A lesson that covers what a limiting reagent is, how to find the limiting reagent from masses (this is also found in the combined science specification), how to find the limiting reagent from the volume and concentration of solutions (separate chemistry) and how to find the limiting reagent from gas volumes (separate chemistry). This lesson is designed for the Edexcel 9-1 specification, separate chemistry and covers higher only content.

I think there is an issue with describing the limiting reagent as the one with the least moles as this only really applies if the ratio is 1:1. It should be the substance which completely reacts is limiting, and the one which is not all reacted is in excess.
excellent resource! can I ask - what is reason for slide 7, q5 you divided the H2 and made it 19/2 instead of keeping it 38/2 ? thanks
