First, lets look at the definition of post-medium. It is not 'after' medium as we might initially assume, but instead the breakdown of media. Traditionally we have 3 catagories of medium; drawing, paintin...

Flat 6-membered ring with 6 carbons. Each carbon in bonded two 1 hydrogen and 2 other carbons. Because a carbon must always have 4 bonds, there is a delocalised fourth electron on each carbon, which moves...

1. Identify that we are looking at dy/dx, not dx/dy and realise the relationship that dy/dx=1/(dx/dy)2)Try find dx/dy;cot = 1/tan or (tan)^-1Hence, x=(tan y )^-1 implying dx/dy = (-...

For efficient diffusion there must be a concentration gradient that is maintained, a large surface area to volume ration and a short distance for the gases to diffuse across. There are adaptations at the ...

To solve this problem we first must look into the given formula for time (T). It is stated, in the question, that the time taken is dependent on distance x. From this we can infer that the following probl...
