Write a balanced equation for the following chemical reactions: iii) Sodium + Water —-> Sodium hydroxide + Hydrogen

Answer:

A chemical equation represents a chemical process as a collection of substances. A balanced chemical equation has the same number of atoms on both sides of the equation.

(iii) 2Na(s) + 2H₂O (l) → 2NaOH (aq) + H₂ (g)

Sodium reacts with water to give sodium hydroxide and hydrogen gas. The reaction is an example of redox reaction.
