According to Le Chatelier’s principle, a change in pressure affects the chemical equilibrium of the reaction system under what condition?

[ad_1]

This problem is to apply Roult’s Law.

Roult’s Law states that the vapor pressure, p, of a solution of a non-volatile solute is equal to the vapor pressure of the pure solvent, Po solv, times the mole fraction of the solvent, Xsolv

p = Xsolv * Po sol

X solv = number of moles of solvent / number of moles of solution

The solvent is water and the solute (not volatile) is glycerin.

Number of moles = mass in grams / molar mass

mass of water = 132 ml * 1 g/ml = 132 g

molar mass of water = 18 g/mol

=> number of moles of water = 132 g / 18 g/mol = 7.33333 mol

mass of glycerin = 27.2 g

molar mass of glycerin:, C3H8O3: 3 * 12 g/mol + 8 * 1 g/mol + 3*16 g/mol = 92 g/mol

number of moles of glycerin = 27.2g / 92 g/mol = 0.29565

total number of moles = 7.33333 moles + 0.29565 moles = 7.62898 moles

=> X solv = 7.33333 / 7.62898 = 0.96125

=> p = 0.96125 * 31.8 torr ≈ 30.57 torr ≈ 30.6 torr.

Answer: 30.6 torr

Which of the Following is Not a principle of Roman Catholicism?

[ad_1]

Answer:

The two hundred years of Roman Peace (30 B.C. – A.D. 235) is called Pax Romana.

Explanation:

Pax romana is an expression in Latin used to refer to the long period of stability that lived the Roman Empire, characterized by both its inner calm and its external security, which allowed it to reach its maximum economic development and territorial expansion. This period was developed approximately between the fourth civil war and the crisis of the third century. In ancient times it was called Pax Augusta, a name also used nowadays, because this period began immediately after Augustus began to govern.

Unlike the previous periods of relative calm in Ancient Rome, the effects of the Pax Romana were decisive and lasting, as it ensured the development of the civilization that Rome had established around the Mediterranean, while achieving the assimilation of the “barbarian” territories and conquered populations and with it the expansion and acceptance of its administration, the Roman law and its moral and material values.

The principle of federalism is clearly evident in the U.S. constitution through the

[ad_1]

1- The correct answer is B, as one result of the Great Society was that the lives of many underprivileged Americans improved.

The Great Society was a set of US national reform programs announced by President Lyndon B. Johnson for the first time in a speech at Ohio University on May 7, 1964 and more fully illustrated on May 22, 1964 at the University of Michigan. These reform programs were subsequently presented to the Congress of the United States and largely approved during the 1960s, thanks to the consent of its supporters of the Democratic Party.

Two main goals of social reforms were the elimination of poverty and racial injustice. During this period new large spending programs were launched in the fields of education, medical care, urban problems and transport. Johnson’s “Great Society” was linked, in its objectives and policies, to President Franklin Delano Roosevelt’s New Deal program.

Some proposals of the Great Society resumed initiatives contained in the New Frontier program, interrupted by the tragic death of President John F. Kennedy. Johnson’s success in promoting and endorsing his reforms depended on his considerable congressional political influence, his persuasion, and the favorable historical circumstances resulting from the 1964 presidential elections, which allowed the Democratic Party to dominate Congress and to elect the House of Representatives with the largest number of exponents of the liberal current since 1938.

The evolution of the Vietnam war and the massive involvement of the American military machine in the conflict, however, partly undermined the success of the “Great Society” program. Growing, huge expenditures for the continuation of the war made more difficult to finance the reform programs. Representatives of the Democratic Party against the war in Vietnam complained that military spending decisively stifled the Great Society program. On the whole, however, despite growing political and economic difficulties, which forced the administration to eliminate or reduce the financing of some projects, President Johnson managed to activate a series of programs of great importance, including Medicare, Medicaid, the Older Americans Act and the federal education funding, which are still active.

2- The correct answer is C, as the Immigration and Nationality Act of 1965 was necessary because the previous existing American immigration policies were discriminatory.

On October 3, 1965, President Lyndon B. Johnson signed the law into effect, saying: “The [old] system violates the basic principle of American democracy, the principle according to which the valuation and reward of each man should be established on the basis of his merits as a man. It has been anti-American in the highest sense, because it has been unfaithful to the faith that led thousands to these shores, even before we were a country. ”

The Civil Rights Act expanded the federal government’s power.

Further Explanation:

The Civil Rights Act was one of the most important civil rights legislation passed in the 1960’s. This law essentially outlawed discrimination in the work place and public places on the basis of race, sex, national origin, gender, etc. The passing of this law was thanks in large part to the Civil Rights movement of the 1950’s and 1960’s. The goal of this law was to gain legal and social equality, especially for African American citizens.

Besides protecting the rights of African American citizens and women, this law also expanded the power of the federal government. This is due to the fact that the federal government now has the power to enforce this law and penalize individuals/companies who violate this law. Ultimately, this would help more African American citizens to join the workforce without facing discrimination.

Every option offered makes it clear that it is raining. However, the question has asked us to find the one that shows it is a dark and stormy night through action. That is precisely what the third option does:

Andy squinted in the darkness and walked headlong into the rain.

The action of squinting makes it clear that darkness surrounds Andy. The night is not only dark, though, but also stormy, since Andy walks headlong into the rain. The verbs “squint” and “walk”, combined with the nouns “darkness” and “rain” express, through action, that it is a dark and stormy night.

In evolutionary biology, mimicry is a similarity of one organism, usually an animal, to another that has evolved because the resemblance is selectively favoured by the behaviour of a shared signal receiver that can respond to both.[1] Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry evolves to protect a species from predators, making it an antipredator adaptation.[2] The resemblances that evolve in mimicry can be in appearance, behaviour, sound or scent. Mimicry may be to the advantage of both organisms that share a resemblance, in which case it is a mutualism, or mimicry can be to the detriment of one, making it parasitic or competitive. Mimicry occurs when a group of organisms,[a] the mimics, evolve to share perceived characteristics with another group, the models. The evolutionary convergence between groups is driven by the selective action of a signal-receiver or dupe.[3] Birds, for example, use sight to identify palatable insects, whilst avoiding the noxious ones. Over time, palatable insects may evolve to resemble noxious ones, making them mimics and the noxious ones models. In the case of mutualism, sometimes both groups are referred to as “co-mimics”. It is often thought that models must be more abundant than mimics, but this is not always so.[4] Mimicry may involve numerous species; many harmless species such as hoverflies are Batesian mimics of strongly defended species such as wasps, while many such well-defended species form Mullerian mimicry rings, all resembling each other. Mimicry between prey species and their predators often involves three or more species.[5]

In its broadest definition, mimicry can include non-living models. The specific terms masquerade and mimesis are sometimes used when the models are inanimate.[6][7][8] For example, animals such as flower mantises, planthoppers and geometer moth caterpillars resemble twigs, bark, leaves or flowers.[7][4][9] Many animals bear eyespots, which are hypothesized to resemble the eyes of larger animals. They may not resemble any specific organism’s eyes, and whether or not animals respond to them as eyes is also unclear.[10] Nonetheless, eyespots are the subject of a rich contemporary literature.[11][12][13] The model is usually another species, except in automimicry, where members of the species mimic other members, or other parts of their own bodies, and in inter-sexual mimicry, where members of one sex mimic members of the other.[4]

Mimesis in Ctenomorphodes chronus, camouflaged as a eucalyptus twig

Though visual mimicry through animal coloration is most obvious to humans, other senses such as olfaction (smell) or hearing may be involved, and more than one type of signal may be employed.[7][5] Mimicry may involve morphology, behaviour, and other properties. In any case, the mimetic signal always functions because it resembles that of another organism. In evolutionary terms, this phenomenon is a form of co-evolution. It can involve an evolutionary arms race if mimicry negatively affects the model, and the model can evolve a different appearance from the mimic.[4]p161 Mimicry should not be confused with other forms of convergent evolution, which occurs when species come to resemble each other by adapting to similar lifestyles that have nothing to do with a common signal receiver. Mimics may have different models for different life cycle stages, or they may be polymorphic, with different individuals imitating different models. Models themselves may have more than one mimic, though frequency dependent selection favours mimicry where models outnumber mimics. Models tend to be relatively closely related organisms,[14] but mimicry of vastly different species is also known. Most known mimics are insects,[7] though many other animal mimics are known. Plants and fungi may also be mimics, though less research has been carried out in this area.[15][16][17]
