Which is the properly balanced equation for the process in which iron oxide (fe2o3) and carbon monoxide (co) react to produce iron (fe) and carbon dioxide (co2) gas?
a.
fe2o3 + co → fe + co2
b.
fe2o3 + 3co → 2fe + 3co2
c.
2fe2o3 + 3co → 2fe + 3co2
d.
3fe2o3 + co → 3fe + 2co2

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?
