The chromate and manganate esters shown below form from the
reaction of 3-butene-2-ol with chromic acid and manganese dioxide
(MnO2) respectively. They both decompose to give methyl
vinyl ketone through mechanistically distinct pathways. (a) Provide
the mechanism of the manganate ester decomposition and (b) indicate
which intermediate in your mechanism rationalizes the observation
that only allylic and benzylic alcohols react...

Draw the NaOH-mediated saponification reaction of a triacylglycerol in which you represent the hydrocarbon tails of the three acyl chains as R1, R2 and R3, i.e. as C-O-CO-R1 C-O-CO-R2 C-O-CO-R3. • Be sure to include OH' as a reactant, but do not include Nat. • Draw the reaction for the complexe saponification of the triacylglycerol. . You must include the...
(1) Given the following information: hydrocyanic acid HCN Ka = 4.0×10-10 diethylamine (C2H5)2NH Kb = 6.9×10-4 (1) Write the net ionic equation for the reaction that occurs when equal volumes of 0.152 M aqueous hydrocyanic acid and diethylamine are mixed. It is not necessary to include states such as (aq) or (s). (2) At equilibrium will the reactants or products...
We saw in Section 4.6 (Equation 4.20) that A′ = –nk BT ln Z. We will see in the next chapter that ∂A′/∂T=−S′. Perform the differentiation of A′ with respect to temperature and obtain the relationship for the entropy of an isolated system in terms of its partiton function Z.

A sphere of radius 0.500 m, temperature 25.5°C, and emissivity 0.819 is isolated in an environment of temperature 77.0°C. (a) At what rate does the sphere emit thermal radiation? (b) At what rate does the sphere absorb thermal radiation? (c) What is the sphere's net rate of energy exchange?
A metal smith pours 2.1 kg of lead shot at 94.2°C into 1.3 kg of water at 24.3°C in an isolated container. What is the final temperature of the mixture? Give your answer to one decimal place Cwater-4.19 kJ/(kg"K), Clead -0.129 kJ/(kg K)
16 Electric field ranking Three isolated pairs of charges are separated by the same distance in the three situations illustrated below. Rank the magnitudes of the electric fields at the midpoints (labeled P) from smallest to largest. Explain your answers. +2C +1C +2C +2C Case A Case B +2C
is not a reason why Clostridium dificile is an increasing concern in healthcare 41) Which of the following settings? - A) the endospores are naturally resistant to drugs and disinfectants B) antibiotic misuse and overuse C) antibiotic resistance D additional modes of transmission have occurred in several isolated ca E) emerging super strains
In a newly isolated strain of fruit flies with semi-sterility, two previously linked loci show a new linkage relationship. This could be due to the fact that the new strain is a. Homozygous for an inversion b. Heterzygous for an inversion c. Homozygous for a reciprocal translocation d. heterzygous for a reciprocal translocation e. Homozygous for a duplication
