WebThe dynamics of bulk liquid para-cresol from 340–390 K was probed using a tandem quasielastic neutron scattering (QENS) and molecular dynamics (MD) approach, due to its relevance as a simple model component of lignin pyrolysis oil. QENS experiments observed both translational jump diffusion and isotropic rotation, with diffusion coefficients ranging … WebWrite an equation for the reaction and give the oxidation state of chlorine in the chlorine-containing species that is formed. 2Cl2 + 2H2O --> 4HCl + O2.
