Chapter U4.26, Problem 1TAI

Interpretation Introduction

Interpretation:The ingredient that willrun out of first is to be identified. The number of sandwiches that can be made is to be interpreted.

Concept introduction:The reagent in reaction that controls the amount of product formed is termed as limiting reagent. After completion of chemical reaction, the limiting reagent is fully utilized.

Answer to Problem 1TAI

The ingredient that will run out of first is bread. The number of sandwiches that can be made is twelve (12).

Explanation of Solution

The package of cheese contains 15 slices and the loaf of bread contains 24 slices. It is known that a cheese sandwich is made by one slice of cheese and two slices of bread. Since one slice of cheese makes one cheese sandwich. Therefore, 15 slices of cheese will make 15 cheese sandwiches. It is also known that one cheese sandwich requires 2 slices of bread. Therefore, 15 cheese sandwiches will require 30 slices of bread, only 24 slices of bread are present. Therefore, bread is the limiting reagent and will run out of first.

Since 2 slices of bread make one sandwich. Therefore, 24 slices of bread will make 12 breads.

Conclusion

Bread is the limiting reagent and fill run out of first. The number of sandwiches that can be made is twelve (12).
