In the Sandwiches mode, select the "Cheese sandwich" option and observe the equation given for the preparation of a cheese sandwich. When the number of bread slices and cheese slices is set to "0," you will see that there is "no reaction." Now, 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 elements is one cheese sandwich with two slices of bread and one slice of cheese. This equation can be written as

1. B

2. C

3. B

4. C

5. No limiting ingredient

6. C

7. No limiting ingredient

8. B

Explanation:

There is some info missing. I think this is the complete question.

In the Sandwiches mode, select the "Cheese sandwich" option and observe the equation given for the preparation of a cheese sandwich. When the number of bread slices and cheese slices is set to "0," you will see that there is "no reaction." Now, 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 elements is one cheese sandwich with two slices of bread and one slice of cheese. This equation can be written as 2 bread + cheese → cheese sandwich

With symbols, this reaction would be:

2 B + C → B₂C

The theoretical ratio of B to C is 2:1.

Classify the following combination of bread and cheese according to the limiting ingredient in the preparation of the cheese sandwich mentioned above as: bread is the limiting ingredient, cheese is the limiting ingredient, or there is no limiting ingredient.

To determine the presence of a limiting ingredient, we need to calculate the experimental ratio (ER) of B to C and compare it with the theoretical ratio (TR).

1 - 4 bread slices and 5 cheese slices.

The experimental ratio of B to C is 4:5 = 0.8:1. Since the ER < TR, the limiting ingredient is the bread.

2 - 6 bread slices and 2 cheese slices.

The experimental ratio of B to C is 6:2 = 3:1. Since the ER > TR, the limiting ingredient is the cheese.

3 - 6 bread slices and 4 cheese slices.

The experimental ratio of B to C is 6:4 = 1.5:1. Since the ER < TR, the limiting ingredient is the bread.

4 - 8 bread slices and 3 cheese slices.

The experimental ratio of B to C is 8:3 = 2.6:1. Since the ER > TR, the limiting ingredient is the cheese.

5 - 2 bread slices and 1 cheese slice.

The experimental ratio of B to C is 2:1. Since ER = TR, the is no limiting ingredient.

6 - 4 bread slices and 1 cheese slice.

The experimental ratio of B to C is 4:1. Since the ER > TR, the limiting ingredient is the cheese.

7 - 6 bread slices and 3 cheese slices.

The experimental ratio of B to C is 6:3 = 2:1. Since ER = TR, the is no limiting ingredient.

8 - 8 bread slices and 5 cheese slices.

The experimental ratio of B to C is 8:5 = 1.6:1. Since the ER < TR, the limiting ingredient is the bread.
