Consider the equation. Which represents the correct mass-volume relationship at STP? 32.00 g of O2 react with an excess of H2 to produce (2 ´ 22.4) L of H2O. 2.00 g of H2 react with an excess of O2 to produce (2 ´ 22.4) L of H2O. 32.00 g of O2 react with an excess of H2 to produce 22.4 L of H2O. (2 ´ 2.00) g of H2 react with an excess of O2 to produce 22.4 L of H2O.

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?
