What does it mean to say that there is some uncertainty in every measurement we make using a measuring device? How many significant figures is contained in the value 0.00000102584? a) 11 b) 6 c) 5 d) 4 e) 12 How many significant figures are contained in the value 1.0350? a) 5 b) ...
Even so, I am not persuaded to believe any of the proposed mechanisms for the quinoline dione example in Wikipedia. An SN2 displacement on a tertiary trifluoroaceate does not seem likely. Direct displacement by attack on the oxygen of the trifluoroacetate does not seem likely. Perhaps addition ...
What does this mean for applications of AI in drug discovery? AI can, in principle, deliver all of the above aims: it can make decisions faster (predictions are faster than experiments) and more cheaply (predictions cost less than experimen...
What does this mean? Use the equations with the enthalpy information given below to calculate the H for the reaction: S(s) + O2(g) --> SO2(g) S(s) + 3/2 O2(g) --> SO3(g) H = -395kJ 2 SO2(g) + O2(g) --> 2 SO3(g) H = How is the enthalpy of a system ...
What is the standard free energy change delta G rxn? Based on the value of Delta G What is entropy, and what is delta S for a reaction, and what does it mean if delta S is positive or negative? A chemical reaction has a -6.0 kJ/mol change in Enthalpy and a -9.0 J/K Entro...
What is the perfect definition of chemical in terms of general chemistry and organic chemistry? Explain what makes a good NMR solvent. Explain what the terms endo and exo mean with respect to the stereochemistry of the products formed in the Diels-Alder rxn using maleic ...
