What is the equiliibrium constant k for a redox reaction involving the transfer of 6 mol electrons?

Answers

The equilibrium constant for a chemical reaction is equal to the value of the reaction. The equilibrium constant that is denoted by k is Keq = 1.8E4

What is equilibrium constant ?

The equilibrium constant for a chemical reaction is equal to the value of the reaction quotient at chemical equilibrium, a state that a dynamic chemical system approaches when enough time has elapsed and at which its composition has no observable tendency to change further.

We know that,[tex]\Delta G = -nFE0[/tex]

and,[tex]\Delta G = - RT ln Keq[/tex]

So, ln Keq = (nFE0 ) / (RT)         ----- (i)

E₀ = standard cell potential = 0.042 V

n = number of electrons transferred in the rxn = 6

F = 96,485 C/mol ,

 R = 8.314 J / mol * K

As T is not given so assuming it to be room temperature. So, T = 298 K

Putting all the values in equation (i):

ln Keq = (6 X 96,485 C.mol-1 X 0.042 V ) / (8.314 J mol-1 K-1 X 298 K)

ln Keq = 24314.22 C.V / 2477.572 J

Now, 1 coloumb X 1 volt = 1 joule

So, ln Keq = 24314.22 / 2477.572 = 9.814

Keq = 18288

Rounding to two significant figures:

Keq = 18000 = 1.8 X 104

So in scientific notation: Keq = 1.8E4

describe one tool or instrument, other than a thermometer, that works using the principle of thermal expansion.

Answers

The instrument, other than a thermometer, that works using the principle of thermal expansion is thermostat.

Thermostat is made up of two metals with differing expansion coefficients, Inver and Brass.

We employ it in an electrical device, it is straight at room temperature, if there is a short-circuit or any other issue and the circuit temperature suddenly rises, the thermostat's temperature will rise as well.

Thermal expansion, which typically excludes phase transitions, is the tendency of matter to change its area, volume, shape and density in response to a change in temperature. The material's coefficient of linear thermal expansion typically fluctuates with temperature and is calculated as the relative expansion divided by the change in temperature.

which of the following astronomers introduced the most widely accepted hypothesis regarding the origin of the solar system?

Answers

Astronomer who introduced the most widely accepted hypothesis regarding the origin of the solar system was Immanuel Kant in 1755.

What is solar system?

The Solar System is gravitationally bound system of the Sun and objects that orbit it. It formed 4.6 billion years ago from gravitational collapse of a giant interstellar molecular cloud. The vast majority (99.86%) of system's mass is in the Sun, with most of the remaining mass contained in the planet Jupiter. Four inner system planetsMercury, Venus, Earth and Mars—are terrestrial planets, being composed primarily of rock and metal. Four giant planets of the outer system are substantially larger and more massive than the terrestrials.

The two largest, Jupiter and Saturn, are gas giants, being composed mainly of hydrogen and helium; next two, Uranus and Neptune, are ice giants, being composed mostly of volatile substances with the relatively high melting points compared with hydrogen and helium, such as water, ammonia, and methane. All eight planets have nearly circular orbits that lie near the plane of the Earth's orbit, called the ecliptic.

There are an unknown number of smaller dwarf planets and the innumerable small Solar System bodies orbiting the Sun. Six of the major planets, six largest possible dwarf planets, and many of the smaller bodies are orbited by natural satellites, commonly called "moons" after Earth's Moon.

Two natural satellites, Jupiter's moon Ganymede and Saturn's moon Titan, are larger but not more massive than Mercury, smallest terrestrial planet, and Jupiter's moon Callisto is nearly as large. Each of the giant planets and some smaller bodies are encircled by the planetary rings of ice, dust and moonlets. The asteroid belt, which lies between orbits of Mars and Jupiter, contains objects composed of rock, metal and ice. Beyond Neptune's orbit lie Kuiper belt and scattered disc, which are populations of objects composed mostly of ice and rock.

Answers

By ideal gas approximation, the final volume is 6.84 liters.

We need to know about the ideal gas theory to solve this problem. The ideal gas is assumed that there is no interaction between particles in a gas. It can be determined by the equation

P . V = n . R . T

where P is pressure, V is volume, n is the number of moles gas, R is the ideal gas constant (8.31 J/mol.K) and T is temperature.

From the question above, we know that

V1 = 5 L

P1 = 1040 torr = 1040 / 760 atm

P2 = 1 atm

When the initial and final temperature is the same, we can use the ratio of pressure and volume as

Since the snowboarder is going up the hill at an angle of 5°, the weight of the snowboarder does not align with the traditional y-axis direction. So resolving the weight into horizontal and vertical components.

sin 5° = - [tex]W_{x}[/tex] / W

[tex]W_{x}[/tex] = - W sin 5°

The velocity of the bird can be directed such that the resultant velocity of

the bird and the wind will be in the southward direction.

component of the velocity is;

The magnitude of the velocity of the bird = 100 km/h

The direction of the bird = North-South direction

The magnitude of the velocity of the wind = 40 km/h

The direction of the wind = East-west direction

The component vector of the two velocities are;

Velocity of bird, v = -100·j

The velocity of wind, v = 40·i

The direction of the velocity of the bird will be southward if it has a

component of velocity to accommodate the velocity of the wind.

Let θ represent the angle of the direction of the bird relative to the

negative x-axis, we have;

-100 × cos(θ) = -40·i

θ ≈ 66.42° in the third quadrat, given that both the y, and x, values are

a_n=v^2/ρ

a_n=(300mm/s)^/279.5mm

a_n=322mm/s^2

Understand that the tangential acceleration is zero. Thus, write the expression of the net acceleration.

a=√a_t^2+a_n^2

a=√((0mmm/s^2)^2+(322mm/s^2)^2

a=322mm/s^2

Understand that the given information,

dy/dx=-0.5

tanθ=-0.5

θ=26.6(anticlockwise)

If a glass has an index of refraction, n = 1.52, what is the speed of light inside the glass? show calculations with equation and numbers plugged in.

Answers

If a glass has an index of refraction, n = 1.52,

The speed of light inside the glass will be [tex]1.97\times10^8m/s[/tex].

How to find the refractive index?

To find the refractive index of a material, following formula is used:

Refractive index = Speed of light in air / Speed of light in the crown glass

We are given the value of refractive index is 1.52.

We know that the speed of light is [tex]3\times10^8m/s[/tex].

We will substitute the numerical values in the formula, we get:

[tex]1.52=\frac{3\times10^8m/s}{\text{ Speed of light in crown glass} \text}\\[/tex]

[tex]\text{ Speed of light in crown glass} \text=\frac{3\times10^8}{1.52}[/tex]

Hence, the speed of light inside the glass will be [tex]1.97\times10^8m/s[/tex].

true or false: it is possible for an object to nnove for 10 seconds at a high speed and end up with an average velocity of zero.

Answers

Yes. it is possible for an object to move for 10 seconds at a high speed and end up with an average velocity of zero.

What is average velocity?

Velocity is answer to the question: How fast are you changing your position?  It's basically asking for a comparison of where you are at two different times and makes rate of change quantitative.  To make sense out of this, let's first write it as words equation:

The average velocity = (How far did you move?) / (How long did it take you?)

That way, doing either a bigger distance in the same time or the same distance in a shorter time both give a larger number to velocity and agree with our sense of what it means to move faster.

For the above question:

Average velocity is displacement over the time. Displacement is difference between your final position and your initial position. If you traveled in circular path, very fast, or very slow, and ended up back where you started, your displacement would be zero. Dividing your displacement of zero, by time your trip took, will give you an average velocity of zero.
