What is the calculated value of the cell potential at 298 k for an electrochemical cell with the following reaction, when the h; pressure is 3.77x10 bar, the h concentration is 1.49 m. and concentration is 5.57x104 m7 the cr l(g)+2cr '(aq) 61'(aq) 2cr(s) v answer the cell reaction as writen above is product-favored (spontaneous) for the concentrations given:

Is a pencil falling to the floor anon contact force, a force, or a contact force

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?
