in sour flavor in the sensory test. Different types of beers dosed with the same amount of acid measured the same TA, but they had different sourness levels in the sensory test. Also, beers dosed with double the amount of acid did not necessarily taste twice as sour, meaning that the ...
The lower the pKa value, the higher the Ka value of the compound, meaning it is a strong acid. Resonance stability can also affect the strength of an organic acid. When an acid is deprotonated, we form a negatively charged species called the conjugate base....
“There is a blank line [in the CQI and CSC tests] where students can write in their guess on acid, but it’s not part of the final grading,” he adds. “For me as an instructor, I find it is more important that students understand the underlying chemistry than grade their sensorial...
The activation parameters, solvent isotope effects, and excess acidity slope parameters mm* obtained in the analysis are tabulated and discussed. The parameters obtained for the parent styrenes 1 are very similar to those previously obtained for the phenylacetylenes YC6H4Ctriple bondCH, meaning that...
meaning that the likelihood of a compound event month would be twice as large as under independence. However, if only one out of 200 months was under MHW-OAX conditions, the LMF would be 0.5, meaning that the likelihood of a compound event month would be only half as large as under inde...
The chemical reactivity of a set of borophosphines of the general formula R2B-G-PY2, where G is the connector group between the Lewis acidic site, a borane

[31]; however, the deposition surrogate used in CMAQ was methylhydroxyperoxide, a slowly depositing molecule, which has a Henry’s law constant four orders of magnitude less than that of IEPOX, meaning that depositional loss of IEPOX to wet surfaces was most likely significantly underestimated ...
HMF yield declines from 44.8% to 24.3%. HMF yield does not show improvements when MIBK is used to extract HMF from water in a biphasic system. These results suggest the deactivation effect of water on UiO-66-NO2-25. HMF yield in DMF is 4.8%, meaning that DMF can deteriorate the cataly...
