4. Calculate the concentrations of Ca2 and C2O4 2- in the first well without a precipitate. Note: In the well without a precipitate, all the Ca(NO3 )2 and the Na2C2O4 dissolved and disassociated. 5. Use the concentrations of Ca2 and C2O4 2- that you determined above to calculate the solubility product constant of CaC2O4. 6. Molecular motion increases with temperature. How does temperature affect the observed value of the solubility product constant

If a polyatomic ionic compound has gained two hydrogen ions, then how does its name begin?

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?
