Draw all resonance forms (neutral and charge separated) for cyclopropanone, cyclopentanone, cycloheptanone, cyclopropenone, cyclopentadienone, and cycloheptatrienone. Indicate the number of pi-electrons that are present in each ring and indicate whether or not a resonance form is aromatic.
If 508 nm is directly related to the d-orbital splitting Fe2+ o-phen complex, explain how this wavelength would change (become higher, lower, or stay the same) if we changed the reaction from using Fe2+ to Fe3+. Explain why the wavelength change o..
Calculate the mass of propylene glycolC3H8O2 that must be added to 0.320kg of water to reduce the vapor pressure by 2.88torr at 40C Pressure H2O 40C 55.3torr
what is the chemical equation that describes both these reactions? Please give the chemical equations of what happens in this situation
A testing facility found that 8.35*10^23 molecules of carbon dioxide were produced when a sample of octane was burned in air. If this combustion process is known to produce an 86.7% yield, how many grams of octane were in the sample?
For the reaction: H2SO4(aq) + 2 KOH(aq) --> K2SO4(aq) + 2 H2O To find the concentration of H2SO4, a 25.00 mL sample was titrated with 0.8752 M KOH. It took 31.79 mL of KOH to reach the endpoint of the reaction. What is the concentration of the H2S..
