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
Explanation:
Relevance and reliability are the two primary qualities that make accounting information useful for decision making.
Relevance: Relevant information is capable of making changes or differences in decision making by helping in forming predictions about the results of past, present, and upcoming events for correct expectations.
Accuracy: It depends on whether the information, numbers, and descriptions match what happened earlier and what exactly existed.
A patient who has had multiple bloods draws from the same vein may notice some inflammation in the area. This is referred to as phlebitis. This is further explained below.

Answer:
In the current climate, in which nearly half of states are cutting appropriations to the enterprise, and institutions are struggling to meet enrollment targets, the idea of thinking beyond survival might be tough to conceptualize for most colleges — particularly for those with under a $1 billion endowment.
Explanation:
“If all you do is think about survival, you’ll ultimately perish. You have to think about prosperity.”
That was the message delivered by Association of Governing Boards associate managing principal for institutional strategies Jim Hundrieser Sunday during the 99th annual American Council on Education meeting in Washington, DC.
