Because of the existence of resonance, the conjugate base is stabilized, making it a weaker base. We infer that the amide is a stronger acid than the amine because a weaker conjugate base is formed from a stronger acid. +) has a lower acidity than the hydronium ion (H3O+).

When the negative charge occurs on an electronegative element and is delocalized over several atoms, a conjugate base is more stable. The stronger the acid, the more stable the conjugate base.

A conjugate acid-base pair, according to the Brnsted-Lowry definition of acids and bases, consists of two compounds that vary solely by the presence of a proton (H+). When a proton is added to a base, a conjugate acid is created, and when a proton is added to a base, a conjugate base is formed.

To prepare a buffer solution with a pH of 5.59 (with a pKa of 4.54), we need to add 0.134 mL of 0.1 M NaOH to 24.0 mL of 0.1 M HB.

The pH of a buffer answer is without delay associated with its pKa value. The pKa of a buffer answer is the pH at which the ratio of the conjugate base (B-) to its corresponding acid (HB) is equal to one. At this point, the buffer is handiest at resisting adjustments in pH when small amounts of acid or base are introduced. The closer the pH of the buffer solution is to its pKa value, the extra effective the buffer might be at resisting adjustments in pH. Because of this if the pH of the buffer solution is equal to its pKa, the buffer will be at its maximum buffering potential.

The intermolecular forces that contribute to creating a solution of CH2Cl2 in H20 are London Dispersion, lon-dipole, dipole-dipole, and H-bonding forces.

Intermolecular forces are the forces of attraction or repulsion that exist between molecules. These forces determine the physical and chemical properties of a substance, such as boiling point, melting point, and viscosity.

The most common intermolecular forces are London dispersion forces, dipole-dipole forces, and hydrogen bonding. London dispersion forces are weak forces that arise from the temporary movement of electrons in a molecule, and can be found in all molecules. Dipole-dipole forces occur between molecules with permanent dipoles, and cause them to be attracted to one another. Hydrogen bonding is a special type of dipole-dipole force that occurs when a hydrogen atom is covalently bonded to an electronegative atom such as oxygen or nitrogen. This type of bond is especially strong, and is responsible for the high boiling and melting points of some substances.

The energy diagram contains two maxima, which indicates that the reaction contains two elementary steps. The first maximum corresponds to the transition state of the first step and the second maximum corresponds to the transition state of the second step. The activation energy of the first step is less than the activation energy of the second step, meaning the first step proceeds at a faster rate than the second step. Therefore, the most probable reaction mechanism is

2A−→−fastB

B−→−−slowC

Explanation:

Answer:

A+B−→−−slowC

C−→−fastD

The energy diagram contains two maxima, which indicates that the reaction contains two elementary steps. The first maximum corresponds to the transition state of the first step and the second maximum corresponds to the transition state of the second step. The activation energy of the first step is greater than the activation energy of the second step, meaning the first step proceeds at a slower rate than the second step.

Taking into account the definition of calorimetry, the energy released when 240 g of iron is cooled by 65 °C is 7051.2 J.

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

When heat added or removed from a substance causes a temperature change in it without affecting its molecular structure, it is called sensible heat.

The expression that allows to calculate heat exchanges is:

Q = c× m× ΔT

where:

In this case, you know:

Replacing in the definition of calorimetry:

Q = 0.452 J/g°C× 240 g× 65°C

Answer: A

Explanation:  Electronegativities are used to determine the polarity of covalent bonds.

The volume of CO2 produced at STP from the combustion of 10.50 L of C2H6 (measured at 27°C and 778 torr) is 5.32 L.

The volume of carbon dioxide produced from the combustion of a given amount of ethane gas can be determined using the ideal gas law and stoichiometry. This calculation takes into account the temperature, pressure, and volume of the reactants and products, and the balanced chemical equation for the reaction.

To find the volume of CO2 produced from the combustion of 10.50 L of C2H6 (measured at 27°C and 778 torr), we can use the ideal gas law, PV = nRT, where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in kelvins.

First, we need to convert the temperature to kelvins: T = 27°C + 273 = 300 K. Next, we need to find the number of moles of C2H6. We can use the volume of the gas and the pressure to find the number of moles: n = (PV)/(RT) = (778 * 10.50 L)/(0.0821 Latm/K * 300 K) = 0.367 moles.

Next, we need to use the balanced chemical equation to find the number of moles of CO2 produced: 4 moles CO2 are produced for every 2 moles of C2H6. Thus, 0.367 moles of C2H6 produces 0.367 * 2/4 = 0.184 moles of CO2.

Finally, we can use the ideal gas law to find the volume of CO2 produced at STP (standard temperature and pressure, which is 0°C and 1 atm): V = (nRT)/P = (0.184 moles * 0.0821 Latm/K * 273 K) / 1 atm = 5.32 L.

When naming an ionic compound, the cation is stated first, then the anion. Charges that are positive and negative must be equal. Roman numerals are used in parenthesis to name some anions that have several forms.

Three or more elements make up ternary compounds. It is analogous to naming basic ionic compounds to name binary (two-element) molecular molecules. The first component of the formula is only the element's name mentioned. By taking the element name's stem and adding the suffix -ide, the second element is given a name.

The basic rule is that a bond is termed nonpolar if the difference in electronegativities is less than or equal to roughly 0.4; if the difference is larger than 0.4, the bond is considered polar.

The solution does not change color with the addition of diethyl carbonate in a crystal violet reaction because it does not interfere with the dye-base interaction.

In a crystal violet reaction, the dye crystal violet is dissolved in an acidic solution, where it exists as an ionized species. The addition of a basic compound, such as diethyl carbonate, can alter the pH of the solution and affect the ionization of the dye, potentially changing its color.

However, diethyl carbonate is a weak base that does not interfere with the dye-base interaction and therefore does not alter the color of the solution. This makes it useful as a solvent for crystal violet and other dyes, as it allows the color to be measured without interference from the solvent.

The pH falls as the hydrogen ion concentration rises.

Seven is the neutral pH. An increase in pH above 7 indicates an increase in alkalinity, whereas a fall in pH below 7 indicates an increase in acidity (hydrogen ions) (hydroxyl ions). Each pH unit corresponds to a concentration change of 10 times. The amount of hydronium in the solution rises as H+ ions separate from the acid and unite with water to create hydronium ions. A solution becomes less acidic and more basic as the hydronium concentration declines and the pH rises. We refer to a neutral solution with [H+]=10-7 as having a pH of 7. For instance, this indicates that a solution with a pH of 4 has a hydrogen-ion concentration of 10-4mol/l, or 0.0001 mol of hydrogen ions per liter of the solution.

The hydrogen ion concentration's negative log is known as pH. pH1 is the acidic range. Highest on the scale and very basic is pH 14. However, by comparing two H+ concentrations, we may observe what is taking place:

Since the log of [H+] = 1x10-10 is -10 and there is a negative sign to make it positive, the pH at this concentration is 10.

The pH is -log(10-2), or 2, at larger concentrations, such as 1x10-2 or more. [H3O+] = 10-pH So for pH = 11 , [H3O+] = 10-11 M ,and for pH = 8  , [H3O+] = 10-8.
