How many liters of 1.5 m hcl solution would react completely with 6.5 moles ca(oh)2? ca(oh)2(s) + 2 hcl(aq) yields cacl2(aq) + 2 h2o(l) 2.2 l hcl(aq) 4.9 l hcl(aq) 8.7 l hcl(aq) 1.9 l hcl(aq)

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?
