Considering the ideal gas law, the mass of hydrogen is 24.552 grams.
An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P× V = n× R× T
In this case, you know:
P= 1 atmV= 1 m³= 1000 Ln= ?R= 0.082[tex]\frac{atmL}{molK}[/tex]T= 25 °C= 298 °KReplacing in the ideal gas law:
1 atm× 1000 L = n× 0.082[tex]\frac{atmL}{molK}[/tex]× 298 K
Solving:
[tex]n=\frac{1 atmx1000 L}{0.082 \frac{atmL}{molK}x298 K}[/tex]
n= 40.92 mol
The mol of syngas mixture is 40.92 mol.
Syngas mixture contains 30.0% hydrogen. So, there is a mol fraction of [tex]x_{hydrogen} =[/tex]0.3 . Thus, the mols of hydrogen in syngas mixture is calculated as:
40.92 moles of syngas mixture× 0.3= 12.276 moles of hydrogen
Finally, being the molar mass of hydrogen H₂ 2 [tex]\frac{g}{mole}[/tex], then the mass is:
[tex]12.276 molesx\frac{2 grams}{1 mole}[/tex]= 24.552 grams
In summary, the mass of hydrogen is 24.552 grams.

Question 24 of 25
How can one tell if a reaction is a redox reaction?
O A. Elements change phases.
O B. A precipitate is formed.
O C. Spectator ions are present.
O D. Electrons are gained and lost.
Answer:
D. Electrons are gained and lost
Explanation:
When electrons are gain and lost, redox reaction takes place. In redox reaction, reduction and oxidation tales place simultaneously. Therefore, option D is correct.
What is redox reaction ?Redox reactions include a change in the oxidation state of the substrate. When electrons are lost or the oxidation state increases, it is called oxidation; when they are gained or the oxidation state decreases, it is called reduction.
Redox reactions are those in which there is a change in the oxidation number, with both an increase and a drop in number. The reaction called non-redox if this does not take place.
Oxidation and reduction always occur jointly because any loss of electrons by one substance must be followed by a gain of electrons by another. Therefore, oxidation-reduction processes or simply redox reactions are other names for electron-transfer events.
Thus, option D is correct.

Explanation:
Labor unions arose in the nineteenth century as increasing numbers of Americans took jobs in factories, mines, and mills in the growing industrial economy.
The Knights of Labor, founded in 1869, was the first major labor organization in the United States. The Knights organized unskilled and skilled workers, campaigned for an eight hour workday, and aspired to form a cooperative society in which laborers owned the industries in which they worked.
The Knights’ membership collapsed following the 1886 Haymarket Square riot in Chicago. By 1886 the American Federation of Labor (AFL), an alliance of skilled workers’ trade unions, was growing.

Nylon is a synthetic material that has many uses. It is used in the production of machine parts, cookware, and fabric. Nylon is made from petroleum and natural gas. Suppose that there were a shortage of petroleum and natural gas. What would companies that produce nylon likely need to do? A. identify a different natural resource that nylon could be made from B. search for nylon in many different parts of the earth C. convert existing nylon back into petroleum and natural gas D. find a way to make nylon without using natural resources
In case of a shortage in petroleum and natural gas, a company should find a way to make nylon without using natural resources.
Nylon is a very important material used in numerous applications. As a result of this, the demand for nylon as a raw material has genuinely been on the high side ever since.
However, nylon production depends on petroleum and natural gas. It is possible that there could be a shortage of these resources since they are obtained from the environment. In such cases, a company should find a way to make nylon without using natural resources.

A. Groundlings
B. Quantums
C. Spectrums
D. Amplitudes
A spectrum is a pattern is unique to a substance and can be used identify it.
According to Max Plank, energy occurs in packets called quanta. Hence, energy is not continuous but takes on discrete values which are integer multiples of a fundamental amount.
Again, when a substance is given light energy, a characteristic fingerprint is obtained. This pattern is unique to the substance that has it. These characteristics “fingerprints” are called spectrums.

Which one is the answer?
Answer:
I think 1, 4, and 5 are the answers to this question. I am not sure about 4 though.
Explanation:
You have to have a power source (1), you also have to have a way to get that power somewhere else (5), and the reason for 4 would be that the power has to come back through the power source to remain working.
4. Initially, 1 mol of oxygen (assumed to be an ideal gas) has temperature 310 K and volume 12 L. We will allow it to expand to volume 19 L. (a) What would be the final temperature if the gas expands adiabatically
Answer:
490.83 oK
Explanation:
First of all, we better agree on the meaning of the word adiabatically. It means without the loss or gain of heat. So nothing is given up to or taken from the environment.
This also assumes that no change has occurred in the pressure.
T1 = 310 oK
T2 = ?
V1 = 12 L
V2 = 19 L
T1/V1 = T2/V2
310 / 12 = x/19 Multiply both sides by 19
310*19 / 12 = T2 Multiply 310 * 19 on the left.
5890 / 12 = T2 Divide by 12
490.83 = T2

A force of 5N accelerates an object. The object mass is 50 g. What is the acceleration of an object?
Answer:
100 m/ s²
Explanation:
Newton's Second Law of Motion:
[tex] \boxed{ \mathsf{force = mass \times acceleration}}[/tex]
___________________
In the question:
Force applied = 5 N mass of the object experiencing force = 50 gNote that the quantities here must be in their SI units.
SI unit of Force is Newton(N).
SI unit of mass is kilogram(kg)
Force is already in it's SI unit, while mass isn't.
Converting mass from grams to kilograms:
1000 g = 1 kg
=> 1 g = 1/ 1000 kg
=> 50 g = 50/ 1000 kg
= 1/ 20 kg
___________________
Calculating acceleration:
[tex] \mathsf{5 = \frac{1}{20} \times acceleration }[/tex]
multiplying both sides by 20:
[tex] \implies \mathsf{5 \times 20= (\frac{1}{20} \times 20)\times acceleration }[/tex]
20 on the RHS gets canceled, for it's present on the numerator as well as the denominator.
[tex] \implies \mathsf{100= acceleration }[/tex]
So, here, we got acceleration = 100 m/s².
Since, the other quantities used in the formula are in their SI units, acceleration must be in it's SI unit as well.
The SI unit of acceleration is m/s²
___________________
Answer:
[tex] \boxed{ \mathsf{100 \:m/s^2= acceleration }}[/tex]
