Kevin Hidalgo : Everyday Stoichiometry

Kim looks in the refrigerator and finds that she has 8 slices of ham. In order to make as many sandwiches as possible, how many pickles does she need? Use the following equation. 2H+C+T+5P+2B→H2CTP5B2

20 P

I don't like pickles. What would my ideal ham sandwich be?

2H+C+T+2B→H2CTB2

The ham sandwich is composed of 2 slices of ham (H), a slice of cheese (C), a slice of tomato (T) and 2 slices of bread (B). How to form the equation?

2H+C+T+2B→H2CTB2

Use the balanced "ham sandwich" equation from the concept, repeated below. 2H+C+T+5P+2B→H2CTP5B2 If you have 12 slices of ham, 4 slices of cheese, 5 tomato slices, 15 pickles, and 10 slices of bread, how many sandwiches can you make?

Use the balanced "ham sandwich" equation from the concept, repeated below. 2H+C+T+5P+2B→H2CTP5B2 You have 14 slices of ham. How many pickles are needed to make sandwiches with all of the ham?

35

Use the balanced "ham sandwich" equation from the concept, repeated below. 2H+C+T+5P+2B→H2CTP5B2 How many slices of cheese are required to make as many sandwiches from 16 slices of bread?

2H+C+T+2B→−−−− ?

H2CTB2

How does that change the equation?

It removes the pickles from the equation.

Will this change affect the amounts of other materials?

No, since only pickles is being removed and nothing else.

Define "Stoichiometry"

The calculation of amounts of substances in a chemical reaction from the balanced equation.

Use the balanced "ham sandwich" equation from the concept, repeated below. 2H+C+T+5P+2B→H2CTP5B2 You have 12 slices of ham, 4 slices of cheese, 5 tomato slices, 15 pickles, and 10 slices of bread. The reactant which determines the maximum amount of product that can be formed is called the limiting reactant. what is the limiting reactant?
