Answer:

619.465 kilometers

Explanation:

1609 m = 1 mile

so 385 miles is equal to 619465 meters (385 x 1609= 619465)

1000 meters = 1 km

so 619465 meters is 619.465 kilometers

The pressure of a gas in a tank is 3.20 ATM at 22.0°C if the temperature is increased to 60.0°C what will the new pressure in th
ruslelena [56]

Answer:

P₂ = 3.61 atm

Explanation:

Given data:

Initial pressure of tank = 3.20 atm

Initial temperature = 22.0°C

Final temperature = 60.0°C

Final pressure = ?

Solution:

Initial temperature = 22.0°C (22.0 +273 = 295 K)

Final temperature = 60.0°C (60 +273 = 333)

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

3.20 atm / 295 K = P₂/333 K

P₂ = 3.20 atm × 333 K / 295 K

P₂ = 1065.6 atm. K /295 K

P₂ = 3.61 atm

Excited lithium ions emit radiation at a wavelength of 670.8 nm in the visible range spectrum. Calculate the frequency of a phot
zzz [600]

Answer : The frequency of a photon of radiation is, 4.47\times 10^9s^{-1}

Explanation : Given,

Wavelength of the radiation = 670.8 nm

First we have to convert wavelength form 'nm' to 'm'.

Conversion used : (1nm=10^{-9}m)

So, the wavelength of the radiation = 670.8 nm = 670.8\times 10^{-9}m

Now we have to calculate the frequency of a photon of radiation.

Formula used : \nu =\frac{c}{\lambda}

where,

\nu = frequency of a photon of radiation

\lambda = wavelength of the radiation

c = speed of light = 3\times 10^8m/s

Now put all the given values in the above formula, we get the frequency of a photon of radiation.

\nu =\frac{3\times 10^8m/s}{670.8\times 10^{-9}m}

\nu =4.47\times 10^9s^{-1}

Therefore, the frequency of a photon of radiation is, 4.47\times 10^9s^{-1}

Use the standard reduction potentials located in the 'Tables' linked above to calculate the equilibrium constant for the reactio
Paladinen [302]

Answer:

Check the explanation

Explanation:

cell CuE Ecell 0.337 (-0.14) Ecl0.477 V

Since E^o_{ cell } > 0 , the value of \Delta G^o will be negative.

\Delta G^o < 0

\Delta G^o =-nFE^o_{ cell }......(1)

But

\Delta G^o =-RT ln K......(2)

From (1) and (2)

\Delta G^o =-RT ln K=-nFE^o_{ cell }

ln K =\frac{nFE^o_{ cell } }{RT }

ln K =\frac{ 2 \times 96500 \times 0.477 }{8.314 \times \left ( 25+273.15 \right ) }

ln K =37.139

K =1.3468 \times 10^{16}

Hence, the value of the equilibrium constant is 1.35 \times 10^{16}

The two reactions illustrated in the diagrams below often occur when a foreign substance enters the body.
zheka24 [161]

The specific proteins produced by cell B in response to the foreign substance are antibodies.

<h3>What are antibodies?</h3>

Antibodies are specific proteins produced by the immune cells of the body in response to a foreign substance called antigen which produces the immune response.

Antibodies are released by immune cells such as B cells.

The antibodies bind to antigen and tag them for destruction by phagocytes.

Therefore, cell B will produce antibodies.
