The reaction between potassium chloride and mercury(I) nitrate may form a precipitate of mercury(I) chloride (Hg2Cl2), while no precipitate will form when ammonium carbonate and potassium nitrate are mixed.

1. For the combination of potassium chloride and mercury(I) nitrate, we need to refer to the solubility rules to determine if a precipitate will form. According to Rule 1, chloride ions (Cl-) usually do not form precipitates unless they are combined with silver, mercury(I), or lead. Since mercury(I) is one of the exceptions, there is a possibility of a precipitate forming. Therefore, a reaction may occur between potassium chloride and mercury(I) nitrate. The formula for the precipitate, if formed, would be Hg2Cl2 (mercury(I) chloride).

2. For the combination of ammonium carbonate and potassium nitrate, we again need to refer to the solubility rules. According to Rule 2, carbonate ions (CO3^2-) usually form precipitates. However, we also need to consider Rule 3, which states that if a compound contains an ion mentioned in Rule 1 (in this case, ammonium), it will not form a precipitate. Since ammonium compounds are always soluble, no precipitate will form when ammonium carbonate and potassium nitrate are mixed. Therefore, the answer is "NP" (no precipitate).

A Hydrate is a compound containing H2O molecules. The best-known hydrates are crystalline solids that lose their fundamental structure from the removal of bound water.  Some examples of hydrate are Glauber's Salt ( sodium sulfate decahydrate, Na2.SO4.10H2O), Washing soda ( sodium carbonate decahydrate, Na2CO3∙10H2O), and the double salts known as alums.

In many cases, hydrates are coordination compounds CuSO4∙5H2O is actually [Cu(H2O)4]SO4∙4H2O where four molecules of water of hydration are coordinated to copper ion. Similarly, MgSO4.7H2O is actually [Mg(H2O)6]SO4∙4H2O.

Noble gases and hydrocarbon gases form crystalline hydrates called clathrate compounds which are relatively at low temperatures and pressure.

The molar mass of the unknown gas is approximately 130.2 g/mol. Considering that it's made up of atoms and given its molar mass, the most likely chemical formula of the gas is Xe (xenon). Xenon has a molar mass of approximately 131.29 g/mol, which is close to the calculated value.

Based on the given information, we can determine the chemical formula of the gas using Graham's Law of Effusion. Graham's Law states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. The formula is:

Rate1 / Rate2 = √(M2 / M1)

Here, Rate1 is the rate of effusion for the unknown gas, Rate2 is the rate of effusion for Cl2, M1 is the molar mass of the unknown gas, and M2 is the molar mass of Cl2.

Since the unknown gas escapes 0.735 times as fast as Cl2, we can set up the equation:

0.735 = √(M2 / M1)

Now, we need to find the molar mass of Cl2. Chlorine has a molar mass of approximately 35.45 g/mol. Cl2 has two chlorine atoms, so its molar mass is:

M2 = 2 * 35.45 = 70.9 g/mol

Next, we need to solve for M1:

0.735 = √(70.9 / M1)

Square both sides of the equation:

0.735^2 = 70.9 / M1

M1 = 70.9 / 0.735^2

M1 ≈ 130.2 g/mol

It is true that the increase in pH when adding calcium carbonate to soil is accomplished by calcium.

When calcium carbonate is added to soil, the increase in pH is accomplished by calcium.

Calcium carbonate neutralizes soil acidity by releasing calcium ions, which react with hydrogen ions present in acidic soil, forming water and raising the pH level.

The calcium ions contribute to the soil's nutrient content and can improve the structure and water-holding capacity of the soil.

The addition of calcium carbonate to soil can increase pH through the release of calcium ions.

The sample of helium gas must be cooled to approximately -220°C to reduce its volume from 5.9 L to 0.2 L at constant pressure.

According to the ideal gas law, the relationship between the volume (V), temperature (T), and pressure (P) of a gas can be expressed as PV = nRT, where n is the number of moles of the gas and R is the ideal gas constant. In this case, the pressure is constant, so we can simplify the equation to V/T = constant.

To find the final temperature required to reduce the volume from 5.9 L to 0.2 L, we can set up the following ratio:

(V1 / T1) = (V2 / T2)

Where V1 is the initial volume (5.9 L), T1 is the initial temperature (119°C + 273.15 = 392.15 K), V2 is the final volume (0.2 L), and T2 is the final temperature that we need to find.

Rearranging the equation, we have:

T2 = (V2 / V1) * T1

= (0.2 L / 5.9 L) * 392.15 K

≈ 13.28 K

Converting 13.28 K back to Celsius, we get:

T2 ≈ -259.87°C

Therefore, the sample of helium gas must be cooled to approximately -220°C (or -259.87°C) to reduce its volume from 5.9 L to 0.2 L at constant pressure.

The question should be:

There are several types of solutions, including dilute solutions, concentrated solutions, saturated solutions, unsaturated solutions, and supersaturated solutions. Each type of solution has specific characteristics that distinguish them from one another.

Dilute solutions: These solutions have a small amount of solute dissolved in a larger amount of solvent. They have a low concentration of solute particles. Concentrated solutions: Concentrated solutions have a large amount of solute dissolved in a smaller amount of solvent. They have a high concentration of solute particles. Saturated solutions: Saturated solutions contain the maximum amount of solute that can dissolve in a given amount of solvent at a particular temperature. Any additional solute added will not dissolve. Unsaturated solutions: Unsaturated solutions have not reached their maximum solute capacity and can dissolve more solute. Supersaturated solutions: These solutions contain more solute than what is normally possible at a given temperature. They are achieved by dissolving the solute at a higher temperature and then cooling the solution slowly.

The number of moles of lithium nitrate, LiNO₃, needed to make 11.4 moles of lithium sulfate, Li₂SO₄, is 22.8 moles.

To find the moles of lithium nitrate, LiNO₃, needed to make 11.4 moles of lithium sulfate, Li₂SO₄, we will use the balanced chemical equation provided:

Pb(SO₄)₂ + 4 LiNO₃ → Pb(NO₃)₂ + 2 Li₂SO₄

From the equation, we can see that 4 moles of LiNO₃ are required to produce 2 moles of Li₂SO₄. To find the moles of LiNO₃ needed for 11.4 moles of Li₂SO₄, we can set up a proportion:

(4 moles LiNO₃ / 2 moles Li₂SO₄) = (x moles LiNO₃ / 11.4 moles Li₂SO₄)

Now, solve for x:

x = (4 moles LiNO₃ / 2 moles Li₂SO₄) * 11.4 moles Li₂SO₄
x = 22.8 moles LiNO₃

Therefore, 22.8 moles of lithium nitrate (LiNO₃) will be needed to make 11.4 moles of lithium sulfate (Li₂SO₄).

Answer:

P(O₂) = 26KPa

Explanation:

Given data:

Total pressure = 150 KPa

Partial pressure of nitrogen = 100 KPa

Partial pressure of carbon dioxide = 24 KPa

Partial pressure of oxygen = ?

Solution:

According to Dalton law of partial pressure,

The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.

Mathematical expression:

P(total) = P₁ + P₂ + P₃+ ............+Pₙ

Now we will solve this  problem by using this law.

P (total) = P(O₂) + P(N₂) + P(CO₂)

150 KPa =   P(O₂) + 100 KPa + 24 KPa

150 KPa = P(O₂) + 124 KPa

P(O₂) = 150 KPa  - 124 KPa

P(O₂) = 26KPa
