Molecular models are great tools to help us understand limiting and excess reactants in chemistry.
Let’s think about making s'mores.
If you have:
the graham crackers are the limiting reactant.
This means you can only make 4 complete s'mores. You still have extra marshmallows and chocolate, but you can't make more s'mores without more graham crackers!
To make this idea clearer, you can use molecular models:
Create Molecules for Each Reactant: Use different colored balls to represent marshmallows, chocolates, and graham crackers.
Model the Reaction: Put the graham crackers together with matching marshmallows and chocolates.
When the graham crackers run out, the process stops, even if you have leftover marshmallows and chocolates.
This hands-on approach helps us see how limiting reactants affect what we can make, while the extra ones just sit around.
