2) form when
nitrobenzaldehyde (C2H5NO3), acetone (C3H60), and water (H20) are combined.
Today, the most common use for indigo is dyeing cotton for blue jeans.
In the chemical reaction described in the passage, which of the following are reactants?
Select all that apply.
acetone (C3H60)
nitrobenzaldehyde (C7H5NO3)
water (H20)
acetic acid (C2H4O2)

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.
