What is the final volume of argon gas if 2.5 L at 94.0 kPa is compressed to a pressure of 207 kPa
Answer:
1.1 L
Explanation:
Volume and pressure are inversly proportional to each other meaning as volume increase, pressure decreases or the other way around. Use the equation V1P1=V2P2. So, it'll be (2.5L)(94.0kpa)=(207kPa)(V2). Thereby it is (2.5*94.0)/207= V2 = 1.1L. Don't forget your sigfigs which will be to 2 sigs.

Answer:
Wind and Hydroelectricity can be considered forms of solar energy.
Explanation:
Wind power is a form of solar energy because winds are caused by the heating of the atmosphere by the sun, the rotation of the Earth, and the Earth's surface irregularities. For as long as the sun shines and the wind blows, the energy produced can be harnessed to send power across the grid.
Hydroelectricity is a form of solar energy because Hydropower relies on the water cycle.
The water cycle has three steps:
Solar energy heats water on the surface of rivers, lakes, and oceans, which causes the water to evaporate.
Water vapor condenses into clouds and falls as precipitation—rain and snow.
Precipitation collects in streams and rivers, which empty into oceans and lakes, where it evaporates and begins the cycle again.

A certain element XX has four isotopes. 5.845% of XX has a mass of 53.93961 amuamu. 91.75% of XX has a mass of 55.93494 amuamu. 2.123% of XX has a mass of 56.93539 amuamu. 0.2820% of XX has a mass of 57.93328 amuamu. What is the average atomic mass of element XX? Express your answer numerically to four signif
Answer:
55.85 amu
Explanation:
Let A, B, C and D represent the four isotopes of element X.
The following data were obtained from the question:
Isotope A:
Abundance (A%) = 5.845%
Mass of A = 53.93961 amu
Isotope B:
Abundance (B%) = 91.75%
Mass of B = 55.93494 amu
Isotope C:
Abundance (C%) = 2.123%
Mass of C = 56.93539 amu
Isotope D:
Abundance (D%) = 0.2820%
Mass of D = 57.93328 amu
Average atomic mass of element X =.?
The average atomic mass of X can be obtained as follow:
Average Atomic mass = [(Mass of A × A%)/100] + [(Mass of B × B%)/100] + [(Mass of C × C%)/100] + [(Mass of D × D%)/100]
Average Atomic mass = [(53.93961 × 5.845)/100] + [(55.93494 × 91.75)/100] + [(56.93539 × 2.123)/100] + [(57.93328 × 0.2820)/100]
= 3.15277 + 51.32031 + 1.20874 + 0.16337
= 55.84519 ≈ 55.85
Therefore, the average atomic mass of X is 55.85 amu
The uncertainty in the measurement 0.0035 mg is:_______ A) + 0.1 mg B) + 0.01 mg C) 0.001 mg D) + 0.0001 mg
Answer:
The correct option is (D).
Explanation:
Uncertainty means lack of certainty in any calculations. It is the quantification of doubts after the calculations are done.
In this problem, we need to find the uncertainty in the measurement 0.0035 mg. There are 4 numbers after decimal. It means uncertain digit 1/10000 is the smallest scale division.
Hence, the uncertainty in the measurement 0.0035 mg is +0.0001 mg
when the temperature of a sample of liquid increases , what else increases ?
Answer:
Its kinetic energy.
Explanation:
In a liquid, the molecules are so close together that there is very little empty space. A liquid also has a definite volume, because molecules in a liquid do not break away from the attractive forces. The molecules can, however, move past one another freely, and so a liquid can flow, can be poured, and assumes the shape of its container.
An increase in the temperature of a liquid causes an increase in the average speed of its molecules. As the temperature of a liquid increases, the molecules move faster thereby increasing the liquid's kinetic energy.

The absolute temperature of a fixed mass of ideal gas is tripled while its volume remains constant. The ratio of the final pressure of the gas to its initial pressure is
Answer:
3 : 1
Explanation:
The following data were obtained from the question:
Initial temperature (T₁) = T
Initial pressure (P₁) = P
Final temperature (T₂) = 3T
Final pressure (P₂) =..?
Since the volume is constant, we shall use the following formula P₁ /T₁ = P₂ /T₂ to obtain the final pressure. This is illustrated below:
P₁ /T₁ = P₂ /T₂
P/T = P₂ /3T
Cross multiply
T × P₂ = P × 3T
Divide both side by T
P₂ = P × 3T /T
P₂ = P × 3
P₂ = 3P
Therefore, the final pressure is tripled.
Finally, we shall determine the ratio of the final pressure to the initial pressure as follow:
Initial pressure (P₁) = P
Final pressure (P₂) = 3P
Final pressure (P₂) : Initial pressure (P₁)
P₂ : P₁ => 3P/P
P₂ : P₁ => 3 : 1
Therefore, the ratio of the final pressure to the initial pressure is 3 : 1
Enter the full electron configuration for S2�. What is the atomic symbol for the noble gas that also has this electron configuration?
Answer:
1. Electronic configuration of sulphide ion S²¯ (18) => 1s² 2s²2p⁶ 3s²3p⁶
2. Ar
Explanation:
1. S²¯ simply indicates that the sulphur atom (S) has gained two extra electrons.
Thus we shall write electron configuration of sulphur (S) and sulphide ion (S²¯) as follow:
The electronic configuration of S²¯
S (16) => 1s² 2s²2p⁶ 3s²3p⁴
S²¯ (18) => 1s² 2s²2p⁶ 3s²3p⁶
2. Determination of the noble gas element that has the same electronic configuration as S²¯.
This is illustrated below:
Sulphur (S) has 16 electrons while the sulphide ion (S²¯) has extra 2 electrons making it to have a total electron of 18. Observing the elements in the periodic table, only Argon has 18 electrons with electronic configuration as:
Ar (18) => 1s² 2s²2p⁶ 3s²3p⁶
Therefore, sulphide ion (S²¯) has the same electronic configuration as Argon (Ar).

A) It limits the nuclear spin to certain allowed spin states.
B) It allows random orientation of nuclear magnetic moments.
C) It causes the nucleus to spin.
D) It holds the sample in place.
Answer:
A) It limits the nuclear spin to certain allowed spin states.
Explanation:
A nucleus with an odd atomic number or an odd mass number has a nuclear spin, which can be observed through NMR.
A proton is the simplest nucleus, and its odd atomic number of 1 implies that it has one spin. We can visualize a spinning proton as a positively charged rotating sphere. This movement of a charged particle is like an electric current in a wired loop. It generates a magnetic field called the magnetic moment. When a small magnetic bar is placed in the field of a larger magnet, it rotates to align itself with the field of the larger magnet, a lower energy arrangement than an orientation against the field. Quantum mechanics requires that the proton's magnetic moment is aligned with the external field or against the field. The lowest energy state with the proton aligned with the field is called the spin alpha state (α spin). The higher energy state with the proton aligned against the external magnetic field is called the beta spin state (β spin).
In the absence of an external magnetic field, the magnetic moments of the protons have random orientations. When an external magnetic field is applied, each proton in a sample it assumes β state or α state. Because the state of spin α is lower in energy, there are more α spins than β spins.

Using the mmoles of (35)-2,2,-dibromo-3,4-dimethylpentane calculated earlier and the molecular weight of the product (962 g/mol). Predict the theoretical 1 0096 yield of the product in grams. Round to the hundredths place.
Answer:
The yield of the product in gram is [tex]\mathsf{{w_P}=0.26 \ gram}[/tex]
Explanation:
Given that:
the molecular mass weight of the product = 96.2 g/mol
the molecular mass of the reagent (3S)-2,2,-dibromo-3,4-dimethylpentane is 257.997 g
given that the millimoles of the reagent = 2,7 millimoles = [tex]2.7 \times 10^{-3} \ moles[/tex]
We know that:
Number of moles = mass/molar mass
Then:
[tex]2.7 \times 10^{-3} = \dfrac{ mass}{257.997}[/tex]
[tex]mass = 2.7 \times 10^{-3} \times 257.997[/tex]
mass = 0.697
Theoretical yield = (number of moles of the product/ number of moles of reactant) × 100
i.e
Theoretical yield = [tex]\dfrac{n_P}{n_R}\times 100\%[/tex]
where;
[tex]n_P = \dfrac{w_P}{m_P}[/tex] and [tex]n_R = \dfrac{w_R}{m_R}[/tex]
Theoretical yield = [tex]\dfrac{(\dfrac{w_P}{m_P})}{(\dfrac{w_R}{m_R})} \times 100\%[/tex]
Given that the theoretical yield = 100%
Then:
[tex]100\% =\dfrac{(\dfrac{w_P}{m_P})}{(\dfrac{w_R}{m_R})} \times 100\%[/tex]
[tex]\dfrac{w_P}{m_P}=\dfrac{w_R}{m_R}[/tex]
[tex]{w_P}=\dfrac{w_R \times m_P}{m_R}[/tex]
where,
[tex]w_P[/tex] = derived weight of the product
[tex]m_P =[/tex]the molecular mass of the derived product
[tex]m_R =[/tex] the molecular mass of the reagent
[tex]w_R[/tex] = weight in a gram of the reagent
[tex]{w_P}=\dfrac{w_R \times m_P}{m_R}[/tex]
[tex]{w_P}=\dfrac{0.697 \times 96.2}{257.997}[/tex]
[tex]\mathsf{{w_P}=0.26 \ gram}[/tex]
