The chemical reaction represented by the following balanced chemical equation takes place in aqueous
solution: MnO4 + 5 Fe2+8H - Mn2 + 5 Fe3+ 4H2O
When the disappearance of the permanganate ion, MnO4, is monitored, the rate of reaction for the
consumption of the ion is 4.0x10^2 mol/L. s. Calculate the reaction rate for all other reactants and products.

Diffraction is when light is bent around obstructions. which of the these observation about clouds would indicate diffraction? a) after rain storms, you can sometimes see rainbows. b) clouds are white or gray and cannot be seen through. c) on a cloudy day, the temperature tends to be cooler than a sunny day. d) the edges of dark clouds appear lighter. this

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?
