a) Calculate teh energy absorbed in (kJ/mol) by a carbon dioxdie molecule that has absorbed a single photon of Thermal IR light having wavelength of 15 micrometers.
b) What fraction of the energy required to dissociate CO2 does the value you got in part "a" correspond to? Note: the enthalphy of dissociation of a single atom of Oxygen from CO2 is 532 kJ/mol
Determine the molarity of the NaOH(sodium hydroxide) solution. In an acid-base titration, 22.13 mL of a sodium hydroxide solution are required to neutralize 24.65 mL of the potassium hydrogen phthalate solution?
General Chemistry: Energy, Volume, Mass, Molarity, and Moles, Benzene is an organic solvent with the formula C6H6. It boils at 80.1 degrees celcius and melts at 5.5 degrees Celsius. Benzene's density is 0.88gm/ml; its heat of vaporization is 30.0 ..
Explain why a buffer made of equal concentrations of CH3COOH and CH3COO- does not change in pH when a small amount of NaOH (a strong base) is added to the solution. Does the NaOH dissociate into ions when it is added to the solution?
