Question

Asked Oct 25, 2019

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 36 slices of bread and 45 slices of cheese.

Which of the two ingredients limits the number of sandwiches that can be made?

slices of bread

slices of cheese

What quantity of the ingredient in excess remains?

slices

Step 1

Given:

Number of bread slices = 36 slices

Number of cheese slices = 45 slices

1 sandwich = 2 slices of bread + 3 slices of cheese

Step 2

Calculation for number of sandwiches based on bread slices:

Number of sandwiches = number of bread slices / 2

Number of sandwiches = 36/2 = 18 sandwiches.

Step 3

Calculation for number of sandwiches based on cheese slices:

Number of sandwiches = num...
