Half fill a set of four labeled small test tubes with 3 M H2SO4, 6 M HCl, 6 M CH3COOH, and 6 M H3PO4, in a test tube rack. Submerge a 1 cm strip of magnesium ribbon into each test tube. Compare the reaction rates and record your observations. 2. Different metals affect reaction rates.
WebDec 18, 2024 · MR16 used the "on-the-fly" weak reaction capabilities of MESA, as described and validated in Paxton et al. (2015, 2016). These capabilities calculate the weak reaction rates without recourse to tabulations using nuclear data drawn from the literature and numerically evaluating the phase space integrals at runtime each time a rate is needed.
