Question

Write the skeletal equation for the following word equation:

Sodium + Water $\to$Sodium hydroxide + Hydrogen

Answer 1

• A skeletal equation is in the form of the equation in which the formula of the reactants is written on the left-hand side and that of the products on the right-hand side.
• The direction of the reaction is shown with an arrow ($\to$) between the reactants and products. Such equations are not balanced.
• Given equation: Sodium + Water $\to$Sodium hydroxide + Hydrogen
• The skeletal form of the equation will be: $\underset{\mathrm{Sodium}}{\mathrm{Na}\left(\mathrm{s}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}\to \underset{\mathrm{Sodium}\mathrm{hydroxide}}{\mathrm{NaOH}\left(\mathrm{aq}\right)}+\underset{\mathrm{Hydrogen}}{{\mathrm{H}}_2\left(\mathrm{g}\right)}$
