Limiting Reactants & Limiting Reagents [ENDORSED]

[CenCen]

so, i was really confused in after having gone to my lecture and discussion. i just want to know if there's a difference between the two. If so, what is it?

[Samantha Geere]

There is a subtle difference. A reactant is a directly reacting substance present at the initiation of the reaction whereas a reagent is a substance participating in a chemical reaction. While all reactants are considered reagents not all reagents are considered reactants (ex: solvents and catalysts).

I have made one educational chemistry video about the limiting reactant calculation. Thank you very much. -Aya Ghoneum

Excellent and well organized video!

You did a great job explaining not only how to do a limiting reagent problem, but also when to do this calculation. Your video was very well done and organized. Awesome explanation.

I second that Aya!

How accurate should we be when rounding off atomic weights for elements in doing conversions from grams to moles? Should we generally truncate after 2 decimal points, or is it a matter of significant figures, or some combination?

Pretty sure it's typically a matter of sig figs given in the question.
