Question

Write a word equation for the following:

Carbon reacts with oxygen to form carbon dioxide.

Answer 1

• Carbon reacts with oxygen to form carbon dioxide.
• $\underset{\mathrm{carbon}}{\mathrm{C}\left(\mathrm{s}\right)}+\underset{\mathrm{oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}$
• This is an example of a combination reaction i.e. a reaction in which two or more than two substances combine to form a single substance.
