Question

Equations that contain an equal number of atoms of each element on the two sides of the arrow head are called ___________ (skeleton/ balanced).

Answer 1

Balanced chemical equation:

• A balanced equation is a chemical equation that has an equal number of atoms of each element on both sides of the equation.

For example:

• The balanced equation for the decomposition of potassium chlorate is:

$$\begin{gathered} 2{\mathrm{KClO}}_{3\left(\mathrm{s}\right)}\stackrel{∆}{\to }2{\mathrm{KCl}}_{\left(\mathrm{s}\right)}+3{\mathrm{O}}_{2\left(\mathrm{g}\right)} \\ \mathrm{Potassium}\mathrm{Potassium}\mathrm{Oxygen} \\ \mathrm{chlorate}\mathrm{chloride} \end{gathered}$$

Therefore, equations that contain an equal number of atoms of each element on the two sides of the arrow head are called balanced Chemical equation
