  We formulate hydrodynamic equations for nonsuperfluid multicomponent
magnetized charged relativistic mixtures, taking into account chemical
reactions as well as viscosity, diffusion, thermodiffusion, and thermal
conductivity effects. The resulting equations have a rather simple form and can
be readily applied, e.g., for studying magnetothermal evolution of neutron
stars. We also establish a link between our formalism and the results known in
the literature, and express the phenomenological diffusion coefficients through
momentum transfer rates which are calculated from microscopic theory.
