It takes 6.86 kg of ethylene glycol (antifreeze; molar mass = 62.07 g/mol) to decrease the freezing point of 6.50 kg of water to -25 oF (-31.7 oC). How much sucrose (C12H22O11) would it take to decrease the freezing point of 6.50 kg of water to -25?

How would you reduce the volume of gas

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?

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
