Besides its use in making black-and-white film, silver nitrate (AgNO3) is used similarly in forensic science. The NaCl left behind in the sweat of a fingerprint is treated with AgNO3 solution to form AgCl. The precipitate is developed to show the black-and-white fingerprint pattern. Given ΔHlattice of AgNO3 = 822 kJ/mol and ΔHhydr = −799 kJ/mol, calculate its ΔHsoln.

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion. what is the frequency f of oscillation?
