PLEASE CAN YOU HELP ME I AM SO STUCK 17 POINTS In the titration the student used 25.0 cm3 of sodium hydroxide.

This volume reacted with exactly 20.0 cm3 of 0.1 mol/dm3 sulfuric acid solution.

The equation for the reaction is:

2NaOH + H2SO4 → Na2SO4 + 2H2O

What is the concentration in mol/dm3 of the sodium hydroxide solution?

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?
