Question

Write a balanced chemical equation for sodium to react with oxygen.

Answer 1

Balanced chemical reaction:

• A balanced chemical reaction is a reaction in which the number of atoms for every element in the reactant and the product side should have an equal number.
• Each atom in the reactant and the product side should be balanced using numbers.

Chemical Reaction of Sodium with Oxygen:

• Sodium belongs to alkali metals.
• It is a very reactive metal.
• It usually combines with oxygen to produce sodium peroxide as follows:

$2\mathrm{Na}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to {\mathrm{Na}}_2{\mathrm{O}}_2\left(\mathrm{s}\right)$
