Question

Give balanced equation for the action of water on the following :

Sodium oxide

Answer 1

Balanced chemical equation :

• The method of representing chemical reactions in terms of symbols and the formula of the substance involved in it is called a chemical equation.
• The chemical equation in which the number of atoms of each element is equal to both sides of the arrow.

The action of sodium oxide with water:

• Sodium oxide reacts with water to form a basic alkali hydroxide called sodium hydroxide.
• Sodium oxide + Water $\to$ Sodium hydroxide
• $$\begin{gathered} {\mathrm{Na}}_2\mathrm{O}\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to 2\mathrm{NaOH}\left(\mathrm{aq}\right) \\ \mathrm{Sodium}\mathrm{water}\mathrm{Sodium} \\ \mathrm{oxide}\mathrm{hydroxide} \end{gathered}$$
• $$\begin{gathered} \mathrm{Elements}\mathrm{Reactant}\mathrm{side}\mathrm{Product}\mathrm{side} \\ \mathrm{Na}22 \\ \mathrm{O}22 \\ \mathrm{H}22 \end{gathered}$$

Hence, the equation has equal numbers of atoms on both sides, it is a well-balanced equation.
