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 75 slices of cheese.

Answer:SLICE OF BREADStep-by-step explanation:If a cheese sandwich consists of 2 slices of bread and 3 slices of cheese, in order to determine the number of whole cheese sandwiches that can be prepared from 44 slices of bread and 69 slices of cheese, we will use the equality postulate as shown;1 cheese sandwich = 2 slices of breadx cheese sandwiches = 44 slices of breadcross multiply 2 * x = 1 * 442x = 44divide both sides by 22x/2 = 44/2x = 22Similarly;1 cheese sandwich = 3 slices of cheesey cheese sandwiches =  69 slices of cheesecross multiply 3 * y = 1 * 693y = 69 divide both sides by 33y/3 = 69/33y = 23Since both values of x and y are greater than or equal to 22 hence 22 sandwiches can be prepared from 44 slices of bread and 69 slices of cheese. Since the amount of cheese sandwiches made from slices of bread (22) is not up to that made from slices of cheese (i.e 23), hence the ingredient that limits the number of sandwiches that can be made is the slice of bread
