4Na + O2 + 2Na20.
Which statement best describes the reaction?
A. Elements rearrange, but no compounds are created or destroyed.
B.
OC.
Sodium oxide is created by the chemical reaction.
Atoms from sodium oxide rearrange to form sodium and oxygen.
In a mixture of the three substances, sodium oxide separates from the sodium and oxygen.
D.
What is the answer

C

Explanation:

This is a synthesis or a combination reaction , which involves the oxygen combining with sodium to make one compound.

hope it helps.

you're welcome.

h let me think

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.
