The partial pressures, based on the equilibrium constant, are 0.2825 atm for hydrogen, 0.0509 atm for chlorine and 1.6666 atm for HCl.

We know that:
[tex]pH_{2} + pCl_{2} + pHCl = 2 atm[/tex]

pH₂ - partial pressure of hydrogen

pCl₂ - partial pressure of chlorine

pHCl - partial pressure of HCl

We also know that the expression for the equilibrium constant looks like this:

[tex]K_{p} =\frac{pHCl^{2} }{pH_{2}*pCl_{2} } =193[/tex]

Because the total coefficients on the left and right sides of the reaction are equal (=2), then Kp = Kc. Finally, all the chlorine present in the mixture comes from HCl degradation. If we mark the partial pressure of chlorine as X, then:

[tex]\frac{(3.59-2X)^{2} }{(0.47+X)*X } =193[/tex]

When transformed, we get the following quadratic equation:

[tex]189X^{2} + 105.07X - 12.8881 = 0[/tex]

X = 0.1034

This means that we have 0.1034 moles of chlorine. We can use that to calculate the moles of hydrogen and HCl:

(0.47+0.1034) = 0.5734 moles of hydrogen;

(3.59 - 2*0.1034) = 3.3832 moles of HCl

The partial pressure of a gas (pX) in a gas mixture is equal to the molar percentage multiplied by the total pressure:

pX = P(total) * nₓ / n(total)

We can use this to calculate the partial pressures of all the gases present in the mixture:
pH₂ = 2 atm * 0.5734 mol / (0.1034 mol + 0.5374 mol + 3.3832 mol) = 0.2825 atm

pCl₂ = 2 atm * 0.1034 mol / (0.1034 mol + 0.5374 mol + 3.3832 mol) = 0.0509 atm

pHCl = 2 atm * 3.3832 mol / (0.1034 mol + 0.5374 mol + 3.3832 mol) = 1.6666 atm

When Carter went outside one summer day to check the mail, the following statements accurately identify the types of energy transfer:

Conduction, convection and radiation are all methods of heat transfer. Conduction is the transfer of heat between two solid bodies in contact. It occurs when two solid bodies of different bodies are in contact, and heat always flows from the hotter body to the colder body.

Convection occurs when heat is transferred by the flow of matter in a liquid or gas. Liquids and gases are normally poor conductors of heat, but they are able to transfer heat through convection as the molecules of the fluid carry the thermal energy as they move. Radiation is the transfer of heat in a vacuum. Unlike conduction and convection, radiation does not require a material medium, as heat is transferred by electromagnetic waves.

When carter stepped on the sidewalk, there was a temperature difference between his foot and the sidewalk. This enabled the transfer of heat from the sidewalk to his feet through conduction. The sidewalk, however, was hot because it had been exposed under the sun. Infrared red rays from the sun transfer heat by radiation to the surface of the earth, and the sidewalk absorbed some of this radiation.

Radiation is also absorbed by the wind and carried about by convection, just like the warm breeze carter felt on his face. Some radiation was absorbed by Carter's skin, which was the warmth he felt on his skin from the sunshine. The sunlight touching his face is not an example of conduction because conduction only occurs when two solid surfaces are in contact.

Answer:

There's an experiment that you can try to see if carbon dixide is heavier than air.

Explanation:

At room temperature, carbon dioxide has higher density (ρ = 1.98 kg·m -3) than air (ρ = 1.29 kg·m -3). The density of gas, however, significantly depends on its temperature. Carbon dioxide produced by burning has higher temperature than the surrounding air.

Why is CO2 heavier than the air?

Short answer is CO2 is heavier than ambient air, but it does not drift to the ground as there is a lot of mixing going on in ambient air. ... Carbon dioxide, also known by the chemical formula CO2, has a higher density than the other gases found in air, which makes CO2 heavier than the air.

Ions are separated into cations and anions.

Oxidation State

The roman numeral after iron represents the oxidation state. The oxidation state shows the hypothetical charge of an atom. Since iron can have different oxidation states, it needs to be noted using a roman numeral. Iron can either be iron (II) or iron (III), which have a 2+ and 3+ charge, respectively.

Cations

Ions are atoms that have negative or positive charges. Negative ions are called anions, and positive ions are called cations. Atoms that have almost full valence shells (5-7 valence electrons) take electrons and become anions. Atoms that have almost empty valence shells (1-3 valence electrons) lose electrons and become cations.

Iron (II) has 2 valence shell electrons, so it will be a cation. When it bonds, it will lose both valence electrons. Since atoms gain a 1+ charge for every electron it loses, iron (II) will have a 2+ charge.

At 300 degrees Celsius, the rate constant for this alternative order response is 0.850 m1 s1.

The adjectives "dilute" for results of relatively low attention and "concentrated" for results of comparatively strong focus are widely used when characterizing attention in informal, non-technical language. To concentrate a result, one must either increase the solute (such as alcohol) or decrease the detergent ( for illustration, water). To adulterate a result by disparity, one must either use more detergent or use less solute.

No more solute will dissolve after a certain point unless two substances are miscible. At this stage, the result is referred to as saturated. A product that has been impregnated with fresh solute will not dissolve, with the exception of certain circumstances.

When two or more motes meet with the proper exposure and force to create a new product, it is known as a chemical reaction. The links between the titles are broken and formed during this process.

The result of the experiment caused Rutherford to conclude that the atom mostly was made of the empty spaces and had a positively charged nucleus in it.

Rutherford assaulted extremely thin sheets of gold foil with swiftly moving alpha (∝) particles, along with his colleagues Hans Geiger and Ernest Marsden. Positively charged alpha particles have a mass that is around four times that of a hydrogen atom.

The majority of the alpha-particles, they discovered, were undeflected, and only a small percentage were bounced off the gold foil at extremely enormous angles. Some were even sent back in the direction of the source.

Rutherford thought about these findings and came to the following conclusion: The fact that the majority of alpha particles passed straight through the foil is proof that the atom is primarily made up of empty space. It was determined that there is a concentration of positive charge in the atom based on the small number of alpha particles that were deflected at large angles.

Two different samples of the matter are measured in each of these glass containers. Both of the containers show same measure for both samples of matter. The samples most likely have in common is their volume.

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in the three dimensions is referred to as its volume. It is sometimes referred to as object's capacity.

Volume is a measurement of the three-dimensional space that is occupied.

Numerous imperial units or the SI-derived units, such as the cubic meter and liter, are frequently used to quantify it numerically (such as the gallon, quart, cubic inch). Volume and length (cubed) have symbiotic relationship. The volume of container is typically thought of as its capacity, not as the amount of space it takes up. In other words, volume is the amount of fluid (liquid or gas) that the container may hold.

Volume was initially measured using naturally occurring containers of a similar shape and later with the standardized containers. Arithmetic formulas can be used to quickly calculate volume of some straightforward three-dimensional shapes. If a formula for shape's boundary is known, it is possible to use integral calculus to determine the volumes of more complex shapes. No object in dimensions of zero, one, or two has volume; in the dimensions of four and higher, the hypervolume is a concept similar to the normal volume.

The final volume of the solution is 4.5 L.

How can we calculate molality and volume of mixed solutions?
The idea of calculating molalities after combining solutions indicates that regardless of whether you change the solution's concentration or volume, the number of moles in the mixture stays the same. So, by expanding the volume of a solution by adding water, one can modify the molality or concentration of a particular molecule or ion in the solution.
The typical formula to calculate the same is M₁V₁ = M₂V₂

Given, initial molality of NH₄Br solution = M₁ = 2.25 m
Initial volume of NH₄Br solution = V₁ = 0.250 L
Final molality of NH₄Br solution = M₂ = 0.125 m
Let, final volume of NH₄Br solution = V₂
Using the relation obtained above, we have
2.25*0.250 = 0.125*V₂ ⇒ V₂ = (2.25*0.250)/0.125 = 4.5 L
Thus, the final volume after pure water addition is 4.5 L.
