Question

The concept of determining which reactant is limiting and which is in excess is akin to determining the number of sandwiches that can be made from a set number of ingredients. Assuming that a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, determine the number of whole cheese sandwiches that can be prepared from 44 slices of bread and 69 slices of cheese.
_____ sandwiches

slices of cheese
slices of bread

    Answer:

    Slices of bread will limit the number of sandwiches that can be made.

    The quantity of ingredient in excess remains is 3 slices of cheese.

    Step-by-step explanation:

    The reagent that is present in less amount in the reaction mixture is called limiting reagent. It gets exhausted at the end of the reaction. Limiting reagent governs the formation of products.

    Given:

    2 slices of bread with 3 slices of cheese consists of 1 sandwich.

    It can also be written as:

    1 slice of bread with 3/2 slices of cheese consists of 1/2 sandwich.

    Or,

    1 slice of bread with 1.5 slices of cheese consists of 0.5 sandwich.

    44 slices of bread with 1.5*44 slices of cheese consists of 0.5*44 sandwich.

    So,

    44 slices of bread by using 66 slices of cheese, 22 sandwiches can be made.

    Since, we have 69 slices of cheese and we have to use only 66 slices of cheese. It is present in excess.

    So, slices of bread will limit the number of sandwiches that can be made.

    Also, the quantity of ingredient in excess remains is 3 (69-66) slices of cheese.
