conditions in x′, the domain satisfies L x′ sinθ ≃ 4h for θ > 0. (For θ = 0, we require L x′ & 6h.) Secondly, we greatly extend one of the dimensions, L z′, past the MFU requirement [Figure 3(c)], in practice between 30h and 220h, usually 120h. This approach presents two important advantages, one numerical and the other physical.

KOH(aq) + HCl(aq) → KCl(aq)+ H2O(l) The data below is from an experiment to determine the enthalpy change of this reaction. 50.0 cm3 of a 0.500 mol dm-3 solution of KOH was mixed rapidly in a glass beaker with 50.0 cm3 of a 0.500 mol dm-3 solution of HCl. Initial temperature of each solution = 19.6°C Final temperature of the mixture = 23.1°C
