Why does CH3-CH2-O-H have a higher boiling point than CH3-O-CH3 even though they have the same molar mass?
For a certain process at 27°C, DG = +210.6 kJ and DH = -168.2 kJ. What is the entropy change for this process at this temperature? Express your answer in the form, DS = ____ J/K.
a rod 8.6 cm long is uniformly charged and has a total charge of -26.1 muc determine the magnitude of the electric
What are the wavelengths, in nanometers, of the brightlines of the hydrogen emission spectrum
What is the equilibrium constant Kc of this reaction? Use an ICE table with numbers.
What is the relationship between K and Kc?
Some MF2 is dissolved in water at 25oC to make a saturated solution. (M is a mystery metal - it's identity can be ignored.) Some of the solution is removed and tested
Which compounds reacted only with AgNo3 in ethanol. Why. Did any compounds appear not to react under either condition, even when heat was added ? Explain, for each compound, why it might not react by a substitution reaction.
Electron affinity can be defined for molecules just as it is defined for single atoms. Write a complete chemical equation representing the electron affinity of OH. Include all relevant state symbols ((s), (g), etc.)
Dentists might use a mixture of 40% N2O and 60% O2 as an initial anesthetic of nitrous oxide(although exact proprtions may vary). Determine the entropy of mixing for 1 mole of such a mixture. Assume ideal gas conditions.
Draw the structure of the potential product if an elimination reaction takes place instead of substitution. NaBr + H2SO4 ---> HBr + NaHSO
Calculate the pH at the following points during the titration of 100.0 mL of 0.20 M acetic acid (Ka for acetic acid = 1.8 x 10-5) with 0.10M sodium hydroxide
