Answer: In the following equation, \(H_2O\) is considered as a binary compound.
Explanation: A binary compound is considered as a compound having 2 elements only. In the following chemical equation:
\(2Na+2H_2O\rightarrow 2NaOH+H_2\)
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: \(H_2O\) and \(NaOH\)
\(H_2O\) consists of 2 elements which are hydrogen and oxygen and hence is considered as a binary compound.
\(NaOH\) consists of 3 elements which are sodium, hydrogen and oxygen and hence, cannot be considered as a binary compound.
