According to the reaction represented above, about how many grams of aluminum (atomic mass 27 g) are necessary to produce 0. 50

liq [111]

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

Why is it important for teenagers to recognize when a friend needs serious help? What are

Reptile [31]

Teenagers have to recognize if their friend needs serious help because it can lead to very bad situations, if they're not treated properly. Warning signs may be distancing themselves from others, not talking a lot, getting into situations, they wouldn't want to get in before, not being in the same mood as they would always be, and even the most obvious ones where they explain their mental condition. You have to know who to turn to, if you can't provide the help that your friend needs, you can advise them to go to a therapist, call a hotline, speak with their loved ones, but you have to know that you can't brush it off, or say that "it's a phase", " stop being dramatic ", " you're too young to have these types of problems" etc. such phrases can be discouraging towards anyone and can lead to even worse situations.

Which detail is most relevant to the central idea in this excerpt? washington did not entirely accept the foreign policy recomme

natta225 [31]

The detail that is most relevant here is option A.

Washington did not entirely accept the foreign policy recommendations of Jefferson or Hamilton.

The passage that this question was gotten from was emphasizing the stance of George Washington on the politics that was in the world.

<h3>Why George Washington chose neutrality</h3>

This was during the French revolution. He refused to be on any of the sides that these two ministers suggested to him.

Out of these two ministers one was supporting the French side while the other was supporting the British. But the president chose the side of neutrality.

The reason for the neutrality stance was the fact that the United States was new. He did not want them to go to war.
