Answer:
Taking into account the reaction stoichiometry, the correct answer is option B): 9 grams of aluminum are necessary to produce 0.50 mol of hydrogen gas at 25°C and 1.0 atm.
Explanation:
The balanced reaccion is:
6 HCl + 2 Al → 2 AlCl₃ + 3 H₂
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
HCl: 6 moles
Al: 2 moles
AlCl₃: 2 moles
H₂: 3 moles
The atomic mass of aluminum is 27 g/mole. Then, by reaction stoichiometry, the following mass quantity of aluminum participates in the reaction:
Then you can apply the following rule of three: if by reaction stoichiometry 3 moles of H₂ are formed from 54 grams of Al, 0.50 moles of H₂ are formed from how much mass of Al?
mass of Al= 9 grams
In summary, the correct answer is option B): 9 grams of aluminum are necessary to produce 0.50 mol of hydrogen gas at 25°C and 1.0 atm
Answer:

The manufacturer who has an absolute advantage is: C. Frozen Treats.
<h3>What is a comparative advantage?</h3>
A comparative advantage can be defined as the ability of a business firm or country to produce goods and services at a lower opportunity cost than their rivals (competitors) or trade partners.
<h3>What is an opportunity cost?</h3>
An opportunity cost is also referred to as alternative forgone and it can be defined as the value, profit or benefits that are given up and forfeited by an individual or a business firm (manufacturer), in order to choose or acquire something that is deemed most significant at a particular point in time.
<h3>What is an
absolute advantage?</h3>
An absolute advantage can be defined as a measure of the ability of an individual or a business firm (manufacturer) to perform a specific economic activity such as the production of goods and services, more efficiently than another individual or business firm.
In this context, we can infer and logically deduce that the manufacturer who has an absolute advantage is Frozen Treats because it produced 150 gallons at $12.
