Consider the solubilities of a particular solute at two different temperatures.
Temperature (°C) Solubility (g/100 gH2O)
20.0 44.0
30.0 80.9
1. Suppose a saturated solution of this solute was made using 60.0 gH 2 O at 20.0°C. How much more solute can be added if the temperature is increased to 30.0°C?

Can you me with this i really appreciate it

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?
