Given the recipe: 2 cups flour + 1 egg + 3 oz blueberries → 4 muffins if you have 9 cups of flour,
4 eggs and plenty of blueberries, the theoretical yield of muffins is 16.
a) true
b) false

True

Explanation:

The stoichiometry of the reaction is the proportion between the reactants and products, so it can be defined as 2:1:3:4.

With 9 cups of flor, only 8 will be used, and by the proportion, 4 eggs, and 12 oz blueberries are needed to form 16 muffins (2:1:3:4 -> 8:4:12:16). So, if there are 4 eggs and plenty of blueberries, 16 muffins can be produced.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
