Argon (molecular weight 40 g/mole) is a monatomic compound. If liquid argon is confined to a container and held at a constant te

mperature of 80.5 K, what is the approximate vapor pressure of gaseous argon, assuming the liquid has no entropy and a binding energy of 0.1 eV? [Note: At 1 atm, the boiling point is 87.3 K.]

Explanation:

As the given data is as follows.

        \mu_{Ar} = kTln\frac{n}{n_{Q}}

and,     \mu_{H_{2}O} = -\Delta

        T = 80.5 K

According to the given condition,

               kTln\frac{n}{n_{Q}} = kTln\frac{P}{P_{Q}} = -\Delta

       \frac{n}{n_{Q}} = e^{\frac{-\Delta}{kT}}

                  p = nkT = n_{Q}kTe^{\frac{-\Delta}{kT}}

Therefore, putting the given values into the above equation as follows.

               n_{Q} = (10^{30}) \times (4)^{\frac{3}{2}} \times (\frac{80.5}{300})^{\frac{3}{2}}

                                 = 3.52 \times 10^{31} m^{-3}

Therefore, the required pressure is 2.14 \times 10^{4} Pa.

Why atoms in our body don’t <br><br>eject electrons?​
Zolol [24]

Answer:

When there are too many protons, some of the outer protons are loosely bound and more free to react with the electron. But most atoms do not have too many protons, so there is nothing for the electron to interact with. As a result, each electron in a stable atom remains in its spread-out wavefunction shape.

In an atom, there is a nucleus made up of neutral charged, neutrons, and positively charged protons. The reason why electrons which are negatively charged, don't fly off is due to its stronger attraction to the protons. ... This, however, still allows the electrons to move around the nucleus of an atom.

Calculate the pH during the titration of 40.00 mL of 0.1000 M HCl with 0.1000 M NaOH solution after the following additions of b
taurus [48]

Ph range is 12.53.

<h3>What is PH?</h3>

PH is a proportion of hydrogen particle focus , a proportion of the causticity or alkalinity of an answer. The pH scale for the most part goes from 0 to 14. Fluid arrangements at 25°C with a pH under 7 are acidic, while those with a pH more prominent than 7 are essential or basic. Having a reasonable pH safeguards our bodies from the back to front. Some even say that illnesses and problems can't fill in a body whose pH is in balance. The pH is a logarithmic scale, that is to say, when an answer becomes multiple times more acidic, its pH diminishes by one. In the event that an answer becomes multiple times more acidic, its pH will diminish by two. The pH scale is recognizable to a bunch of standard arrangements whose pH is laid out by peaceful accord. Essential pH standard qualities are resolved utilizing a fixation cell with transaction, by estimating the possible distinction between a hydrogen terminal and a standard cathode like the silver chloride anode.

Consider a transition of the electron in the hydrogen atom from n=3 to n=7.
kow [346]

<u>Answer:</u>

<u>For a:</u> The wavelength of light is 1.005\times 10^{-6}m

<u>For b:</u> The light is getting absorbed

<u>Explanation:</u>

  • <u>For a:</u>

To calculate the wavelength of light, we use Rydberg's Equation:

\frac{1}{\lambda}=R_H\left(\frac{1}{n_i^2}-\frac{1}{n_f^2} \right )

Where,

\lambda = Wavelength of radiation

R_H = Rydberg's Constant  = 1.097\times 10^7m^{-1}

n_f = Higher energy level = 7

n_i= Lower energy level = 3

Putting the values in above equation, we get:

\frac{1}{\lambda }=1.097\times 10^7m^{-1}\left(\frac{1}{3^2}-\frac{1}{7^2} \right )\\\\\lambda =1.005\times 10^{-6}m

Hence, the wavelength of light is 1.005\times 10^{-6}m

  • <u>For b:</u>

There are two ways in which electrons can transition between energy levels:

  1. <u>Absorption spectra:</u> This type of spectra is seen when an electron jumps from lower energy level to higher energy level. In this process, energy is absorbed.
  2. <u>Emission spectra:</u> This type of spectra is seen when an electron jumps from higher energy level to lower energy level. In this process, energy is released in the form of photons.

As, the electron jumps from lower energy level to higher energy level. The wavelength is getting absorbed.

I really need help with this ASAP<br>​
Norma-Jean [14]

Answer:

1) Reaction rate, in chemistry, the speed at which a chemical reaction proceeds. It is often expressed in terms of either the concentration (amount per unit volume) of a product that is formed in a unit of time or the concentration of a reactant that is consumed in a unit of time.

2) By collecting the hydrogen gas that is produced over water or in a syringe, rate graphs can be produced. The volume of gas produced and the time taken need to be recorded. The rate of the same reaction could be monitored by measuring the change in the mass of reactants as they react to form products.
