The cell potential for the cell Zn(s) + 2H+(? M) LaTeX: \longrightarrow⟶ Zn2+(1.3 M) + H2(g) (8 atm) is observed to be 0.68 V. What is the pH in the H+/H2 half-cell? Reduction potential for H2(g)/H+(aq) is 0.00 V, for Zn(s)/Zn2+(aq) is -0.76 V. Enter number to 2 decimal places.

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?
