Limiting/excess...

I thought for a moment I had found a good website explaining limiting and excess but I was wrong. It starts off with explaining what limit and excess is. Great! It is sort of obvious though but it is good they explain it anyway, for those of us who don’t get it completely.

With a simple example used, it helps explain the whole concept of limiting and excess. Just in case, I might explain as well.

Limiting is the chemical, reactant, object that limits the amount of product made. Such as the trusted example from Nick, 2 frames, 5 wheels. The limiting here is the frames, as you can only make 2 bikes from two frames. 

Excess is the chemical, reactant, object that is left over once all the limiting is used. Again with the same example, the excess here is the wheels, as you will have one wheel left after 2 bikes are made.

The site starts off well enough, however it goes on with some examples of calculations for limiting/excess and I cannot make heads or tails from it. It is confusing and looks nothing like the way we do it. It confused me and I was complexly at a loss. At least the explanations of limiting and excess were clear and simple for me.
