The light petroleum product obtained by refining oil is gasoline or petrol. Petroleum or crude oil is a naturally occurring, flammable liquid that consists of a complex mixture of hydrocarbons and other organic compounds. It is extracted from the ground and transported to oil refineries for further processing.

At the refinery, crude oil undergoes a complex series of processes to separate and purify its various components, which are then sold as fuel, lubricants, and other products. Gasoline or petrol is one of the primary products derived from crude oil refining. It is a volatile, flammable liquid that is used as a fuel for internal combustion engines in cars, trucks, motorcycles, and other vehicles. Gasoline is also used as a solvent in industrial processes and as a feedstock for the production of other chemicals and products.

Gasoline is typically produced by a process called fractional distillation, which involves heating crude oil to a high temperature and separating its various components based on their boiling points. During this process, the lighter components of the crude oil, such as gasoline and other hydrocarbons, are separated from the heavier components, such as diesel fuel and lubricating oil. The resulting gasoline is then further refined and blended with other additives to improve its performance and quality.

Gasoline or petrol is the light petroleum product that is obtained by refining oil. It is a vital component of the global economy, as it is used to power transportation and industrial processes around the world. The production of gasoline is a complex and highly regulated process, involving a range of technical and environmental considerations. Despite its many challenges, the refining and production of gasoline remain a critical part of the modern world.

Answer:

Mass = 156.195 g

Explanation:

Given data:

Mass of SO₂ = 125 g

Mass of O₂ = 50.00 g

Mass of SO₃ produced = ?

Solution:

2SO₂ + O₂   →     2SO₃

Number of moles of SO₂:

Number of moles = mass/molar mass

Number of moles = 125 g/ 64.1 g/mol

Number of moles = 1.95 mol

Number of moles of oxygen:

Number of moles = mass/molar mass

Number of moles = 50.00 g/ 32 g/mol

Number of moles = 1.56 mol

Now we will compare the moles of SO₃ with SO₂ and O₂

                         O₂         ;          SO₃

                          1           ;            2

                         1.56      :          2/1×1.56 = 3.12 mol

                      SO₂        ;          SO₃

                          2          ;            2

                         1.95       :          1.95

Less number of moles of SO₃ are produced by SO₂ it will act as limiting reactant:

Mass of SO₃ :

Mass = number of moles × molar mass

Mass =  1.95 mol × 80.1 g/mol

Mass = 156.195 g

Answer:

a) the tendency to form hard, brittle crystals.

Explanation:

Metallic bonding occurs between metals; metals are excellent conductors of electricity, are malleable (can be hammered into thin sheets) and have luster (are shiny). Brittleness is indicative of an ionic bond or ionic compound.

The value of Kc for this reaction is 4.27.

Balanced chemical reaction: Fe³⁺(aq) + 3OH⁻(aq) ⇌ Fe(OH)₃

c(Fe³⁺) = 0.555 M; concentration of iron ions

c(OH⁻) = 0.750 M; concentration of hydroxide ions

m(Fe(OH)₃) = 3.6 g; mass of iron(III) hydroxide

The equilibrium constant (Kc) is a ratio of the concentration of the products  to the concentration of the reactants (in this reaction iron and hydroxide ions). Concentration of the product is 1, because it is in the solid state.

Kc = 1 / c(Fe³⁺) x c(OH⁻)³

Kc = 1 / (0.555 M x (0.750 M)³

Kc = 4.27; equilibrium constant for this reaction.

The change in enthalpy, or heat of vaporization, when 77.2 grams of steam at 100°C is converted to liquid water at the same temperature is approximately 40.7 kJ/mol.

This value represents the amount of energy that must be removed from the steam to condense it into liquid water at 100°C. It is important to note that this value may vary slightly depending on the exact pressure and other conditions of the system.

The change in enthalpy, also known as the enthalpy of vaporization, occurs when steam is converted to liquid water at the same temperature. For this process, 77.2 grams of steam at 100°C is converted to liquid water at 100°C.

To calculate the change in enthalpy, we can use the formula:

ΔH = m × ΔHvap

where ΔH is the change in enthalpy, m is the mass of the steam (77.2 grams), and ΔHvap is the enthalpy of vaporization of water (approximately 40.7 kJ/mol at 100°C).

First, we need to convert the mass of steam to moles using the molar mass of water (18.015 g/mol):

moles of steam = (77.2 g) / (18.015 g/mol) ≈ 4.29 moles

Now we can calculate the change in enthalpy:

ΔH = (4.29 moles) × (40.7 kJ/mol) ≈ 174.6 kJ

So, the change in enthalpy when 77.2 grams of steam at 100°C is converted to liquid water at the same temperature is approximately 174.6 kJ.

The volume occupied at STP by the given mixture of gases is approximately 67.16 L.

To determine the volume occupied by a mixture of gases at STP (Standard Temperature and Pressure), we need to use the ideal gas law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

At STP, the temperature is 273.15 K and the pressure is 1 atm. The ideal gas constant is 0.08206 L·atm/mol·K.

First, we need to find the number of moles of each gas using its mass and molar mass.

For helium (He), the molar mass is 4.00 g/mol, so the number of moles is:

n(He) = 4.00 g / 4.00 g/mol = 1.00 mol

For hydrogen (H2), the molar mass is 2.02 g/mol, so the number of moles is:

n(H2) = 2.00 g / 2.02 g/mol = 0.9901 mol

For oxygen (O2), the molar mass is 32.00 g/mol, so the number of moles is:

n(O2) = 32.0 g / 32.00 g/mol = 1.00 mol

The total number of moles is:

n(total) = n(He) + n(H2) + n(O2) = 1.00 mol + 0.9901 mol + 1.00 mol = 2.9901 mol

Now, we can use the ideal gas law to find the volume of the gas mixture:

V = nRT/P = (2.9901 mol)(0.08206 L·atm/mol·K)(273.15 K)/(1 atm) = 67.16 L

Therefore, the volume occupied at STP by the given mixture of gases is approximately 67.16 L.

The amount of concentrated solution needed is (0.286 M)(65 mL) / C M, and the amount of water needed is 65 mL minus the volume of the concentrated solution.

To calculate the molarity of Kool Aid desired, we need to determine the number of moles of Kool Aid powder and sugar in the package. Since the molecular formula for sugar is C12H22O11, we can calculate its molar mass as follows:

Molar mass of C12H22O11 = (12 * 12.01) + (22 * 1.01) + (11 * 16.00)

= 144.12 + 22.22 + 176.00

= 342.34 g/mol

Given that the package contains 4.25 grams of Kool Aid powder, we can calculate the number of moles of Kool Aid powder using its molar mass:

Number of moles of Kool Aid powder = Mass / Molar mass

= 4.25 g / 342.34 g/mol

≈ 0.0124 mol

Similarly, for the sugar, which has a molar mass of 342.34 g/mol, we can calculate the number of moles of sugar using its mass:

Number of moles of sugar = Mass / Molar mass

= 192.00 g / 342.34 g/mol

≈ 0.5612 mol

Now, to calculate the molarity of the desired Kool Aid solution, we need to determine the volume of water. Given that 1.06 quarts is equal to 1 liter, and we have 2.00 quarts of water, we can convert it to liters as follows:

Volume of water = 2.00 quarts * (1.06 liters / 1 quart)

= 2.12 liters

To find the molarity, we use the formula:

Molarity (M) = Number of moles / Volume (in liters)

Molarity of Kool Aid desired = (0.0124 mol + 0.5612 mol) / 2.12 L

≈ 0.286 M

To prepare 65 mL of the desired molarity, we can use dilution calculations. We need to determine the volume of concentrated solution and the volume of water needed.

Let's assume the concentration of the concentrated Kool Aid solution is C M. Using the dilution formula:

(C1)(V1) = (C2)(V2)where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.

Given that C1 = C M and V1 = V mL, and we want to prepare a final volume of 65 mL (V2 = 65 mL) with a final concentration of 0.286 M (C2 = 0.286 M), we can rearrange the formula to solve for the volume of the concentrated solution:

(C M)(V mL) = (0.286 M)(65 mL)

V mL = (0.286 M)(65 mL) / C M

So, the amount of concentrated solution needed is (0.286 M)(65 mL) / C M, and the amount of water needed is 65 mL minus the volume of the concentrated solution.

The net diffusion of K out of the neuron is reduced when the extracellular K concentration is increased.

Extracellular K ions have a vital role to play in maintaining the correct balance of ions that are present within the neurons. The net diffusion of K out of the neuron is reduced when the extracellular K concentration is increased. It can be explained by the Nernst Equation.

According to the Nernst equation, there is a direct relationship between the ion concentration and the potential across the membrane. If the extracellular K ion concentration is higher, the potential difference required to create an equilibrium state is higher. This is due to the fact that the membrane potential is proportional to the concentration of ions across the membrane.

If the concentration gradient is smaller, the equilibrium potential will be lower, meaning the net diffusion of ions out of the neuron will be reduced.

Therefore, increasing extracellular K will reduce the net diffusion of K out of the neuron.
