por la combustión de la fosfina se obtiene el pentóxido de difosforo según la siguiente reacción: 2PH3(g) + 4O2(g) P2O5 (s)+ 3H2O(l). Si combustionan 34g de fosfina . ¿Cuántos litros de oxígeno se consumen?

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?
