In the following equation, is considered as a binary compound.

Explanation: A binary compound is considered as a compound having 2 elements only. In the following chemical equation:

There are 2 compounds present because compound is defined as the chemical combination of two or more elements in a fixed ratio.

In the equation, compounds are: and

consists of 2 elements which are hydrogen and oxygen and hence is considered as a binary compound.

consists of 3 elements which are sodium, hydrogen and oxygen and hence, cannot be considered as a binary compound.

if you mean hydrogen and oxygen then water is the product
