Temperature and concentration of substrate can alter a protein's shape.

Temperature changes can disrupt the non-covalent interactions that hold a protein's shape together, leading to denaturation or unfolding of the protein. Changes in substrate concentration can also affect a protein's shape by altering the binding interactions between the substrate and the protein.

a protein's shape: temperature, concentration of enzyme, amount of buffer, or concentration of substrate.

The factor that can alter a protein's shape is temperature. Changes in temperature can lead to denaturation, which causes the protein to lose its native conformation and function. This occurs because the heat disrupts the hydrogen bonds and other interactions that maintain the protein's three-dimensional structure.

To recap, temperature can alter a protein's shape by causing denaturation, while the concentration of enzyme, amount of buffer, and concentration of substrate typically do not directly affect the protein's shape.

The correct order of increasing standard molar entropy for the noble gases is: helium (He) < neon (Ne)< argon (Ar)< krypton (Kr)< xenon (Xe)<  radon (Rn)

The correct order of increasing standard molar entropy for the noble gases can be determined by considering their atomic masses and molecular structures. Noble gases are monatomic, which means they consist of individual atoms and not molecules. These gases include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).

Entropy is a measure of the randomness or disorder of a system, and in the case of noble gases, this randomness increases with an increase in atomic mass. The heavier the noble gas, the more complex its atomic structure, leading to higher standard molar entropy values. This is because heavier atoms have more degrees of freedom in motion and energy distribution, contributing to a higher entropy state.

Therefore, the correct order of increasing standard molar entropy for the noble gases is:

He < Ne < Ar < Kr < Xe < Rn

This order starts with helium, which has the lowest atomic mass, and goes up to radon, which has the highest atomic mass among the noble gases. This trend of increasing standard molar entropy is consistent with the atomic mass trend, as heavier noble gases exhibit higher entropy values.

When beaker pressure was lowered then, the glomerular pressure, glomerular filtration rate and the volume of urine was decreased. Option A is correct.

The glomerular filtration rate (GFR) is the rate at which blood is filtered by the kidneys. It depends on several factors, including the glomerular pressure, which is the pressure of blood in the glomerular capillaries of the kidneys.

When the beaker pressure is lowered, it may affect the blood pressure in the kidneys and, therefore, the glomerular pressure. If the glomerular pressure decreases, it may result in a decrease in the GFR, which is the amount of blood filtered by the kidneys per unit time. This may lead to a decrease in urine volume as well, as less fluid is filtered by the kidneys.

Highly reactive electrophilic reagents are needed for reacting with aromatic compounds because of the unique electronic structure of the aromatic ring.

What is Aromatic Compound?

An aromatic compound is a type of organic compound that contains a cyclic arrangement of atoms with alternating double bonds, which is called an aromatic ring or an arene. Aromatic compounds are characterized by their distinctive aroma, from which they derive their name. The most common example of an aromatic compound is benzene, which has a ring of six carbon atoms with alternating double bonds.

The pi electrons in the aromatic ring are delocalized over the entire ring, making it an electron-rich system. This delocalization of electrons creates a region of high electron density around the ring, making it a relatively stable and inert structure. As a result, it is difficult to break into the aromatic ring and react with its carbon atoms.

The volume of acid required to titrate a 20.00 mL sample of base is 20.00 mL, assuming that the concentration of the acid and base is equal.

To determine the volume of acid required to titrate a 20.00 mL sample of base, we need to use the balanced chemical equation and the concept of stoichiometry.

Let's assume that the acid and base react in a 1:1 ratio, which means that one mole of acid reacts with one mole of base.

We are given that the concentration of both acid and base solutions is equal, but we don't know the exact concentration. Therefore, we can represent the concentration of the acid and base as "C."

Reaction between the acid and base can be written as;

acid + base → salt + water

Since we assume that the acid and base react in a 1:1 ratio, we can say that one mole of acid reacts with one mole of base. Therefore, the number of moles of base present in the 20.00 mL sample can be calculated as follows;

moles of base = concentration of base x volume of base

= C x 20.00 mL

= 0.0200 C moles

Since the acid and base react in a 1:1 ratio, the number of moles of acid required to titrate the base is also 0.0200 C moles.

Now, we can use the concentration of the acid to determine the volume of acid required to titrate the base. The number of moles of acid can be calculated as follows;

moles of acid = concentration of acid x volume of acid

We want to find the volume of acid, so we can rearrange the equation as follows;

volume of acid = moles of acid / concentration of acid

= 0.0200 C / C

= 0.0200 L

= 20.00 mL

[tex]N_{t}[/tex]  =  [tex]N_{0}[/tex]  * [tex]1/2^{t/T}[/tex]


We want to find the time t when    [tex]N_{t}[/tex]  = 0.13 * [tex]N_{0}[/tex], or when the amount of U-235 remaining is 13.0% of its initial amount.

0.13 * [tex]N_{0}[/tex] = [tex]N_{0}[/tex]  * [tex]1/2^{t/T}[/tex]

Taking the natural logarithm of both sides, we get:

The numerical value of the rate constant is 2.33 × 10² L²/mol² • s.

The rate law for this reaction can be written as;

rate = k[A]²[B]²

where k is the rate constant.

Using the data provided, we can calculate the rate constant as follows;

For the first set of data;

rate = 4.00 × 10⁻⁵ mol/L • s = k(0.100 M)²(0.100 M)² = k(0.01)²

k = 4.00 × 10⁻⁵ mol/L • s / (0.01)² = 4.00 × 10² L²/mol² • s

For the second set of data;

rate = 4.00 × 10⁻⁵ mol/L • s = k(0.200 M)²(0.100 M)² = k(0.02)²

k = 4.00 × 10⁻⁵ mol/L • s / (0.02)² = 1.00 × 10² L²/mol² • s

For the third set of data;

rate = 8.00 × 10⁻⁵ mol/L • s = k(0.100 M)²(0.200 M)² = k(0.02)²

k = 8.00 × 10⁻⁵ mol/L • s / (0.02)² = 2.00 × 10² L²/mol² • s

To find the average value of k, we can take the average of the three values obtained;

kavg = (4.00 × 10² L²/mol² • s + 1.00 × 10² L²/mol² • s + 2.00 × 10² L²/mol² • s) / 3

This means that the reactions are exothermic, meaning that they release heat, and carbon dioxide is always produced. However, hydrochloric acid doesn't always react readily with solid metal carbonates, so statement III is incorrect.

When hydrochloric acid reacts with a metal carbonate, such as calcium carbonate, the two substances combine to produce calcium chloride, water, and carbon dioxide gas. The reaction is exothermic because it releases heat energy.

The production of carbon dioxide gas is what causes fizzing or bubbling during the reaction. This gas is produced because the hydrochloric acid reacts with the carbonate ion in the metal carbonate, which then produces carbon dioxide gas.

The Ka expression for [tex]HC_4H_7O_2[/tex] is:

[tex]Ka = [H^+][C_4H_7O_2^-] / [HC_4H_7O_2][/tex]

We can use this expression to calculate the concentration of [tex]H^+[/tex] in the solution and then use the pH formula to find the pH. We can assume that the concentration of [tex]HC_4H_7O_2[/tex] is approximately equal to the initial concentration of the solution.

First, we need to calculate the initial concentration of [tex]HC_4H_7O_2[/tex]:

Initial concentration of [tex]HC_4H_7O_2[/tex] = 1.25 mol/L

Next, we can set up an ICE table to determine the concentrations of the species at equilibrium:

Assuming that [tex]x[/tex] is much smaller than 1.25, we can approximate [tex]1.25 - x[/tex] as 1.25:

[tex]1.5 * 10^{-5 }= x^2 / 1.25[/tex]

[tex]x^2 = 1.5 * 10^{-5} * 1.25\\x = \sqrt{1.875 * 10^{-5} \\x = 0.00433 M[/tex]

Therefore, the concentration of [tex]H^+[/tex] is 0.00433 M, and the pH is:

In problem 9, we have the reaction between 1-butene and hydrogen gas in the presence of a palladium catalyst. This reaction can proceed via either a kinetically controlled or thermodynamically controlled pathway.

In the thermodynamically controlled pathway, the more stable product is formed. In this case, the thermodynamic product is 2-butene.

The formation of 2-butene involves the formation of a pi bond between the carbons that were originally connected to the double bond in 1-butene. The hydrogen atom adds to the carbon that was originally connected to the more substituted carbon in 1-butene, resulting in the formation of a secondary carbocation intermediate.

This intermediate then undergoes a 1,2-shift of the alkyl group to form a tertiary carbocation intermediate. The pi bond then forms between the carbons that were originally connected to the double bond in 1-butene, resulting in the formation of 2-butene.

The thermodynamic product is favored over the kinetic product because it is more stable. The double bond in 2-butene is in a more substituted position, resulting in a lower overall energy state. Therefore, the formation of 2-butene is favored over the formation of 1-butene.

Answer:

30  23 45

Explanation:

The total pressure in the flask is 24.91 atm.

To calculate the total pressure in the flask, we need to convert the partial pressures of each gas to the same units, preferably atm.

Partial pressure of nitrogen = 9.65 atm

Partial pressure of oxygen = 631 torr = 0.831 atm (since 1 atm = 760 torr)

Partial pressure of ammonia = 1467 kPa = 14.43 atm (since 1 atm = 101.3 kPa)

Now, we can find the total pressure by adding up the partial pressures of each gas:

Total pressure = 9.65 atm + 0.831 atm + 14.43 atm = 24.91 atm

Therefore, the total pressure in the flask is 24.91 atm.
