If one is given a set of ions then how do we judge their relative degrees of hydration ? (that is their relative hydration enthalpies)

I think one important factor is Charge/Mass ratio. Are there any other factors ?

I was doing some questions from organic chemistry and I came across a reagent :

" TsCl "

I want to know what this reagent does, and also what Ts stands for. Is it a organic group like Ph for Phenol? And also what is the specific use of this substance.

It is simplest to just put

It should be a planar wavefront.

It is becuase Change in Electric Field travels at the speed of light. Hence the Electric Field is generated instantaenously all throughout the metal conductor, and the current is set up All through the body of the conductor as soon as the potential difference is applied.

For Question 44

Considering that the loop is complete, we know that the electric field at the center will be zero. Now consider an element on the ring of length ∂l. The electric field exerted by this element at the loop center must be equal in magnitude and opposite in direction to the field exerted by the rest of the loop at the its center. So

E(at center due to the remaining wire) = E(at center due to ∂l)

The question is:

Consider a solid sphere of radius 'r' and mass 'm' which has a charge 'q' distributed uniformly over its volume. The sphere is rotated about a diameter with an angular speed 'ω'. Show that the magnetic moment 'μ', and the angular momentum 'l' of the sphere are related as :

μ = ql / 2m

I am unable to obtain the function that must be integrated in order to get the final expression. Please help.
