The substances sodium (na), oxygen (o2), and sodium oxide (na2o) participate in this chemical reaction: 4na + o2 → 2na2o. which statement best describes the reaction? a. elements rearrange, but no compounds are created or destroyed. b. sodium oxide is created by the chemical reaction. c. atoms from sodium oxide rearrange to form sodium and oxygen. d. in a mixture of the three substances, sodium oxide separates from the sodium and oxygen.

The correct answer is Option B

Sodium oxide is created by the chemical reaction.

Reason: This is a covalent reaction in which the ions pair to form Na2O.

Both Na has a valency of +1 and O has two pair of free electrons. Oxygen shares its electron with Na to form Covalent compound Na2O.

It is an unstable compound and soon react with hydrogen to form sodium hydroxide
