The net charge on a molecule of a particular amino acid will be 1- when the pH is higher than the pI (isoelectric point) of the amino acid. In this case, the pI is 7.5, so the net charge will be 1- at a pH higher than 7.5.

The net charge on a molecule of an amino acid depends on the pH of the solution it is in. Amino acids have both acidic and basic functional groups, such as the amino group (-NH2) and the carboxyl group (-COOH). These functional groups can ionize, meaning they can either donate or accept protons depending on the pH of the solution.

The isoelectric point (pI) of an amino acid is the pH at which the net charge on the molecule is zero. At this pH, the number of positive charges (from protonated amino groups) is equal to the number of negative charges (from deprotonated carboxyl groups).

In this case, the pI of the amino acid is 7.5. Since the desired net charge is 1-, the pH must be higher than the pI. At a pH higher than 7.5, the amino acid will have a net negative charge because the carboxyl group will be deprotonated (COO-) while the amino group will remain protonated (NH3+). This results in a net charge of 1- on the molecule.

Objects feels warmer because more light is absorbed

Object appears white because all light is reflected

Object appears black because all light is absorbed

Object feels cooler because less light is absorbed

Reflection of light can affect the color of the material seen in several ways, depending on the properties of the material and the angle of incidence of the light.

When light strikes a surface, some of it is absorbed by the material, while the rest is reflected. The reflected light can be either specular, meaning it reflects at a single angle, or diffuse, meaning it reflects in multiple directions. The color of the material seen depends on the wavelengths of light that are reflected back to the observer.

E = energy of light

h = planck's constant = 6.626*10⁻³⁴J-s

c = speed of light = 3*10⁸ m/s

We are given bond energy of one mole i–i , but we are required to dissociate one molecule of bromine monochloride bond.

The amount of excess acetic anhydride is:Amount of excess acetic anhydride = initial amount - amount used = 0.0196 mol - 0.0145 mol = 0.0051 molTherefore, 0.0051 mol of acetic anhydride is used in the reaction.

The balanced chemical equation for the reaction of salicylic acid with acetic anhydride is given as follows: 2C7H6O3 + C4H6O3 ⟶ 2C9H8O4 + H2OIn this equation, salicylic acid (C7H6O3) is the limiting reagent and acetic anhydride (C4H6O3) is the excess reagent. The stoichiometric ratio between salicylic acid and acetic anhydride is 2:1. This means that for every two moles of salicylic acid, one mole of acetic anhydride is required. To find out how much of the excess reactant is used when the reaction is complete, we need to determine the limiting reagent and the excess reagent. We can do this by calculating the amount of product that each reactant can produce and comparing the values.Let's first calculate the number of moles of each reactant:No. of moles of salicylic acid = mass/molar mass = 2/138 = 0.0145 molNo. of moles of acetic anhydride = mass/molar mass = 2/102 = 0.0196 molTo determine the limiting reagent, we need to calculate the amount of product that each reactant can produce.

According to the balanced equation, 2 moles of salicylic acid produces 2 moles of aspirin, while 1 mole of acetic anhydride produces 2 moles of aspirin. Therefore, the amount of aspirin that can be produced from each reactant is as follows : Amount of aspirin produced from salicylic acid = 2 x 0.0145 mol = 0.0290 molAmount of aspirin produced from acetic anhydride = 2 x 0.0196 mol = 0.0392 molSince salicylic acid can produce only 0.0290 mol of aspirin, it is the limiting reagent. This means that acetic anhydride is in excess. To determine how much of the excess reactant is used, we need to subtract the amount of acetic anhydride used from the amount that was initially present. The amount of acetic anhydride used is equal to the amount of salicylic acid used, which is 0.0145 mol.

Answer and Explanation:

D. I think..

When a weak base is titrated with a strong acid, the equivalence point is: a weak acid's formation.

The equivalence point happens when the moles of the acid equal the moles of the weak base, and pH = 7. It is because the hydronium ion concentration is identical to the hydroxide ion concentration in pure water at this pH. The pH of a weak base solution can be measured during titration.

The reaction between weak bases and strong acids happens in two steps. The first step is the formation of salt through the reaction between acid and base, and the second step is the hydrolysis of this salt. Anions derived from weak bases react with water and accept protons to produce hydroxide ions.

On the other hand, the cations derived from strong acids do not hydrolyze to produce acidic solutions. They can neither react with the acid nor the water, so the only effect is an increase in the concentration of cations in the solution.

The weak base's concentration before and after the equivalence point is much less than the weak acid concentration that is produced at the equivalence point. During the titration, the pH increases slowly initially, but it rises rapidly near the equivalence point, where the weak acid is produced.

After the equivalence point, the pH of the solution is lower because the excess of strong acid has changed the buffer solution into a weak acid solution.

Answer:

4 Sb, 3 \(O_{2}\)

Explanation:

  On the reactant's side of the equation (the left side), there is one Antimony and one Oxygen gas molecule (\(O_{2}\)). The oxygen gas molecule is made of two atoms, so we actually have 2 oxygens on the left side. On the product's side (the right side), there are 4 antimony atoms, and 6 oxygen atoms. If we were to write it out in a certain way, it would look like this:

__Sb + __ \(O_{2}\) --> \(Sb_{4} O_{6}\)

                  1   Sb   4

                  2   O   6

  To balance this equation, those numbers on either side of the elements must equal each other. We can accomplish this with the proper coefficients. If we put a 4 in front of the antimony, it means this:

4 Sb + __ \(O_{2}\) --> \(Sb_{4} O_{6}\)

                  4   Sb   4

                  2   O   6

And the antimony is now balanced.

  Now we must balance the oxygen. There are 6 oxygens on the product's side but only 2 on the reactant's side. To fix this, simply multiply the oxygen by 3:

4 Sb + 3 \(O_{2}\) --> \(Sb_{4} O_{6}\)

              4   Sb   4

              6   O   6

3 * 2 = 6, so now oxygen is balanced, and the equation is now correct.

The correct answer is C) —COO− + —NH2+ → —COOH + —NH2. This is because pK2 refers to the second dissociation constant of the amino acid valine, which is the dissociation of the carboxyl group (—COOH) from the amino group (—NH2+).

During titration with a strong base like NaOH, the base will react with the acidic proton (H+) on the carboxyl group, resulting in the formation of the carboxylate ion (—COO−) and water (H2O). However, once all the carboxyl groups have been neutralized, the excess base will react with the amino group (—NH2+) and remove the proton (H+) from it, resulting in the formation of the amino ion (—NH2) and water (H2O). This is the point at which pK2 is reached, and the reaction is represented by the equation C) —COO− + —NH2+ → —COOH + —NH2. The other answer choices are not relevant to the titration of valine with a strong base.

Explanation:

One of the characteristics of gases is that gases are highly compressible. The correct option is C.

Gases possess several characteristic properties that distinguish them from other states of matter such as solids and liquids. The key properties of gases are as follows:

1. Expansion: Gases have the ability to expand and fill the entire available space of a container. They lack a definite shape or volume, and their particles are widely spaced.

2. Compressibility: Gases are highly compressible compared to solids and liquids. Under increased pressure, the volume of a gas decreases significantly, allowing it to be compressed into a smaller space.

3. Fluidity: Gases flow readily and can be easily poured or transferred from one container to another. They do not exhibit any resistance to shear forces and can easily mix with other gases.

4. Low Density: Gases have a low density compared to solids and liquids. The particles in a gas are far apart, resulting in a low mass per unit volume.

5. Diffusion and Effusion: Gaseous particles are in constant random motion and undergo diffusion, spreading out and mixing with other gases. They also exhibit effusion, which refers to the escape of gas molecules through tiny openings or pores.

6. High Kinetic Energy: Gas molecules possess high kinetic energy and move rapidly in all directions. The average speed of gas particles increases with higher temperatures.

7. Pressure: Gases exert pressure on the walls of their container due to the collisions between the gas particles and the container. The pressure of a gas is directly proportional to its temperature and the number of gas particles.

These properties collectively characterize gases and are a result of the weak forces of attraction between gas particles, allowing them to move freely and independently.

The correct option is C) Gases are highly compressible.
