Answers

Answer: Ecosystem services are the flows of benefits which people gain from natural ecosystems, and natural capital is the stock of natural ecosystems from which these benefits flow. So, a forest is a component of natural capital, while climate regulation or timber might be the ecosystem service it provides.

A solution contains 3.95 g of carbon disulfide (CS2, molar mass = 76.13 g/mol) and 2.43 g of acetone ((CH3)2CO, molar mass = 58.08 g/mol). The vapor pressure of pure carbon disulfide and acetone at 35 oC are 515 torr and 332 torr, respectively. Assuming ideal solution behavior, calculate the vapor pressure of each of the components and the total vapor pressure above the solution. The total vapor pressure above the solution at 35 oC was experimentally determined to be 645 torr. Is the solution ideal? If not, indicate whether the solution deviates from Raoult’s law in a positive or negative manner.

Answers

Answer:

Psol = 433 torr

The solution is not ideal and the solution deviates from Raoult's law in a positive manner

Explanation:

The vapout pressure of a solution can be obtained using Raoult's law:

Psol = P°A* XA + P°B*XB

Where Psol is vapour pressure of solution

P° is vapour pressure of pure substance

X is mole fraction

As we have vapour pressure of pure carbon disulfide and acetone we need to find mole fraction of each compound to solve the vapour pressure of the solution:

Moles carbon disulfide:

3.95g CS₂ * (1mol / 76.13g) = 0.05188 moles

Moles acetone:

2.43g acetone * (1mol / 58.08g) = 0.04184 moles

Mole fraction of CS₂:

0.05188 moles / (0.05188mol + 0.04184mol) =

0.5536

Mole fraction acetone:

1 = X(CS₂) + X(Acetone)

X(Acetone) = 1 - 0.5536 = 0.4464

Solving for vapour pressure of the solution:

Psol = 515torr*0.5536 + 332torr*0.4464

Psol = 433 torr

As the experimental vapor pressure was 645torr > 433 torr (Theoretical vapor pressure), the solution is not ideal and the solution deviates from Raoult's law in a positive manner

What is the mass in grams of each of the following samples? 1.505 mol of Ti 0.337 mol of Na

Answers

Answer:

72.04g Ti and 7.75g Na

Explanation:

1.505 mol Ti x (47.87g/1 mol) = 72.04g Ti

0.337 mol Na x (22.99g/1 mol) = 7.75g Na

72.04g Ti and 7.75g Na mass in grams of these samples.

What is molecular mass ?

Molecular mass can be determined by the measure of mass related to a molecule which is otherwise called as atomic weight, means the mass of every atom present in the molecule.

For example, water have 2 hydrogen atoms and 1 oxygen atom, the molecular mass of water is equals to  the normal atomic mass of hydrogen increased by two or more the atomic mass of oxygen.

molecular mass can be controlled by many factors like Mass Spectrometry which is used to decide the mass of little molecule which is otherwise called as monoisotopic mass.

It can also be controlled by Hydrodynamic Strategy requires calibration and  determine the relative atomic weight; Static Light Scattering where the  Molecular weight is determined from the measure of light dispersed utilizing the Zimm technique.

So, 1.505 mol Ti x (47.87g/1 mol) = 72.04g Ti

0.337 mol Na x (22.99g/1 mol) = 7.75g Na, hence the answer is 72.04g Ti and 7.75g Na

Can someone please help with chemistry? Lead has a density of 10.5 g/cm^3. What is the diameter of a lead ball that has a mass of 500.0g? Report your answer in cm.

Answers

Density = Mass / Volume

10.5 = 500 / x

10.5x = 500

x = 50 cm^3 (1 sig fig) volume of the sphere

Volume of a sphere = 4/3 pi r^2

pi = 3.14 r = radius

50 = 4/3 pi r^3

50•3/4 = pi r^3

37.5 = pi r^3

37.5/pi = r^3

11.9 = r^3

cube root(11.9) = r

2.3 = r

Diameter = 2•radius

Diameter = 2 • 2.3

Diameter = 5 cm (1 sig fig) diameter

when the temperature of a sample of liquid increases , what else increases ?

Answers

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.

Answers

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).

An object is a regular, rectangular, solid with dimensions of 2 cm by 3cm by 2cm. It has a
mass of 24 g. Find its density.

Answers

Answer:

2

Explanation:

Density = mass/volume

m=24

v=2*3*2=12

24/12=2

Answer:

[tex]\boxed {\tt d= 2 \ g/cm^3}[/tex]

Explanation:

Density can be found using the following formula.

[tex]d=\frac{m}{v}[/tex]

where [tex]m[/tex] is the mass and [tex]v[/tex] is the volume.

We know the mass is 24 grams. We must find the volume.

Since it is a rectangle, the volume can be found using the following formula.

[tex]v=l*w*h[/tex]

The length is 2 centimeters, the width is 3 centimeters and the height is 2 centimeters.

[tex]v= 2 \ cm * 3 \ cm * 2\ cm[/tex]

[tex]v= 6 \ cm^2 * 2\ cm[/tex]

[tex]v= 12 \ cm^3[/tex]

Now we know the volume, and can substitute it into the density formula.

[tex]d=\frac{m}{v}[/tex]

[tex]m= 24 \ g\\v= 12 \ cm^3[/tex]

[tex]d=\frac{24 \ g}{12 \ cm^3}[/tex]

[tex]d= 2 \ g/cm^3[/tex]

The density is 2 grams per cubic centimeter.

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.

What is the function of the magnet in NMR?
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.

Answers

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.

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

Answers

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
