To prepare 0.20 L of a 0.18 M solution of \(AlCl_{3}\) , you will need to use 0.071 L of a stock solution of \(AlCl_{3}\) with a concentration of 0.30 M.

To calculate the volume of the stock solution needed, we can use the following equation:

M1 * V1 = M2 * V2

where

* M1 is the molarity of the stock solution

* V1 is the volume of the stock solution

* M2 is the desired molarity of the diluted solution

* V2 is the volume of the diluted solution

In this case, we have:

* M1 = 0.30 M

* V1 = ?

* M2 = 0.18 M

* V2 = 0.20 L

Substituting these values into the equation, we get:

0.30 M * V1 = 0.18 M * 0.20 L

Solving for V1, we get:

V1 = 0.071 L

Therefore, you will need to use 0.071 L of a stock solution of \(AlCl_{3}\)with a concentration of 0.30 M to prepare 0.20 L of a 0.18 M solution of \(AlCl_{3}\).

Two isotopes of any particular element differs on the count of number of neutrons present on its nucleus.

Isotopes are particular atomic species (or nuclides, as specialized term) of a similar component. They have a similar nuclear number (number of protons in their cores) and position in the occasional table (and subsequently have a place with a similar synthetic component), however contrast in nucleon numbers (mass numbers) because of various quantities of neutrons in their cores. While all isotopes of a given component have practically similar substance properties, they have different nuclear masses and actual properties.

The term isotope is framed from the Greek roots isos and topos , signifying "a similar spot"; consequently, the importance behind the name is that various isotopes of a solitary component possess a similar situation on the periodic table.

To combine ions to form ionic compounds, we need the combine in such a way that it gets neutral charge.

We can combine each anion with each cation to get the 4 compounds we need.

To combine SO₄²⁻ with Pb⁴⁺ we first find the Least Common Multiple of their charges, 2 and 4.

They have the factor 2 in common, so the LCM is 4. This is the final charge of each that will cancel out.

To get 4+, we only need 1 Pb⁴⁺.

To get 4-, we need 2 SO₄²⁻.

So, the formula is:

Pb(SO₄)₂

To combine SO₄²⁻ with NH₄⁺ is easier because one of them has single charge. In this case, we can simply pick one of the multiple charge ion and the same amount that will cancel its charge of the single charged one.

So, we picke 1 SO₄²⁻, ending with 2-.

And we picke 2 NH₄⁺, ending with 2+.

The formula:

(NH₄)₂SO₄

To combine C₂H₃O₂⁻ with Pb⁴⁺ we do the same, because the anion is single charged.

Pick 1 Pb⁴⁺, ending with 4+.

Pick 4 C₂H₃O₂⁻, ending with 4-.

The formula:

Pb(C₂H₃O₂)₄

To combine C₂H₃O₂⁻ with NH₄⁺, both have same charge, so we just need one of each and their charges will cancel out.

The formula:

NH₄C₂H₃O₂

So, the formulas are:

A solution composed of aspartic acid and sodium hydroxide would be considered a buffer. The correct order of increasing acid strength is: d. HBrO < HBrO2 < HBrO3 < HBrO4.

A solution composed of aspartic acid and sodium hydroxide would be considered a buffer because aspartic acid is a weak acid and sodium hydroxide is a strong base. In the presence of a weak acid and its conjugate base, the solution can resist changes in pH when small amounts of acids or bases are added. This characteristic is the definition of a buffer.

For the acid strength order question, placing the following in order of increasing acid strength: HBrO2, HBrO3, HBrO, HBrO4. The correct order is:

d. HBrO < HBrO2 < HBrO3 < HBrO4

The increasing acid strength is related to the increasing number of oxygen atoms bonded to the central bromine atom. As the number of oxygen atoms increases, the acidity of the compound also increases due to the greater ability to stabilise the negative charge on the conjugate base after losing a proton (H+).

Approximately 12.87 grams of CO2 (in its solid form) would be needed to fill a 6.5L bag with CO2 gas.

To determine the mass of CO2 (carbon dioxide) needed to fill a 6.5L bag with CO2 gas, we need to consider the density of CO2 and use it to convert the volume of gas to mass.

Carbon dioxide exists in both gaseous and solid forms. The solid form, CO2(s), is commonly known as dry ice. When it sublimes, it directly converts from a solid to a gas without passing through a liquid state.

To find the mass of CO2 needed, we first need to know the density of CO2 in its gaseous state. The density of CO2 gas can vary depending on temperature and pressure. However, at standard temperature and pressure (STP), which is defined as 0 degrees Celsius and 1 atmosphere of pressure, the density of CO2 gas is approximately 1.98 grams per liter (g/L).

Now, let's calculate the mass of CO2 needed to fill the 6.5L bag:

Mass = Volume × Density

Mass = 6.5 L × 1.98 g/L

Mass ≈ 12.87 grams

Therefore, approximately 12.87 grams of CO2 (in its solid form) would be needed to fill a 6.5L bag with CO2 gas.

It's important to note that the actual mass required may vary depending on factors such as temperature, pressure, and the specific properties of the CO2 being used.

Additionally, this calculation assumes that the CO2 undergoes a complete conversion from solid to gas, without any losses or changes in density during the process.

a) The sphere emits thermal radiation at a rate of 139.75 Watts.

b) The sphere absorbs thermal radiation at a rate of 37.66 Watts.

c) The sphere's net rate of energy exchange is 102.09 Watts.

To calculate the rates of thermal radiation emission and absorption, we can use the Stefan-Boltzmann law, which states that the rate of thermal radiation emitted or absorbed by an object is proportional to its surface area, temperature, and the Stefan-Boltzmann constant.

a) The rate of thermal radiation emitted by the sphere can be calculated using the formula:

Emitting Rate = emissivity * surface area * Stefan-Boltzmann constant * (\(temperature^4 - environment\ temperature^4\))

Plugging in the given values:

Emitting Rate = \(0.924 * (4\pi * (0.457)^2) * 5.67 \times 10^{-8} * ((32.2 + 273.15)^4 - (82.9 + 273.15)^4)\)

Emitting Rate ≈ 139.75 Watts

b) The rate of thermal radiation absorbed by the sphere can be calculated in a similar way but using the environment temperature as the object's temperature:

Absorbing Rate = emissivity * surface area * Stefan-Boltzmann constant * (\(environment\ temperature^4 - temperature^4\))

Plugging in the given values:

Absorbing Rate = \(0.924 * (4\pi * (0.457)^2) * 5.67 \times 10^{-8} * ((82.9 + 273.15)^4 - (32.2 + 273.15)^4)\)

Absorbing Rate ≈ 37.66 Watts

c) The net rate of energy exchange is the difference between the emitting rate and the absorbing rate:

Net Rate = Emitting Rate - Absorbing Rate

Net Rate = 139.75 Watts - 37.66 Watts

Net Rate ≈ 102.09 Watts

Therefore, the sphere emits thermal radiation at a rate of 139.75 Watts, absorbs thermal radiation at a rate of 37.66 Watts, and has a net rate of energy exchange of 102.09 Watts.

Note: The units for all the rates are Watts.

Anode half-reaction: Zn(s) + 2OH-(aq) -> ZnO(s) + H2O(l) + 2e⁻

Cathode half-reaction: Ag2O(s) + H2O(l) + 2e- -> 2Ag(s) + 2OH⁻(aq)

Overall cell reaction: 2Zn(s) + 4Ag2O(s) + 4H2O(l) -> 2ZnO(s) + 8Ag(s) + 4OH-(aq)

Anode half-reaction: Zn(s) + 2OH-(aq) -> ZnO(s) + H2O(l) + 2e⁻

When the silver-zinc button battery discharges, at the anode (the negative terminal), zinc metal (Zn) reacts with hydroxide ions (OH⁻) from the electrolyte solution (potassium hydroxide or KOH). This reaction produces zinc oxide (ZnO), and water (H2O), and releases two electrons (2e⁻).

Cathode half-reaction: Ag2O(s) + H2O(l) + 2e⁻ -> 2Ag(s) + 2OH⁻(aq)

At the cathode (the positive terminal), which is made of silver oxide (Ag2O) in the silver-zinc button battery, a reaction occurs. Silver oxide reacts with water and accepts two electrons, resulting in the formation of silver metal (Ag) and hydroxide ions (OH⁻).

Overall cell reaction: 2Zn(s) + 4Ag2O(s) + 4H2O(l) -> 2ZnO(s) + 8Ag(s) + 4OH⁻(aq)

When both the anode and cathode reactions are combined, we get the overall cell reaction. In this case, two zinc atoms (2Zn) from the anode react with four silver oxide molecules (4Ag2O) from the cathode. Additionally, four water molecules (4H2O) are involved in the reaction.

Most other compounds have the same physical appearance as water especially when in liquid form.

The mass of zinc sulfide formed when 25.0 g of zinc are combined with 30.0 g of sulfur is 37.3 g.

The balanced compound condition for the response among zinc and sulfur is:

Zn + S → ZnS

As indicated by the situation, one mole of zinc responds with one mole of sulfur to frame one mole of zinc sulfide. To decide how much item framed, we want to track down the restricting reactant.

The molar mass of zinc is 65.38 g/mol, while the molar mass of sulfur is 32.06 g/mol. Thusly, 25.0 g of zinc is comparable to 25.0 g/65.38 g/mol = 0.383 moles of zinc, and 30.0 g of sulfur is identical to 30.0 g/32.06 g/mol = 0.936 moles of sulfur.

Since the response among zinc and sulfur has a 1:1 mole proportion, the restricting reactant will be the reactant with the more modest number of moles, which is zinc. Hence, every one of the 0.383 moles of zinc will respond with 0.383 moles of sulfur to create 0.383 moles of zinc sulfide.

The molar mass of zinc sulfide is 97.44 g/mol. Consequently, the mass of zinc sulfide framed can be determined by duplicating the quantity of moles of zinc sulfide by its molar mass:

mass of ZnS = 0.383 moles * 97.44 g/mol = 37.3 g

Hence, 37.3 grams of zinc sulfide are shaped.
