de Broglie wavelength.
(a). What is the kinetic energy of electrons whose de Broglie wavelength matches the size of a benzene ring? (280 pm)
(b). To give electrons this amount of energy, through what potential difference must they fall?
Radiation with a 58.4 nm of wavelength interacts with a H 2 (hydrogen atom)and induces the ejection of an electron then determine the kinetic energy of the departing electron express your answer in eV?
what mass of sucrose should be combined with 478 of water to make a solution with an osmotic pressure of 8.60 at 320 ?

sample of amygdalin yields alpha hydroxyphenylacetic acid that consists of 70% of the R isomer and 30% of its enantiomer. What is the specific rotation of this mixture? The specific roation of pure (R)-alpha-hydroxyphenylacetic is -154.
Calculate the pH of the solution made by adding 0.50 mol of propanoic acid, (C2H5COOH or HC3H5O2) and 0.30 mol of sodium propanoate (C2H5COONa or NaC3H5CO2) to 1.00 L of water. The value of Ka for C2H5COOH is 1.3 x 10^-5.
