The mass to use in the expression for the vibrational frequency of a diatomic molecule is the effective mass μ = mAmB/(mA + mB), where mA and mB are the masses of the individual atoms. The followingdata on the infrared absorption wavenumbers (wavenumbers in cm-1) of molecules are taken from Spectra of diatomic molecules, G. Herzberg, van Nostrand (1950):
H35Cl H81Br HI CO NO
2990 2650 2310 2170 1904
Calculate the force constants of the bonds and arrange them in order of increasing stiffness.
a) Using the value Ecell = 0.68V, calculate the [Ag+] in the test solution after equilibrium is reached. b). Setup a reaction table for equation above and calculate the formation constant for Ag(S2O3)23-.
The total volume of seawater is 1.5X10^21 L. Assume that seawater contains 3.1 percent sodium chloride by mass that its density 1s 1.03 g/mL. Calculate the total mass of sodium chloride.
What is the approximate value of the equilibrium constant, Kn, for the neutralization of hydrochloric acid with sodium hydroxide, shown in the equation below? HCL(aq) + NaOH(aq) --> H2O (l) + NaCl (aq)
The temperature of the acid solution increases from 24.2 oC to 29.9 oC. Calculate deltaH for the reaction that occurred.
Aerosol cans have a label that warns the user not to use them above a certain temperature and not to dispose of them by incineration. Even an empty can contains residual gaseous propellant.
