Question

Write the correctly balanced equation in the following case:

When carbon dioxide is passed over red hot coke.

Answer 1

Balance equation:

• A balanced chemical equation has the same number of atoms on the reactant and product sides for each element involved in the reaction.
• When carbon dioxide(${\mathrm{CO}}_2$) is passed over red hot coke (carbon), then carbon monoxide($\mathrm{CO}$) forms.

The balanced equation is:

$$\begin{gathered} {\mathrm{CO}}_{2_{\left(\mathrm{g}\right)}}+{\mathrm{C}}_{\left(\mathrm{s}\right)}\stackrel{∆}{\to }2{\mathrm{CO}}_{\left(\mathrm{g}\right)} \\ \mathrm{Carbon}\mathrm{dioxide}\mathrm{Carbon}\mathrm{Carbon}\mathrm{monoxide} \end{gathered}$$
