Write the reaction equation: benzene-nitrobenzene-aniline-carbon dioxide

Here are the records of the reaction equations:
C6H6 + HO – NO2 = C6H5 – NO2 + H2O – the nitration reaction occurs when heated in the presence of sulfuric acid as a dehydrating agent, nitrobenzene is released;
С6Н5NO2 + 6H = C6H5NH2 + 2Н2О – reduction of nitrobenzene with hydrogen, aniline is formed, N.N. Zinina.
С6Н5NH2 + О2 = СО2 + N2 + H2O – combustion of aniline, carbon dioxide is released.
These reactions show the properties of nitrogen-containing organic compounds. The reaction products are used in manufacturing, for example, aniline is the basis in the preparation of dyes.
