An ideal gas mixture is exerting 800 mmHg. I have measured the partial pressure of oxygen gas in the mixture to be 230 mmHg and the partial pressure of hydrogen gas in the mixture to be 310 mmHg. If the only other gas in the mixture is
nitrogen gas, then the partial pressure of nitrogen gas in the mixture is
mmHg.

Which of these would be caused by a chemical change? a) the formation of lava. b) sedimantary rock layering over time. c) metamorphic rock forming from igneous. d) metamorphic rock eroding to form sedimentary rock.

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?
