11. 12) A potassium hydroxide (KOH) solution has a molar concentration of 0.026 M. Calculate the [H3O+], [OH-] and pH of the solution. Remember that Kw= 1.0 x 10-14M2 o TH0+1= 3.8x10-13. TOH1=2.6x10-2M, pH=12.42

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?
