Limiting Reagents
If you have worked out the MOLES of two reactants then the limiting reagent is the one with less moles. Sorted? Well, it depends. If the reactants are in a 1:1 ratio then the above is true. But if the ratio is not equal then I'm afraid it's a bit more complicated. Let's say reactants A and B have a ratio of 2:1 in the balanced equation. If we have 0.020 moles of A and 0.015 moles of B which is the limiting reagent? If we start with A we can see from the ratio that 0.02 moles
