Can you give a specific example of a resonance structure and a similar related isomer? How are they similar?
What makes them different?
The cell potential of the following electrochemical cell depends on the ph of the solution in the anode half-cell:
is independent of pressure. By doing so, obtain an expression for V as a function of T and ? at fixed P.
calculate the number of excess reagent units remaining when 84 C2H4 molecules and 270 O2 molecules react?
A confiscated white substance suspected of being cocaine was purified by a forensic chemist and subjected to elemental analysis. Combustion of a 50.68 mg sample yielded 150.0 mg of CO2 and 46.05 mg of H2O. Analysis for nitrogen showed that the..
A certain first order reaction A->B while performed at 25 degree C is 25% complete after 42 min. Explain what is the rate constant of this reaction
What mass of precipitate will form if 1.5 L of excess Pb(ClO3)2 is mixed with .550 L of .270M NaI. Assume 100% yield and slight solubility of PbI2 Pb(ClO3)2 + 2NaI --> PbI2 (s) + 2NaClO3 (aq)
Splitting patterns and integrations may be used more than once, or not at all, as needed. Likewise, some bins might remain blank. Note that peak heights are arbitrary and do not indicate proton integrations.
In a 500 to 1000 word narrative, describe how the original vision of e-commerce did not work out for most e-tailers, but how the online retail marketplace is nevertheless the fastest growing channel in retail commerce.
calculate the equilibrium constant for the neutralization reaction. To calculate the equilibrium constant, you may find it helpful to represent the neutralization reaction as the sum of two separate reactions. (b) Calculate the pH, [CH3CH2NH2], and..
Calculate the molar concentration of the stock solution.
For restriction digestion, how would you dilute the 10X buffer so that it was at the correct concentration (1X) in the reaction solution
Why does the nitrogen atom of NH2 (and not the nitrogen atom of the NH) group of phenyl hydrazine act as the nucleophilic site in the format ion of the phenylhydrazones.
