During the centuries following the collapse of the western Roman Empire, marble (calcium carbonate, CaCO3) was taken from the mon-
uments of Rome and heated to form quicklime (calcium oxide, Cao),
which was used to make plaster. Carbon dioxide, CO2, was also pro-
duced in this decomposition reaction. Write the balanced equation for
this reaction.

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?
