Explosions using chemicals are accompanied by the release of hot gases, often seen by a shock wave traveling at speeds reaching 10300 m/s. Detonation of trinitrotoluene (TNT, C7H5N3O6) causes it to decompose and form the following gases: N2, H2, CO, and C. Write a balanced equation for the detonation of TNT.
Write the balanced reaction based on the molecules of a reaction shown below

Balance the equations below by adding the correct coefficients
— CuO + — CO → — Cu + — CO2
— Na3N + — H2O → — NaOH + — NH3
— SeO2 + — O2 → — SeO3
