The preparation of bases involves several methods that are used to create substances with basic or alkaline properties are Reaction of metal with water, Reaction of metal oxide with water, Neutralization reaction, Ammonia gas dissolving in water and Partial neutralization of a strong base with a weak acid.

Reaction of metal with water: Certain metals, such as sodium or potassium, react with water to form hydroxides. For example, sodium reacts with water to produce sodium hydroxide (NaOH).

Reaction of metal oxide with water: Metal oxides, such as calcium oxide (CaO) or magnesium oxide (MgO), can be added to water to form metal hydroxides. This process is known as hydration. For instance, when calcium oxide reacts with water, it forms calcium hydroxide (Ca(OH)2).

Neutralization reaction: Bases can be prepared by neutralizing an acid with an appropriate alkaline substance. This involves combining an acid with a base to form water and a salt. For example, mixing hydrochloric acid (HCl) with sodium hydroxide (NaOH) results in the formation of water and sodium chloride (NaCl).

Ammonia gas dissolving in water: Ammonia gas (NH3) can dissolve in water to form ammonium hydroxide (NH4OH), which is a weak base.

Partial neutralization of a strong base with a weak acid: Mixing a strong base, such as sodium hydroxide (NaOH), with a weak acid, like acetic acid (CH3COOH), results in the formation of a base with a lesser degree of alkalinity.

These methods are utilized in laboratories, industries, and various applications where bases are required, such as in the production of cleaning agents, pharmaceuticals, and chemical reactions. Each method has its own advantages and specific applications depending on the desired base and its properties.

Explanation:

Noble gases have completely filled electronic configuration. Therefore, noble gases or group 18 elements are inert in nature.

Noble gases are 18th group elements in periodic table. They are all having complete filled electronic configuration. The group members are helium, neon, argon, krypton, xenon and radon.

All these elements are existing in gaseous state and they are unreactive. Atoms become reactive when they have extra electrons or are deficient of electrons. Thus to achieve octet, they bond with other atoms.

In the case of noble gases, the valence shell is already achieved octet and no need of lose or gain of electrons. Thus, they are generally inert.

Answer:

4.58g of CO₂ could be produced

Explanation:

Based on the reaction:

C₂H₄(g) + 3O₂(g) → 2CO₂(g) + 2H₂O(g)

1 mole of C₂H₄ reacts with 3 moles of oxygen to produce 2 moles of CO₂

To solve this question we must find the moles of each reactant in order to find limiting reactant. With limiting reactant we can find the moles -And the mass- of CO₂ produced:

Moles C₂H₄ -Molar mass: 28.05g/mol-

2.0g * (1mol / 28.05g) = 0.0713moles

Moles O₂ -Molar mass: 32g/mol-

5.0g * (1mol / 32g) = 0.156moles

For a complete reaction of 0.0713 moles of C2H4 are required:

0.0713 moles C₂H₄ * (3 moles O₂ / 1 mol C₂H₄) = 0.214 moles of O₂

As there are just 0.156 moles, O₂ is limiting reactant.

The moles of CO₂ produced are:

0.156 moles O₂ * (2mol CO₂ / 3mol O₂) = 0.104 moles CO₂

The mass is -Molar mass CO₂: 44.01g/mol-

0.104 moles CO₂ * (44.01g / mol) =

The unknown solution produced a yellow precipitate (3) and did not react with Ba(NO₃)₂. Acidification of the supernate resulted in a white precipitate, confirming the presence of sulfate ions and absence of chloride ions. Iodide (I) and sulfate (SO₄²⁻) are the anions that have been proven to be present in the unknown solution, but chloride (Cl) is not.

Based on the given information, we can determine the anions present and absent in the unknown solution.

Anions present:

1. Iodide (I⁻) - This is confirmed by the formation of a yellow precipitate in aqueous solution.

2. Sulfate (SO₄²⁻) - This is confirmed by the formation of a white precipitate after acidification of the supernate.

Anions absent:

1. Chloride (Cl⁻) - The fact that the supernate did not react with Ba(NO₃)₂ suggests the absence of chloride ions in the unknown solution.

Therefore, the anions confirmed present in the unknown solution are iodide (I⁻) and sulfate (SO₄²⁻), while chloride (Cl⁻) is absent.

The 149.2 grams of potassium chloride would be produced if 78 grams of potassium and 71 grams of chlorine completely reacted.

The balanced chemical equation for the reaction between potassium metal (K) and chlorine gas (Cl₂) to form solid potassium chloride (KCl) is:

2K(s) + Cl₂(g) → 2KCl(s)

This equation indicates that two atoms of potassium react with one molecule of chlorine gas to yield two molecules of potassium chloride.

The type of reaction is a combination reaction, also known as a synthesis reaction. In this type of reaction, two or more substances combine to form a single product.

To determine the mass of potassium chloride produced, we need to calculate the limiting reactant. The molar mass of potassium is approximately 39.1 g/mol, and the molar mass of chlorine is approximately 35.5 g/mol.

First, we convert the given masses of potassium (78 g) and chlorine (71 g) into moles by dividing them by their respective molar masses:

Moles of potassium = 78 g / 39.1 g/mol = 2 mol

Moles of chlorine = 71 g / 35.5 g/mol ≈ 2 mol

Since the reactants have a 1:1 stoichiometric ratio, it can be seen that both potassium and chlorine are present in the same amount. Therefore, the limiting reactant is either potassium or chlorine.

Assuming potassium is the limiting reactant, we can calculate the mass of potassium chloride produced. Since 2 moles of potassium react to form 2 moles of potassium chloride, we can use the molar mass of potassium chloride (74.6 g/mol) to calculate the mass:

Mass of potassium chloride = 2 mol × 74.6 g/mol = 149.2 g

If we compare 1 mole of H₂ , 1 mole of O₂ and 1 mole of F₂, all will have the same number of molecules .

According to Avogadro's law, " Under same conditions of temperature and pressure, equal volumes of different gases will contain equal number of molecules". Mathematically, it is represented as:

V ∝ n

V= nK

where,

v is the volume of the gas

n is the number of moles of the gas

K is the proportionality constant.

The value of Avogadro's constant is 6.022 × 10²³ atoms, ions or molecules

Therefore on the basis of number of molecules:

1 mole of H₂ = 6.022 × 10²³ molecules

1 mole of O₂ =6.022 × 10²³ molecules

1 mole of F₂= 6.022 × 10²³ molecules

The sample of oxygen will occupy approximately 18.5 mL at -70 °C and the same pressure.

The force exerted by a gas on specific area is known as gas pressure..

As we know, (P₁ V₁) /(T₁) = (P₂V₂) /(T₂)

Given, P₁ is the initial pressure (452 torr); V₁ is initial volume (32.2 mL)

T₁ is initial temperature in Kelvin (30 °C + 273.15 = 303.15 K)

P₂ is final pressure (452 torr); V₂ is final volume (what we want to find)

T₂ is the final temperature in Kelvin (-70 °C + 273.15 = 203.15 K)

Now, V2 = (P₁ V₁ T₂) / (P2 T₁)

V₂ = (452 torr x 32.2 mL x 203.15 K) / (452 torr x 303.15 K)

V₂ ≈ 18.5 mL

Therefore, the sample of oxygen will occupy approximately 18.5 mL at -70 °C and the same pressure.
