What is an unsaturated solution?
O A. A solution that is not able to dissolve any of the solute
O B. A solution that cannot dissolve any more solute
O C. A solution that can still dissolve more solute
OD. A solution containing more solute than should be possible

Answers

Answer: c

Explanation:

unsaturated solution: a solution that holds less dissolved solute than is possible at a given temperature

An unsaturated solution is a solution that can still dissolve more solute. The correct option is C.

What is an unsaturated solution?

An unsaturated solution is a solution that has low concentration of solute in the solution. The quantity of solute that can be dissolved into the solution will be less than the equilibrium solubility.

In contrast, the saturated solution is the one in which there is always more solvent than the solubility equilibrium. An example of an unsaturated solution is a salt and sugar solution. An example of a saturated solution is water with a cup of salt.

So, the third statement defines the unsaturated solution, as the solution has less solute, it can always dissolve more solute in the solution.

Thus, the correct option is C. A solution that can still dissolve more solute.

What happens when a negatively charged object A is brought near a neutral object B?
A.
Object B gets a negative charge.
0
B.
Object B gets a positive charge.
C.. Object B stays neutral but becomes polarized.
D.
Object A gets a positive charge.
E.
Object A loses all its charge.

Answers

Answer/Explanation: When a negatively charged object is brought near the knob of a neutral electroscope, the negative charge repels the electrons in the knob, and those electrons move down the stem into the leaves. Excess electrons flow from the rod into the ball, and then downwards making both leaves negatively charged.

-Hope this helps! :)

The electricity charge is a property of matter. It creates a force that takes place when placed in an electrical magnetic field they can be positive or negative. They are carried by the protons and electrons the charge is a conserved property.

When you bring a negatively charged object close to the neutral part. The positive and the negative charges attract each other and positive change gets nullified and both bodies get negatively changed.

Hence the option A is correct. Object B gets a negative charge.

Summarize and explain the purpose of Swift's "A Modest Proposal." Also, explain at least two specific literary devices

Swift uses to make his points. Your answer should be at least 150 words.

Answers

Answer:

A Modest Proposal was written by Jonathan Swift in 1729, it is a satirical essay that talks about the overpopulation Ireland was facing exposed by a humorous tone, to create awareness to the problem.

Dramatic Irony:

Irony is a literary device in which the intended meaning is different from the words used, it often uses sarcasm. In dramatic irony the audience knows the mistake the character is making long before the character realizes it.

One example of irony in the essay is the ridiculous suggestion of eating babies. The readers know what bad idea it is, but the character doesn't know, creating dramatic irony.

And butchers we may be assured will not be wanting; although I rather recommend buying the children alive, and dressing them hot from the knife, as we do roasting pigs.

Anaphora:

Anaphora is the repetition of words at the beginning of successive sentences to create an impact, it is often used in political speeches and music.  Jonathan Swift uses anaphora to emphasize a change of tone making a serious proposal for readers.

Of taxing our absentees at five shillings a pound. Of using neither clothes, nor household furniture, except what is of our own growth and manufacture. Of utterly rejecting the materials and instruments that promote foreign luxury. Of curing the expensiveness of pride, vanity, idleness, and gaming in our women. Of introducing a vein of parsimony, prudence and temperance. Of learning to love our country, wherein we differ even from Laplanders, and the inhabitants of Topinamboo. Of quitting our animosities and factions, nor acting any longer like the Jews, who were murdering one another at the very moment their city was taken. Of being a little cautious not to sell our country and consciences for nothing. Of teaching landlords to have at least one degree of mercy towards their tenants.

Explanation:

The following is a student draft. It may contain errors.

(1) A nature lover and local politician in the area had been trying for three years to capture the moose on video. (2) He finally got footage of the moose crossing a river and walking through tall grass. (3) Wandering the southwest region of Sweden is a mysterious white moose. (4) While other moose are typically dark brown or black, this rare moose looks almost entirely white, with soft white velvet coating, even on its antlers. (5) Many believed that the moose's white coloring was a result of a condition called albinism. (6) This is a condition that causes the loss of pigment, or color in skin, hair, and fur. (7) It is now believed that moose with this white fur have a recessive gene that causes white fur with specks of brown. (8) While this condition is totally rare, these weird white moose continue to pop up across Europe. (9) Their population is increasing in Europe, as moose in this area face few natural predators. (10) In order to protect these ghostly creatures, hunters have chosen to avoid these animals, effectively protecting them, allowing the populations to grow. (11) These white moose have also been seen in various areas of Alaska and Canada but are most common in the vast forests of Sweden and Norway in Europe. (12) With the number of predators, such as bears and wolves, in North America, it is unlikely that the populations of white moose will increase too much. (13) The animals' white fur keep them from being able to camouflage themselves in the forest, making them easy prey.

How could sentence 11 be revised to convey the idea more precisely?
A.
Found in the cold of Alaska and Canada too, these weird white moose are most common in the vast forests of Sweden and Norway in Europe.
B.
These white moose have also been seen all over the state of Alaska and the country of Canada but are most common in Sweden and Norway.

In literature, alliteration is the conspicuous repetition of identical initial consonant sounds in successive or closely associated syllables within a group of words, even those spelled differently. As a method of linking words for effect, alliteration is also called head rhyme or initial rhyme. For example, "humble house," or "potential power play." A familiar example is "Peter Piper picked a peck of pickled peppers". "Alliteration" is from the Latin word littera, meaning "letter of the alphabet"; it was first coined in a Latin dialogue by the Italian humanist Giovanni Pontano in the 15th century. Alliteration is used poetically in various languages around the world, including Irish, German, Mongolian, Hungarian, American Sign Language, Somali, Finnish, Icelandic.

Why do you think Fantine uses the statement it is not cowardliness and gluttony that have made what I am in her appeal to javert?

Answers

Did you forget to mention that this question is about "The miserable ones" written by Victor Hugo.

Answer:

She uses this statement to justify her condition and to obtain freedom from prison.

Explanation:

Fantine is a single mother and her daughter is guilty of a family that owns a pension. Fantine pays seven francs a month for this family to use in the expenses of her daughter (called Cosete). However, the family that takes care of Fantine's daughter, exploits the child, in addition to asking Fantine for more and more money.

Fantine doesn't want her daughter to be in need and ends up working more and more and handing over her salary to her daughter's care. However, the family that takes care of Cosete keeps asking for more money, which makes Fantine sell her hair, her teeth and become a prostitute, to get enough money.

All of this makes Fantine very sick and looks deplorable, but she continues to work to pay for her daughter's expenses. One day a man insults Fantine, she becomes possessed of anger, attacks this man and is arrested by Javert, the city police inspector.

Javert is extremely disgusted by Fantini's appearance and situation, she begs to be released since she needs to work and therefore says: "is not cowardliness and gluttony that have made what I am".
