The rate of second order reaction depends on the change in the concentration of the reactants.

A second order reaction is one in which the rate of reaction depends on the concentration of reactants.

For a second order reaction;

1/[A] = kt + 1/[A]o

When concentration deceresases to one-half;

1/0.1 = 0.54t + 1/0.20

1/0.1 -  1/0.20 = 0.54t

10 - 5/0.54 = t

t = 9.3 s

When concentration deceresases to one-sixteenth;

1/0.0125 = 0.54t + 1/0.20

1/0.0125 -   1/0.20 = 0.54t

80 - 5 =  0.54t

t = 80 - 5/0.54

t = 149 s

When concentration deceresases to one-ninth;

1/0.022 =  0.54t + 1/0.20

1/0.022  -   1/0.20 = 0.54t

45 - 5 =  0.54t

t = 45 - 5/0.54

t = 74 s

Volume is halved means Temperature is halved

#b

Volume is doubled means temperature is doubled

#c

Volume is tripled means temperature is trippled

Answer:

Explanation:

The relation between temperature and volume at constant pressure is given by Charles Law.

Scenario 1 : Volume is halved

⇒ Let initial volume be V

⇒ \(\frac{V}{17} = \frac{0.5V}{T}\)

⇒ T = 17 × 0.5

⇒ T = 8.5 °C

Scenario 2 : Volume is doubled

⇒ \(\frac{V}{17} = \frac{2V}{T}\)

⇒ T = 17 × 2

⇒ T = 34 °C

Scenario 3 : Volume is tripled

⇒ \(\frac{V}{17} = \frac{3V}{T}\)

⇒ T = 17 × 3

⇒ T = 51 °C

Answer:

62 L

Explanation:

We are given that:

n = 2.3 mol

R = 0.082 L*atm/(mol*K), the ideal gas constant in the required units

T = 290 K

P = 0.89 atm.

therefor:

V = nRT/P

= [(2.3 mol)(0.082 L*atm)(290 K)/(mol*K)]/(0.89 atm)

= 62 L

The volume of 2.3 mol CL2 will be 62 L.

A three-dimensional element's area of coverage. The measurement of volume is done in cubic units. Decibels are a unit of measurement for the volume of sound.

Calculation of volume.

Volume can be determined by using the formula.

PV = nRT

where, P = pressure, V = volume, n = number of moles, R = gas constant and T = temperature,

It is given that, n = 2.3 mol, T = 290 K and P = 0.89 atm.

Put the value of given data in volume equation,

V = n RT/ P

V = 2.3 mol × 0.082 × 290 /0.89

V = 62 L.

Therefore, the volume will be 62 L.

Species oxidized: Mg (magnesium)

Species reduced: Ag (silver)

Oxidizing agent: Ag (silver)

Reducing agent: Mg (magnesium)

In the given electron transfer reaction: 2Ag + Mg -> 2Ag+ + Mg²⁺

Species oxidized: Mg (magnesium)

Species reduced: Ag (silver)

Oxidizing agent: Ag (silver)

Reducing agent: Mg (magnesium)

The species being oxidized (Mg) loses electrons and undergoes oxidation, while the species being reduced (Ag) gains electrons and undergoes reduction. In this reaction, magnesium (Mg) is the reducing agent since it donates electrons and causes the reduction of silver ions (Ag+) to form elemental silver (Ag). On the other hand, silver (Ag) acts as the oxidizing agent since it accepts the electrons and causes the oxidation of magnesium (Mg) to form magnesium ions (Mg²⁺).

Overall, this reaction involves the transfer of electrons from magnesium to silver ions, resulting in the reduction of silver ions and the oxidation of magnesium.

A flame that is yellow may be the result of incomplete fuel oil combustion. When a fuel oil is burned, the reaction produces heat and various byproducts, including carbon dioxide and water vapor.

However, if there isn't enough oxygen present during the combustion process, some of the carbon will combine with hydrogen to form soot, a black carbonaceous deposit that can be seen as a yellow flame.If the flame is yellow, it indicates that fuel is being wasted since not all of the fuel is being burned.

As a result, a yellow flame is often linked to high fuel use and reduced efficiency. This can also lead to a buildup of soot, which can clog the burner nozzle and increase the risk of fire.Yellow flames might be seen in a number of applications, including propane heaters, gas grills, and oil-burning furnaces.

In order to avoid yellow flames and improve fuel efficiency, it is critical to ensure that the combustion chamber receives enough oxygen to completely burn the fuel.

The atomic ratio of carbon to oxygen in carbon monoxide (CO) is 1:1, and the atomic ratio of carbon to oxygen in carbon dioxide (CO₂) is 2:1.

Firstly, we can analyze the decomposition of carbon monoxide (CO) and carbon dioxide (CO₂) to determine the atomic ratios involved.

Let's denote the atomic ratio of carbon to oxygen in carbon monoxide as x, and the atomic ratio of carbon to oxygen in carbon dioxide as y.

According to the given data;

Decomposition of carbon monoxide (CO);

Oxygen produced = 3.36 g

Carbon produced = 2.52 g

We know that the atomic mass of carbon is 12 g/mol, and the atomic mass of oxygen is 16 g/mol. Using these values, we can calculate the number of moles for each element;

Number of moles of oxygen = mass / atomic mass = 3.36 g / 16 g/mol = 0.21 mol

Number of moles of carbon = mass / atomic mass = 2.52 g / 12 g/mol = 0.21 mol

Since the atomic ratio of carbon to oxygen in carbon monoxide is x, we can write the following equation;

0.21 mol C / (0.21 mol O) = x

Simplifying the equation, we have;

x = 1

Therefore, the atomic ratio of carbon to oxygen in carbon monoxide is 1:1.

Decomposition of carbon dioxide (CO₂);

Oxygen produced = 9.92 g

Carbon produced = 3.72 g

Following the same calculations as before;

Number of moles of oxygen = mass / atomic mass = 9.92 g / 16 g/mol = 0.62 mol

Number of moles of carbon = mass / atomic mass = 3.72 g / 12 g/mol = 0.31 mol

Since the atomic ratio of carbon to oxygen in carbon dioxide is y, we can write the following equation;

0.31 mol C / (0.62 mol O) = y

Simplifying the equation, we have;

y = 0.5

Therefore, the atomic ratio of carbon to oxygen in carbon dioxide is 1:0.5, which can be simplified to 2:1.

Answer: The ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide is 1: 1.

Explanation:

Law of constant proportion states that In a chemical substance the elements are always present in definite proportions by mass. This law is also known as 'Law of definite proportions '.

Mass of 1 atom of sulphur = 32 g

Mass of 1 atom of oxygen = 16 g

Mass of 2 atoms of oxygen =\(16g\times 2=32g\)

In formation of \(SO_2\) , 1 atom of sulfur combines with 2 atoms of oxygen and thus the mass ratio will be 32: 32= 1:1 .

Thus the ratio of mass of sulfur atom to mass of oxygen atom in sulfur dioxide is 1: 1.

If a sample of gas has a volume of 2.50 L at 236 kPa and 75.0 °C, the pressure 1.18 atm is required.

Only ideal gas is subject to the ideal gas law; vanderwaal gas is not. Here, Boyle's and Charles' gas laws are combined. As a result, the new gas pressure is 1.18 atm.

The relation between Pressure, volume, and temperature can be given as:

PV = nRT

In which:

P = pressure of  gas

V= volume of gas

n =number of moles of gas

T =temperature of gas

R = Gas constant

= 0.0821 L.atm/K.mol

Combining Boyle's and Charles' gas law

P₁V₁/T₁ = P₂V₂/T₂

{ (5.28atm) (2.50 L)} ÷348 K ={ (P2) (3.75 L)} ÷298 K

P₂ =1.18 atm

Thus, the new pressure of gas is 1.18 atm when the temperature is changed to 348K and volume is increased to 3.75 L.

When an electron passes through the magnetic field of a horseshoe magnet, the electron's direction is changed.

Path of an electron in a magnetic field

The force (F) on wire of length L carrying a current I in a magnetic field of strength B is given by the equation:

F = BIL

But Q = It and since Q = e for an electron and v = L/t you can show that :

Magnetic force on an electron = BIL = B[e/t][vt] = Bev where v is the electron velocity

In a magnetic field the force is always at right angles to the motion of the electron (Fleming's left hand rule) and so the resulting path of the electron is circular.

Therefore :

Magnetic force = Bev = mv2/r = centripetal force

v = [Ber]/m

and so you can see from these equations that as the electron slows down the radius of its orbit decreases.

If the electron enters the field at an angle to the field direction the resulting path of the electron (or indeed any charged particle) will be helical. Such motion occurs above the poles of the Earth where charges particles from the Sun spiral through the Earth's field to produce the aurorae.
