Using the following reactions: 2KMnO4 + 5KNO2 + 3H2SO4 > 2MnS4 + #H2O + 5KNO3 + K2SO4
KClO3 + C12 H22O11 ---> KCl + H2o + CO2
K2Cr2O7 + SnCl2 + HCl ---> CrCl3 + SnCl4 + KCl + H2O
Mg + HCl > Mg Cl2 + H2
Fe + V2O3 ---> Fe2O3 + VO
How many of the above reactions are oxidation -reduction reactions?

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?
