Draw the skeletal structure, where each atom obeys the octet/duet rule and no atom possesses a formal charge, for the molecule whose condensed structure is:
a) (CH3)3CCH2CHC(CH3)2
b) (CH3)3CC(CH3)2CHCHCH3
In an experiment, 5.00 L of N2 is saturated with water vapor at 22°C and then compressed to half its volume at constant T. (a) What is the partial pressure of H2O in the compressed gas mixture?
Assuming that its molar heat of vaporization is constant at 28.4 kJ/mol, the boiling point of C2H5NH2 when the external pressure is 0.709 atm is K.
100 mL of 0.150 M acid H2A are mixed with 100 mL of 0.1600 M NaOH. Calculate the [H+] of the resulting solution at equilibrium. Ka1 = 1.0 x 10^-5 Ka2 = 1.0 x 10^-7
What is the pH during the titration of 25.00mL of 0.10M NH3 (Kb = 1.8 x 10-5) after the addition of 10.00mL of 0.10M HCl titrant?
Use the data given to calculate an overall energy change (in kilojoules per mole) for the formation of CsF2 from its elements.
Solutions of hexane and heptane may be considered to be ideal. At 25°C, the vapor pressure of pure hexane is 20.3 kPa and the vapor pressure of pure heptane is 6.08 kPa The activity relative to a pure liquid standard state is defined as the ratio ..
