Answer :

The average kinetic energy is, 7.659\times 10^{-21}J

The root mean square speed is, 679.02m/s

Explanation:

(a) The formula for average kinetic energy is:

K.E=\frac{3}{2}kT

where,

k = Boltzmann’s constant = 1.38\times 10^{-23}J/K

T = temperature = 370 K

Now put all the given values in the above average kinetic energy formula, we get:

K.E=\frac{3}{2}\times (1.38\times 10^{-23}J/K)\times (370K)

K.E=7.659\times 10^{-21}J

The average kinetic energy is, 7.659\times 10^{-21}J

(b) The formula used for root mean square speed is:

\nu_{rms}=\sqrt{\frac{3kN_AT}{M}}

where,

\nu_{rms} = root mean square speed

k = Boltzmann’s constant = 1.38\times 10^{-23}J/K

T = temperature = 370 K

M = atomic mass = 0.02 kg/mole

N_A = Avogadro’s number = 6.02\times 10^{23}mol^{-1}

Now put all the given values in the above root mean square speed formula, we get:

\nu_{rms}=\sqrt{\frac{3\times (1.38\times 10^{-23}J/K)\times (6.02\times 10^{23}mol^{-1})\times (370K)}{0.02kg/mol}}

\nu_{rms}=679.02m/s

The root mean square speed is, 679.02m/s

Choose the best statement of the octet rule from those listed below atoms lose 8 electrons to become valent atoms lose 8 electro
Mnenie [13.5K]

Answer:

atoms tend to react in order to gain 8 valence electrons

Explanation:

The octet rule describes the tendency of atoms of elements to react in order to have eight electrons in their valence shell. This is because having eight valence electrons confers stability to the atoms of these elements in the compounds they form.

The octet rule only does not apply to the transition elements or the inner transition elements as only the s and p electrons are involved. the electronic configuration in atoms having an octet is s²p⁶.

For example, sodium atom has one valence electron in its valence shell but a complete octet in the inner shell; it will react with chlorine atom which has seven valence electrons to form a stable compound, sodium chloride by donating its one valence electron in order to have an octet. Similarly, the chlorine atom will then have an octet by accepting the one electron from sodium atom.

How long would it take for 1.50 mol of water at 100.0 âc to be converted completely into steam if heat were added at a constant
defon
To convert boiling water to steam, that would involve heat of vaporization. The heat of vaporization for water at atmospheric conditions is: ΔHvap = <span>2260 J/g.

Molar mass of water = 18 g/mol

Q = m</span>ΔHvap = (1.50 mol water)(18 g/mol)(<span>2260 J/g) = 61,020 J

Time = Q/Rate = (61,020 J)(1 s/20 J) = 3051 seconds

In order to express the answer in three significant units, let's convert that to minutes.
Time = 3051 s * 1min/30 s = <em>102 min</em></span>

the volume of gas in a container was originally 3.24L, while at standard pressure 1.00 atm. what will the volume be if the press
Simora [160]
Hello!

To solve this problem, we will use the Boyle's Law, which describes how pressure changes when volume changes and vice-versa. The equation for this law is the following one, and we'll clear for V2:

P1*V1=P2*V2 \\ \\ V2= \frac{P1*V1}{P2}= \frac{3,24 L * 1 atm}{1,20 atm}= 2,7 L

So, the final volume after increasing the pressure would be 2,7 L. That means that volume decreases when the pressure increases

MA_775_DIABLO [31]

The most appropriate type of information for the government to use to make decisions is research reports containing scientific data.

<h3>What is pollution?</h3>

The term pollution has to do with the introduction of materials and energy that are harmful to the environment and also the fauna and flora.

1) The most appropriate type of information for the government to use to make decisions is research reports containing scientific data.

2) If the government committee learns about the side effects and decides the medication is not safe for public use, then the committee used an anecdote and did not use science to make the decision.

3) The type of research that might result in a law that restricts hunting of a particular species is research showing the species is endangered in other geographical areas

4) The statement that explains why a rare disease would get more research funding than a more common disease is; "organizations are concerned about the results of the research into the rare disease."

5) The product that the corporation is most likely manufacture is a sunscreen.
