Question

Which resources are required to make sweet rolls?

a) 3 lb of flour, 1 dozen eggs, 2 lb of sugar
b) 5 lb of flour, 3 dozen eggs, 2 lb of sugar
c) 760 lb of flour, 420 dozen eggs, 480 lb of sugar
d) $148.00 profit

Answer 1

The question involves determining the necessary ingredients for making sweet rolls, using knowledge from a classic pound cake recipe and applying the concept of limiting reactants, similar to a simple brownie recipe and a chemical reaction for producing water.

Step-by-step explanation:

The question asks which resources are required to make sweet rolls. The resources are related to ingredients typically used in baking. By considering a classic recipe for a pound cake, which consists of 1 pound each of eggs, butter, flour, and sugar, we can find the conversion factors needed for other recipes. For every pound of butter, you would need the same amount in pounds of the other three ingredients, sugar, flour, and eggs.

In the context of making brownies, the equation 1 box mix + 2 eggs → 1 batch brownies indicates that for every box of brownie mix, you need two eggs. Thus, if you have a dozen eggs, the limiting reactant (or ingredient) would be the number of brownie mix boxes you have. This is because the eggs are in excess given their ratio compared to the boxes of the mix.

Similarly, in the chemical reaction 2 H₂(g) + O₂(g) → 2 H₂O(l), the amount of hydrogen gas determines the amount of water that can be produced when it reacts with oxygen, following the stoichiometry of the balanced chemical equation.
