What is the mass in grams of 1.73 moles cah2

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

Ineed this asap part i: scientific method what is the difference between science and pseudoscience? what is the scientific method?

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?
