Below are the half reactions for sulfate reduction using acetate as a source of electrons, energy, and carbon. CO2 + 8e- -> CH3COO- (-0.29 volts) SO42- + 8e- -> H2S (-0.22 volts) If you balance and combine the reactions so that 29 molecules of CH3COO- are oxidized to CO2, how many electrons are transferred from carbon to sulfur?

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?
