The table shows the recipe and the available ingredients for making the maximum possible number of sandwiches.
making sandwiches recipe for one sandwich: 1 cheese slice, 2 lettuce leaves, 2 bread slices
total ingredients available: 8 cheese slices, 6 lettuce leaves, 6 bread slices
if the ingredients represent reactants of a chemical reaction, which of the following represents the leftover reactant?
two cheese slices
two lettuce leaves
five lettuce leaves
five cheese slices

five cheese slices

Explanation:

you need 1 cheese slices, 2 leaves, 2 bread slice per sandwich. you start out with 8 cheese slices , 6 leaves, 6 bread

so you make 3 sandwiches.

Five cheese slices

Explanation:

Limiting reagent is the chemical reactant which limits the formation of product. Excess reagent  is the chemical reactant which is left unreacted or unused.

Given:

1 cheese slice + 2 lettuce leaves + 2 bread slices = 1 sandwich

That is 2 bread slices, 2 lettuce leaves and 1 cheese slice is used for making one sandwich.

Available ingredients: 8 cheese slices + 6 lettuce leaves + 6 bread slices

Thus 6 bread slices, 6 lettuce leaves and 3 cheese slices are used for making 3 sandwiches.

Thus (8-3) = 5 cheese slices are the leftover or excess reactant.

Thus five cheese slices represent the leftover reactant.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
