Calculate the number of milliliters of 0.709 M KOH required to precipitate all of the Co2+ ions in 116 mL of 0.502 M Coso, solution as Co(OH)2. The equation for the reaction is:
CosO4(aq) + 2KOH(aq) —Co(OH)2(8) + K2SO4(aq)
mL KOH

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?
