Question

in the sandwiches mode, select the \cheese\ option and observe the equation given for the preparation of a cheese sandwich. in the equation, set the number of bread slices to \2\ and the number of cheese slices to \1\. you will see that the product formed by these three ingredients is one cheese sandwich. suppose you have 40 bread slices and 30 cheese slices. how many cheese sandwiches can you make? express your answer as an integer. view available hint(s) part b part c submit sandwiches go to the molecules mode by selecting the icon at the bottom. notice that there are three real reactions: the synthesis of water, the synthesis of ammonia, and the combustion of methane.

Explanation:

Step1: Determine bread - based limit

Each cheese sandwich needs 2 slices of bread. With 40 slices of bread, the number of sandwiches possible based on bread is $\frac{40}{2}=20$.

Step2: Determine cheese - based limit

Each cheese sandwich needs 1 slice of cheese. With 30 slices of cheese, the number of sandwiches possible based on cheese is $\frac{30}{1}=30$.

Step3: Find the limiting - ingredient

The limiting ingredient is the one that restricts the number of sandwiches made. Since we can only make 20 sandwiches with the available bread (and we have enough cheese for more sandwiches if we had more bread), the number of cheese sandwiches we can make is determined by the bread.

Answer:

20
