In this paper we aim at describing the hydrodynamic limit of a mixture of chemically reacting gases. Starting from kinetic Boltzmann-type equations, we derive Grad's 13-moments equations for single species. Then, after scaling such equations in terms of a suitable Knudsen number, we apply an asymptotic Chapman-Enskog procedure in order to build up hydrodynamic equations of Navier-Stokes type.
