Which statement describes where oxidation and reduction half-reactions occur in an operating electrochemical cell? (1) oxidation and reduction both occur at the anode
(2) oxidation and reduction both occur at the cathode
(3) oxidation occurs at the anode and reduction occurs at the cathode
(4) oxidation occurs at the cathode and reduction occurs at the anode

When curium-242 is bombarded with an alpha particle, two products are formed, one of which is a nudge on. what is the other product

Ineed to find the answer of this question because i dont understand it

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?
