Write down the reaction equations: calcium carbonate – calcium oxide – calcium carbide – acetylene – benzene

Write down the reaction equations: calcium carbonate – calcium oxide – calcium carbide – acetylene – benzene – nitrobenzene – aniline – tribromaniline

1) CaCO3 → CaO + CO2 (temperature; calcium oxide).
2) CaO + 3C → CaC2 + CO (calcium carbide, carbon monoxide (carbon monoxide (II)).
3) CaC2 + 2H2O → Ca (OH) 2 + C2H2 (calcium hydroxide, acetylene).
4) 3C2H2 → C6H6 (conventional: activated carbon, temperature 400-600 degrees Celsius) (benzene).
5) С6Н6 + HNO3 → С6H5NO2 + H2O (nitrobenzene).
6) С6H5NO2 + 3 (NH4) 2S → С6H5NH2 + 3S + 6NH3 + 2H2O (aniline, sulfur, ammonia).
7) С6H5NH2 + 3Br2 (aq. Solution) → С6H2NH2Br3 + 3HBr (tribromaniline, hydrogen bromide).
