When sodium bicarbonate and acetic acid are combined in a beaker and allowed to run to completion, a small amount of sodium bicarbonate remains unreacted at the
bottom of the beaker at the end of the experiment. This means that the sodium
bicarbonate is the
in this experiment.

A) catalyst

B)product

C)excess reactant

D)limiting reactant

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?
