The answer for this stems from the very definition of what a transition metal is: a metal that can form one or more stable ions with partially filled d-subshell. The partially fill d-subshell part is cruc...

At first thought, the difference between form and structure can seem very fine, and it may be that at times they overlap, but there is certainly a difference. Form is concerned with ideas of genre that su...

Sure. If you remember how to calculate d/dx(uv) then you can understand how integration by parts works. d/dx(uv) = u(dv/dx) + v(du/dx). we can re-arrange this: u(dv/dx) = d/dx(uv) - v(du/dx). Now integrat...

First we have to identify that implicit differentiation is used to solve this question. We can differentiate the first the LHS first, by using the chain rule, we know that the differentiation of e^(xy) is...
