Using the definitions of pH and pOH, you arrive to the following: 0.1 moles of OH ions are present per litre in a solution with a pH of 13. 11013 moles of H+ ions are present per litre in a solution with a pH of 13.
A alternative solution would have a pH of 4 and an H+ concentration of 1.0 104.The hydrogen potential is pH. It is an indicator of acidity or alkalinity that shows how many hydrogen ions are present in a substance or solution.The negative base 10 logarithm of the activity of hydrogen ions, or the quantity of hydrogen ions present, is the mathematical formula for pH:
pH = log (H+)
Similar to pOH, which expresses the concentration of hydroxyl ions in a solution as the logarithm of the concentration of OH ions with the sign reversed:
pOH=-log [OH]
It is possible to establish the following connection between pH and pOH:
pOH + pH= 14
In this instance, you are aware that the pH of the solution is 13. The pOH can be determined as follows:
pOH + 13= 14
pOH= 14 -13
pOH= 1
Next, the concentration of OH can be determined as follows:
1= - log [OH⁻]
[OH⁻]= 10⁻¹
[OH⁻]= 0.1
Lastly, 0.1 moles of OH ions are present per litre in a solution with a pH of 13.On the other hand, keeping in mind that pH = 13, the H+ concentration can be determined as follows:
13= - log [H⁺]
[H⁺]= 10⁻¹³
[H⁺]= 1×10⁻¹³
Finally, you have a different solution with 1.0 104 g/ml H+. Changing the pH definition to:
pH= - log (1.0×10⁻⁴)
Solving:
pH= 4
A alternative solution would then have a pH of 4 and an H+ concentration of 1.0 104.
In conclusion, you get that:
0.1 moles of OH ions are present per litre in a solution with a pH of 13.
11013 moles of H+ ions are present per litre in a solution with a pH of 13.
A alternative solution would have a pH of 4 and an H+ concentration of 1.0 104.

He went every day to fish very early, and each day he made a rule not to throw his nets more than four times. He started out one morning by moonlight and came to the sea-shore. He undressed and threw his nets, and as he was drawing them towards the bank he felt a great weight. He thought he had caught a large fish, and he felt very pleased. But a moment afterwards, seeing that instead of a fish he only had in his nets the carcase of an butt, he was much disappointed. Vexed with having such a bad haul, when he had mended his nets, which the carcase of the butt had broken in several places, he threw them a second time. In drawing them in he again felt a great weight, so that he thought they were full of fish. But he only found a large basket full of rubbish. He was much annoyed. "O Fortune," he cried, "do not trifle thus with me, a poor fisherman, who can hardly support his family!" So saying, he threw away the rubbish, and after having washed his nets clean of the dirt, he threw them for the third time. But he only drew in stones, shells, and mud. He was almost in despair. The main character's motivation is to keep his nets clean of dirt. support his wife and three children. be up and working by moonlight. catch stones, shells, and mud.

Read this excerpt from an argumentative essay. National landmarks are popular tourist destinations, and some of them, such as bridges or dams, perform important functions. But it costs money to keep these places running and open for tourists, so who is going to pay? When the government pays, the money comes from people's taxes. Most people would rather pay lower taxes, so the government has to cut back on its spending. Maintaining national landmarks is a luxury we cannot afford. I think there are many more important things that the government can spend our money on, such as helping people who do not have enough food, making sure all children get a good education, and keeping all of us safe. Which claim does this excerpt make
Answer:
The claim that this excerpt is making is that if the government would stop spending money on national landmarks, Americans would have to pay fewer taxes.
Explanation:
The given excerpt is talking about the money spent by the government on building landmarks. The writer claims that the money that government spends on building landmarks is unaffordable, as it takes a lot of money to maintain such buildings.
The writer claims that if the government would cease spending such a huge amount on building landmarks, they will be able to afford to spend money on helping people, providing better education to children, etc. The money that government spends on building landmarks is used from the taxes paid by American citizens.
Answer:
There are more important things the government can spend money on than the national landmarks.

Imagine hearing an audio version of "The Rainy Day" accompanied by background noises. Which of the following should you LEAST expect to hear while listening to this version of the poem? o A. rain falling O B. wind howling O C. waves crashing о O D. leaves crunching
Answer:
OD. Leaves crunching.
Explanation:
The poem "The Rainy Day" by Henry Wadsworth Longfellow is a short three-stanza poem that talks about a rainy day. The image that the poet presents is that of a dreary rainy day, with gusty winds and dead leaves.
Considering the poem is about a rainy day, the audio version will most probably be accompanied by the sounds of winds blowing, rains falling, and waves on the sea. The only noise that will be least expected will be the crunching sound of leaves, for they will be wet and not crunchy, more soggy and dead.
Thus, the correct answer is option D.

You learned about two conflicts during World War II: Pearl Harbor and the internment of Japanese Americans.
Think of a major conflict that is happening in the world today. Describe the conflict in your discussion. What are the main causes of the conflict? Why is the conflict such a big issue? Can you think of any possible solutions for this conflict?
Answer:
A big conflict in the world today is climate change. A lot of people are worried that the planet is starting to warm up, and they say that the world is gonna end in 12 years....
but on the other side of the spectrum people say that it is a normal cycle for the planet to heat up, because the planet is always heating and cooling in 10 year increments, which is why there where at least 5 ice-ages in the history of this planet.
The solution for this conflict is to do more scientific studies and be 100% sure about what we have to do before we go screwing with the planet.
