The volume of a quartz mineral sample was determined placing the weighed sample in a graduated cylinder containing 56.3 mL water. With the mineral sample completely submerged, the water level was 68.2 mL. THis measuring method, known as water displacement, uses the volume of an irregular object. The dry mass of the quartz sample was 31.18 g. What was the density of the quartz in g/cm^3?

What type of reaction is illustrated? 2c12o5 = 2cl2 + 502

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?
