Answer:
The molar mass = 39.4 g/mol
Explanation:
The given parameters are;
The pressure at which the gas was measured = 1.3 atm.
The temperature of the gas = 47°C
The measured density of the gas = 1.95 g/L
By the combined gas equation, we have;
[tex]P \cdot V = n \cdot R \cdot T[/tex]
Where;
n = Number of moles = m/MM
P = Pressure = 1.3 atm
V = Specific, Molar Volume
T = Temperature = 47 °C = 320.15 K
R = Universal Gas Constant = 0.08205 L·atm/(mol·K)
ρ = The density = MM/V
Where;
MM = Molar mass
Therefore, V = MM×ρ
[tex]V/m= \dfrac{1/(MM) \cdot R \cdot T}{P}[/tex]
[tex]\rho= \dfrac{1/(MM) \cdot R \cdot T}{P}[/tex]
[tex]MM = \dfrac{\rho \cdot R \cdot T}{P} =\dfrac{ 1.95 \times 0.08205 \times 320.15} {1.3} = 39.4 \ g/mol[/tex]

A desk is being sold at a 40% discount. The sale price is $420. What was its original
price ?
Original price is $700
The desk being sold at a 40% discount means that there is a discount of 40% from the desk real price.
Discount rate = 40%
The sales price = $420
The original sales price = ?
Original sales price = Sales price / (1 - Rate)
Original sales price = $420 / (1 - 40%)
Original sales price = $420 / 0.60
Original sales price = $700
In conclusion, the original price of the desk is $700
Proof-check: $700 x 40% discount = $280 discount. The actual amount paid is $420 ($700 - $280)

One type of pollutant that was dumped into Lake Washington was raw
sewage that contained human wastes. How would a sewage treatment plant
have been able to solve the lake's pollution problem?
A. Turn the raw sewage into pure water,
B. Remove the organic materials from the sewage,
C. Transfer the raw sewage to a larger body of water,
D. Dilute the raw sewage with water,
Answer:
The correct option is;
B. Remove the organic materials from the sewage
Explanation:
In water treatment plants, floating the and settling solid wastes (by gravity) materials are removed and further process of sedimentation, screening grit removal are performed, to segregate and remove form solid wastes. Sedimentation tanks known as primary clarifiers are used to remove suspended solid wastes.
The soluble organic materials that pass through primary treatment are removed in the secondary treatment
The reduction and removal of the soluble and insoluble organic matter serves to preserve the amount of oxygen available in the final destination of the treated sewage waste water including a lake or stream.
Answer:
B. Remove the organic materials from the sewage
Explanation:
Prompt: A psychology graduate student conducted a study at the entrance to a football game at the university. The entrance was specifically for students who made the Dean's List for academic achievement during the previous semester. Some students arrived to watch the game by themselves, while others arrived in a group. As they arrived, the graduate student asked half of the students to record their attendance on an attendance sheet. The remaining half were allowed to enter the game without recording their attendance. The graduate student told every student to take one soda and one hamburger from a concessions table sponsored by the Dean's Office. She then returned to the sign-in table out of sight of the concessions. This gave the students the opportunity to take additional food. The graduate student measured the percentage of students who took additional free food. Her hypotheses were that students would take more food when they were alone and when they were not asked to sign in. The results are shown in the graph below; assume all differences are significant.
Questions: Identify each of the following in this study: Control group, Confounding variable, Independent variable, and provide an operational definition of the dependent variable. Explain how the data support or do not support each of the hypotheses. Explain why the findings cannot be generalized to all students Explain why the study is not a naturalistic observation.
Answer: The confounding variable is the Psychology graduate
The control is the food I think
Explanation:
Without the graduate there would be no other variable but with the graduate they are able to have the control and charts
Although your question is incomplete a general answer that would help you is provided ;
The control group in the study is ; The Dean's list for academic excellence
The Independent variable is ; Students who either Sign in or not , students who came in pairs or alone
Confounding variable is ; The type of game and type of food offered
The operational definition of the dependent variable is the variable that is directly affected by the actions of the Independent variable. and the dependent variable is ; students who take more food
In summary this study is a naturalistic observation because the Graduate student observes the behaviors/phenomenon of the students watching the match with little intervention and records their behavior.

finds the mass of 125 grams of sodium chloride
58.44g/mol
Explanation:
Required:
Mass of sodium chloride (NaCl)
From the periodic table, it is known that the mass of;
Sodium (Na) = 22.99g/mol
Chlorine (Cl) = 35.45g/mol
From NaCl, there are:
1 atom of sodium and;
1 atom of chlorine.
Therefore, to get the molar mass, or simply mass, of sodium chloride (NaCl), (i) multiply the mass of sodium (22.99g/mol) with the number of atoms (1) in the NaCl. i.e
22.99g/mol x 1 = 22.99g/mol
(ii) multiply the mass of chlorin (35.45g/mol) with the number of atoms (1) in the NaCl. i.e
35.45g/mol x 1 = 35.45g/mol
(iii) add the results in (i) and (ii) together. i.e
22.99 + 35.45 = 58.44g/mol
In essence, the molar mass of Sodium chloride is the sum of the molar masses of the atoms of sodium and chlorine. This is 58.44g/mol

what is a noble savage
Answer:
A noble savage is a literary stock character who embodies the concept of the indigene, outsider, wild human, an "other" who has not been "corrupted" by civilization, and therefore symbolizes humanity's innate goodness.
Explanation:
The noble savage is a concept of an uncivilized man whose goodness is not introduced in the corrupted civilization.
What do you mean by noble savage?A literary archetype known as a noble savage represents the idea of the native, outsider, wild human, an “other” who has not been “corrupted” by civilization, and hence represents humanity's inherent goodness.
The Enlightenment philosopher Jean Jacques Rousseau of the 18th century is most frequently credited with creating the modern myth of the noble savage. He held that those considered “savages” were not vicious but honorable because the original “man” was free from sin, appetite, and the concept of right and wrong.
Therefore, a concept of a primitive individual whose goodness is not introduced in the corrupted civilization is the noble savage.

would two bits be enough to assign a unique binary number to each vowel in the English language?
Answer:
No. Two bits are not enough to assign a unique binary number to each vowel in the English language.
Explanation:
The vowel in the English language is made up of 5 lowercase letters (a, e, i, o, u) and their corresponding 5 uppercase letters (A, E, I, O, U). All together, there are 10 unique vowel letters.
The number, x, of unique characters that can be stored by n bits is given by:
x = 2ⁿ
So if we have 2 bits, it implies that, the number of different characters that can be stored is:
2² = 4
Therefore, with 2 bits, there are 4 unique characters that can be stored.
But then, we need to store a total of 10 characters representing the English Language vowels. Therefore, two bits will not be enough to assign a unique binary number to each vowel.
It can also be seen this way
For two bits, we have the following possibilities:
00
01
10
11
Now, let's assume we have assigned the vowels as follows:
00 = a
01 = e
10 = i
11 = o
Then, only four of the vowel letters can be assigned a unique binary number.
Therefore, two bits are not enough to assign a unique binary number to each vowel of the English language.
We need at least 4 bits which will yield 2⁴ = 16 different combinations. And from that, we are able to assign each vowel a unique binary number like so:
Used
0000 = a
0001 = e
0010 = i
0011 = o
0100 = u
0101 = A
0110 = E
0111 = I
1000 = 0
1001 = U
Remaining:
1010
1011
1100
1101
1110
1111
10 out of 16 different combinations of binary numbers have been used by the 10 vowel characters. We will be left with 6 binary numbers. Better being surplus than being deficit.
Bits simply means binary digits
Two bits would not be enough to assign a unique binary number to each vowel in the English language.
The number of bits in a system is:
[tex]\mathbf{2^n = N}[/tex]
In this case:
n represents the number of bits i.e. 2
N represents the number of vowels i.e. 5
So, we have:
[tex]\mathbf{2^2 = 5}[/tex]
Express 2^2 as 4
[tex]\mathbf{4 = 5}[/tex]
The above equation is false, because 4 is not equal to 5
Hence, two bits would not be enough to assign a unique binary number to each vowel in the English language.

How do you think psychology might change as more and more women contribute their ideas to the field?
Explanation:
Women can contribute to the evolution of the field of psychology by contributing ideas that are more critical, innovative and less biased by some kind of sexist ideas.
Women have already contributed a lot to the field, but their studies have not received as much recognition as that of men due to discrimination arising from a society historically based on patriarchal concepts.
The statistics of psychology students currently show that women make up more than half of the students, which guarantees in the future many female contributions that can develop psychology and bring even more egalitarian and innovative concepts to the field.

Read the following passage carefully before you choose your answer.
Mrs. Jennings was a widow, with an ample jointure.1 She had only two daughters, both of whom she had lived to see respectably married, and she had now therefore nothing to do but to marry all the rest of the world. In the promotion of this object she was zealously active, as far as her ability reached; and missed no opportunity of projecting weddings among all the young people of her acquaintance. She was remarkably quick in the discovery of attachments, and had enjoyed the advantage of raising the blushes and the vanity of many a young lady by insinuations of her power over such a young man; and this kind of discernment enabled her soon after her arrival at Barton decisively to pronounce that Colonel Brandon was very much in love with Marianne Dashwood. She rather suspected it to be so, on the very first evening of their being together, from his listening so attentively while she sang to them; and when the visit was returned by the Middletons' dining at the cottage, the fact was ascertained by his listening to her again. It must be so. She was perfectly convinced of it. It would be an excellent match, for he was rich and she was handsome. Mrs. Jennings had been anxious to see Colonel Brandon well married, ever since her connection with Sir John first brought him to her knowledge; and she was always anxious to get a good husband for every pretty girl.
The immediate advantage to herself was by no means inconsiderable, for it supplied her with endless jokes against them both. At the park she laughed at the colonel, and in the cottage at Marianne. To the former her raillery was probably, as far as it regarded only himself, perfectly indifferent; but to the latter it was at first incomprehensible; and when its object was understood, she hardly knew whether most to laugh at its absurdity, or censure its impertinence, for she considered it as an unfeeling reflection on the colonel's advanced years, and on his forlorn condition as an old bachelor.
Mrs. Dashwood, who could not think a man five years younger than herself, so exceedingly ancient as he appeared to the youthful fancy of her daughter, ventured to clear Mrs. Jennings from the probability of wishing to throw ridicule on his age.
"But at least, mama, you cannot deny the absurdity of the accusation, though you may not think it intentionally ill-natured. Colonel Brandon is certainly younger than Mrs. Jennings, but he is old enough to be my father; and if he were ever animated enough to be in love, must have long outlived every sensation of the kind. It is too ridiculous! When is a man to be safe from such wit, if age and infirmity will not protect him?"
"Infirmity!" said Elinor,2 "do you call Colonel Brandon infirm? I can easily suppose that his age may appear much greater to you than to my mother; but you can hardly deceive yourself as to his having the use of his limbs!"
"Did not you hear him complain of the rheumatism? and is not that the commonest infirmity of declining life?"
"My dearest child," said her mother laughing, "at this rate you must be in continual terror of my decay; and it must seem to you a miracle that my life has been extended to the advanced age of forty."
"Mama, you are not doing me justice. I know very well that Colonel Brandon is not old enough to make his friends yet apprehensive of losing him in the course of nature. He may live twenty years longer. But thirty-five has nothing to do with matrimony."
