Using Boyle's law, If pressure is increased to 3.25 atm, then the gas occupy volume will decrease from 248 mL to 76. 308 mL. So, option( b) is right answer.

Boyle's Law : It is states as the pressure on a gas increases, the volume of the gas decreases because the gas particles are forced closer together. Mathematically, at constant temperature, P₁ V₁ = ₂V₂

where, P₁ --> initial pressure

P₂ ---> final pressure

V₁ --> initial volume

V₂ --> final volume

The occupy volume of a gas, V = 248 mL

Pressure, P = 1.00 atm

If the pressure is increased to 3.25 atm, then we will determine the volume of gas. Using the Boyle's law equation, P₁ V₁ = P₂ V₂

here, P₁= 1 atm , P₂ = 3.25 atm, V₁ = 248 mL

Substitute all known values in above formula,

=> 1 atm × 248 mL = 3.25 atm × V₂

=> V= 248/3.25 mL = 76. 308 mL

Hence, required value is 76. 308 mL.

In a reaction between an acid chloride and a primary alkyl chloride with a nucleophile, the acid chloride is generally more reactive than the primary alkyl chloride due to the presence of the electron-withdrawing carbonyl group in the acid chloride.

For example, if we react an acid chloride like acetyl chloride (CH3COCl) with a nucleophile like water (H2O), we get the following reaction:

CH3COCl + H2O → CH3COOH + HCl

In this reaction, the acetyl chloride reacts with water to form acetic acid (CH3COOH) and hydrochloric acid (HCl) as a byproduct. This reaction is an example of an acyl substitution reaction, where the nucleophile (water) substitutes the leaving group (chloride) on the acid chloride.

On the other hand, if we react a primary alkyl chloride like ethyl chloride (CH3CH2Cl) with water (H2O), we get the following reaction:

CH3CH2Cl + H2O → CH3CH2OH + HCl

In this reaction, the ethyl chloride reacts with water to form ethanol (CH3CH2OH) and hydrochloric acid (HCl) as a byproduct. This reaction is an example of a nucleophilic substitution reaction, where the nucleophile (water) substitutes the leaving group (chloride) on the primary alkyl chloride.

The rate of reaction for the acyl substitution reaction with the acid chloride is generally faster than the rate of reaction for the nucleophilic substitution reaction with the primary alkyl chloride, indicating the greater reactivity of the acid chloride.

The pH of the buffer solution after the addition of 0.01 mol of NaOH is approximately 4.78.

To find the pH of the buffer solution after the addition of 0.01 mol of NaOH, we'll need to use the Henderson-Hasselbalch equation and consider the reaction between the base (NaOH) and the weak acid (propionic acid, HC₃H₅O₂).

1. Write the reaction between NaOH and HC₃H₅O₂:
NaOH + HC₃H₅O₂ -> NaC₃H₅O₂ + H2O

2. Determine the initial concentrations of the weak acid and its conjugate base:
[HC₃H₅O₂] = 0.15 mol / 1.20 L = 0.125 M
[NaC₃H₅O₂] = 0.10 mol / 1.20 L = 0.0833 M

3. Calculate the change in concentrations after the reaction with NaOH:
0.01 mol of NaOH will react with 0.01 mol of HC₃H₅O₂, decreasing its concentration by 0.01 mol and increasing the concentration of NaC3H5O2 by the same amount:
[HC₃H₅O₂] final = 0.125 M - 0.01 mol/L = 0.115 M
[NaC₃H₅O₂] final = 0.0833 M + 0.01 mol/L = 0.0933 M

4. Use the Henderson-Hasselbalch equation to find the pH:
pH = pKa + log([A-]/[HA])
The pKa of propionic acid is 4.88.
pH = 4.88 + log(0.0933 M / 0.115 M)

5. Calculate the pH:
pH ≈ 4.88 - 0.10 = 4.78

If you mix a solution containing 1.98 moles of solute with another solution containing 4.2 moles of solute, the resulting solution would have a total of 6.18 moles of solute and, assuming ideal behavior and STP conditions.

Molarity (M), which is determined by dividing the solute's mass in moles by the volume of the solution in litres, unit of measurement most frequently used to express solution concentration.

The following procedures can be used to estimate the total volume of the resultant solution using the ideal gas law, assuming that the two solutes are acting optimally:

Count the total moles of solute there are in the solution.

Total moles of solute = 1.98 moles + 4.2 moles = 6.18 moles

Convert the total number of moles to volume using the ideal gas law:

V = (nRT) / P

Assuming standard temperature and pressure (STP), which is 0°C (273.15 K) and 1 atm, respectively, you can calculate the volume as follows:

Answer:

To calculate the specific heat of the rock, you can use the formula for heat transfer: Q = mcΔT, where Q is the heat transferred, m is the mass of the substance, c is the specific heat capacity and ΔT is the change in temperature.

In this case, we can assume that the heat lost by the rock is equal to the heat gained by the water. Therefore:

Q(rock) = Q(water)

m(rock)c(rock)(T(final) - T(initial, rock)) = m(water)c(water)(T(final) - T(initial, water))

where m(rock) = 6.7 g, T(initial, rock) = 100.0°C, T(final) = 45°C, m(water) = 100.0 g (assuming the density of water is 1 g/mL), c(water) = 4.18 J/g°C (specific heat capacity of water), and T(initial, water) = 23°C.

Substituting these values into the equation above and solving for c(rock), we get:

c(rock) = (m(water)c(water)(T(final) - T(initial, water))) / (m(rock)(T(final) - T(initial, rock)))

c(rock) = (100.0 g * 4.18 J/g°C * (45°C - 23°C)) / (6.7 g * (45°C - 100.0°C))

c(rock) ≈ 1.26 J/g°C

So the specific heat of the rock is approximately 1.26 J/g°C.

The volume of the gas at 175.0°C would be approximately 24.48 L.

To determine the volume of a gas at a different temperature using the ideal gas law, we can use the following formula:

V1 / T1 = V2 / T2

where:

V1 = Initial volume of the gas

T1 = Initial temperature of the gas

V2 = Final volume of the gas (which we want to find)

T2 = Final temperature of the gas (given in the question)

Given values:

V1 = 16.00 L

T1 = 20°C = 20 + 273.15 K (converting Celsius to Kelvin)

T2 = 175.0°C = 175 + 273.15 K (converting Celsius to Kelvin)

Plugging in the values into the formula:

16.00 L / (20 + 273.15 K) = V2 / (175 + 273.15 K)

Solving for V2, we get:

V2 = 16.00 L * (175 + 273.15 K) / (20 + 273.15 K)

Calculating the right-hand side of the equation:

V2 = 16.00 L * 448.15 K / 293.15 K

The cell capability of a galvanic cell can be resolved utilizing the Nernst condition, which relates the standard cell potential, the response remainder, and the groupings of the species in question.

For this situation, the fair condition for the response is:

Cu2+(aq) + Pb(s) → Cu(s) + Pb2+(aq)

Involving the standard decrease possibilities for every half-response, the standard cell potential, E°cell, can be determined as:

E°cell = E°(reduction at cathode) - E°(reduction at anode)

= E°(Cu2+(aq) + 2e-→ Cu(s)) - E°(Pb2+(aq) + 2e-→ Pb(s))

= +0.34 V - (- 0.13 V)

= +0.47 V

The response remainder, Q, can be determined utilizing the groupings of the species in question:

Q = [Cu2+][Pb2+]/[Cu][Pb]

= (0.5 M)(1.0 M)/(1.0 M)(1.0 M)

= 0.50

At 298 K, the Nernst condition can be composed as:

Ecell = E°cell - (RT/nF)lnQ

where R is the gas steady, T is the temperature in kelvins, n is the quantity of electrons moved in the response, F is the Faraday consistent, and ln is the normal logarithm. Subbing the qualities determined over, the cell potential can be determined as:

Ecell = 0.47 V - [(8.314 J/(mol K))(298 K)/(2 mol e-/F)]ln(0.50)

The pH of a 1 x 10^5 M KOH solution is 5.0.

pH is a measure of the acidity or basicity (alkalinity) of a solution. It is defined as the negative logarithm (base 10) of the concentration of hydrogen ions (H+) in a solution:

pH = -log[H+]

A pH value of 7 is considered neutral, meaning that the concentration of hydrogen ions and hydroxide ions in the solution is equal (10^-7 M). A pH value below 7 indicates an acidic solution, meaning that the concentration of hydrogen ions is higher than the concentration of hydroxide ions. A pH value above 7 indicates a basic (or alkaline) solution, meaning that the concentration of hydroxide ions is higher than the concentration of hydrogen ions.

The pH of a solution can be calculated using the formula:

pH = -log[H+]

where [H+] is the concentration of hydrogen ions in the solution.

For a strong base like KOH, we can assume that it completely dissociates in water, producing equal amounts of hydroxide ions (OH-) and potassium ions (K+). Therefore, the concentration of hydroxide ions in a 1 x 10^5 M KOH solution is also 1 x 10^5 M.

Using the formula above, we can calculate the pH of the solution as:

pH = -log(1 x 10^-5)

The gravitational potential energy (GPE) of a 1 kg fish positioned 0.5 meters above the ground is 4.9 joules (J).

What is Gravity?

Gravity is a fundamental force of nature that causes objects with mass or energy to be attracted to one another. It is the force that gives weight to physical objects and determines how objects interact with each other due to their mass. Gravity is responsible for the motion of celestial bodies, such as planets, stars, and galaxies, and it plays a crucial role in the structure and evolution of the universe.

GPE = mgh

where:

Given the information provided:

Mass of the fish (m) = 1 kg

Height above ground (h) = 0.5 meters

Acceleration due to gravity (g) = 9.8 m/[tex]s^{2}[/tex]

Plugging these values into the formula, we get:

GPE = (1 kg) x (9.8 m/[tex]s^{2}[/tex]) x (0.5 m)

GPE = 4.9 J

Answer:

data given

volume 1.5l

molarity2.5

Required mass to be added

Explanation:

from

molarity =mass/molar mass ×volume

3.1=m/58.5×1.5

m=272g

also,

2.5=m/58.5×1.5

m=219.38

now,

mass increased =272-219.38

m=52.62

: . mass increased is 52 62g
