Question

Give word equation for nitrogen dioxide to nitric acid.

Answer 1

The nitrogen dioxide reacts with oxygen and water vapour of the air to give nitric acid.

Word equation:

$\mathrm{Nitrogen}\mathrm{dioxide}+\mathrm{Oxygen}+\mathrm{Water}\mathrm{vapour}\to \mathrm{Nitric}\mathrm{acid}$

Chemical equation:

$$\begin{gathered} 4{\mathrm{NO}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)+2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{g}\right)\to 4{\mathrm{HNO}}_3\left(\mathrm{l}\right) \\ \mathrm{Nitrogen}\mathrm{dioxide}\mathrm{Oxygen}\mathrm{Water}\mathrm{vapour}\mathrm{Nitric}\mathrm{acid} \end{gathered}$$
