Question

Can someone help me figure this out? I have no idea where to start:

To make a smore, 2 graham crackers, a piece of chocolate, and a marshmallow are needed. You have 5 graham crackers, 7 pieces of chocolate and 5 marshmallows. Using smores as your example, explain the concepts of
limiting reactant
excess reactant
theoretical yield

Answer 1

I dont know how to do this. but there is info on google how to set it up.

Answer 2

Limiting Reactant - The reactant in a chemical reaction that limits the amount of product that can be formed.

Excess Reactant - The reactant in a chemical reaction that remains when a reaction stops when the limiting reactant is completely consumed.

Theoretical Yield is the quantity of a product obtained from the complete conversion of the limiting reactant in a chemical reaction.

Answer 3

In your smore what do you think will be your limiting reactant.

What is the ingredient that is going to finish sooner? limiting reactant
How many smore can you make with that ingredients? theoretical yield
What ingredients you will have as left over? excess reactant

Answer 4

i really don't know which one would be the limiting reactant but the product that would finish the soonest I'm guessing is the graham crackers.

Answer 5

right?
