suppose you fill the flask with the desired substance then accidentally add distilled water to just above the mark. will the concentration be higher or lower than desired?

According to the law of mass action, the rate of a chemical reaction is directly proportional to the concentrations of the reactants, and inversely proportional to the concentrations of the products.

If the concentration of one or more products is increased, the forward reaction rate will generally decrease because the product molecules are consuming some of the reactants and decreasing the concentration of the reactants available to react. However, increasing the concentration of products can also lead to an increase in the reverse reaction rate, as the excess product molecules increase the likelihood of collisions between the reactant molecules, leading to the formation of more reactants.

Conversely, if the concentration of one or more reactants is decreased, the forward reaction rate will generally decrease because there are fewer reactant molecules available to react. However, decreasing the concentration of reactants can also lead to a decrease in the reverse reaction rate, as the decrease in reactant concentration makes it less likely for reactant molecules to collide and form products.

It is important to note that the specific effects of changes in concentration on reaction rates may vary depending on the particular chemical reaction and the reaction conditions.

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)

= 0.41 V

In this way, the cell potential when 0.5 M Cu(NO3)2 and 1.0 M Pb(NO3)2 are utilized is 0.41 V at 298 K, utilizing the determined E°cell esteem and the Nernst condition.

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.

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)

Moles of oxygen = 2.0 g / 32.00 g/mol = 0.0625 mol

Moles of helium = 98.0 g / 4.00 g/mol = 24.50 mol

Next, we can calculate the mole fraction of oxygen:

Mole fraction of oxygen = moles of oxygen / total moles = 0.0625 mol / (0.0625 mol + 24.50 mol) = 0.0025

We can then use the mole fraction of oxygen and the total pressure of the mixture to calculate the partial pressure of oxygen:

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

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
