Concept introduction: The reagent in reaction that controls the amount of product formed is termed as limiting reagent. After completion of chemical reaction, the limiting reagent is fully utilized.

Answer to Problem 2RQ

Lemons are limiting ingredient as they are present in lesser quantity than required.

Explanation of Solution

Given:

The recipe of a lemonade includes 1 cup of sugar for every 6 lemons.

The number of lemons available is 12 and cups of sugar are 3.

The recipe of a lemonade includes 1 cup of sugar for every 6 lemons, which means one lemonade will be formed by the combination of 1 cup of sugar and 6 lemons.

Since one cup of sugar requires 6 lemons so, 3 cups of sugar will require lemons. But the number of lemons available is 12. Hence, lemons are limiting ingredient as they are present in lesser quantity than required.
