When two atoms are being held together by an ionic bond, which of the following statements is accurate?

a. Each of the two atoms had a full outer orbital before the bond occurred.
b. The two atoms share an electron.
c. One atom is now positively charged and the other is negatively charged.
d. The two atoms have identical atomic numbers.

Answers

Correct option is c) One atom is now positively charged, and the other is negatively charged. This is due to nature of ionic bond.

An ionic bond is formed when one or more electrons are transferred from one atom to another, resulting in the formation of two oppositely charged ions. In an ionic bond, the electron(s) transferred from one atom are accepted by the other atom, leading to the formation of cations and anions.

The atom that loses an electron becomes a positively charged ion (cation), and the atom that gains an electron becomes a negatively charged ion (anion). The opposite charges of the ions attract each other and form an ionic bond between the two atoms.

Ionic bonds usually occur between atoms of different elements with a significant difference in electronegativity. Ionic compounds generally have high melting and boiling points, are solid at room temperature, and are usually soluble in water.

In contrast to an ionic bond, a covalent bond is formed when atoms share electrons, as in the case of molecular compounds. In a covalent bond, atoms do not become charged. Instead, they share electrons in a way that allows them to complete their valence shells.

Which answer below correctly identifies the type of change and the explanation when potassium iodide and lead nitrate are mixed?

physical change because the observation of a solid forming is evidence of a state change, which is reversible

physical change because even though the mixture had a color that was different from either of the two solids alone, each solid's physical properties remained exactly the same

chemical change because two substances were mixed, which always results in the formation of a
new substance

chemical change because both a color change and a solid formation were observed, which provide strong evidence of a new substance

Answers

Answer:

The correct answer is chemical change because both a color change and a solid formation were observed, which provide strong evidence of a new substance.

A physical change is a change in the state of a substance, such as a change from a solid to a liquid or a change from a liquid to a gas. A chemical change is a change in the composition of a substance, such as the formation of a new substance.

When potassium iodide and lead nitrate are mixed, a yellow precipitate forms. This precipitate is a new substance that was not present before the two substances were mixed. Therefore, the change that occurs when potassium iodide and lead nitrate are mixed is a chemical change.

The other answers are incorrect.

* Answer 1 is incorrect because the observation of a solid forming is not evidence of a state change. A state change is a change in the physical state of a substance, such as a change from a solid to a liquid or a change from a liquid to a gas. The formation of a precipitate is not a state change, but rather a chemical change.

* Answer 2 is incorrect because the color change of the mixture is evidence of a chemical change. When two substances are mixed and a new substance is formed, the new substance may have a different color than the original substances.

* Answer 3 is incorrect because the statement "two substances were mixed, which always results in the formation of a new substance" is not always true. For example, if you mix two different types of liquids, you may not get a new substance. Instead, you may just get a mixture of the two liquids.

Final answer:

The reaction between potassium iodide and lead nitrate results in a chemical change because a color change and solid formation, indicative of a new substance, are observed.

Explanation:

When potassium iodide and lead nitrate are mixed, there is a chemical change that takes place. This is because both a color change and a solid formation were observed, which provide strong evidence of a new substance. In this reaction, two new compounds are formed - lead iodide and potassium nitrate - which is a clear indication of a chemical change. This process is not easily reversible, further supporting it being a chemical change.

A chemist titrates 150.0 mL of a 0.8748M benzoic acid (HC,H,CO₂) solution with 0.3544M KOH solution at 25 °C. Calculate the pH at equivalence. The pK,
of benzoic acid is 4.20.
Round your answer to 2 decimal places.

Answers

The balanced chemical equation for the reaction between benzoic acid and potassium hydroxide is:

HC7H5O2(aq) + KOH(aq) → KC7H5O2(aq) + H2O(l)

The number of moles of benzoic acid used in the titration is:

n(HC7H5O2) = M × V = 0.8748 mol/L × 150.0 mL / 1000 mL/L = 0.13122 mol

The volume of KOH solution required to reach equivalence point can be determined using the stoichiometry of the balanced equation. The stoichiometric ratio of benzoic acid to potassium hydroxide is 1:1. Therefore, the number of moles of KOH required to neutralize all of the benzoic acid is equal to n(HC7H5O2):

n(KOH) = 0.13122 mol

The volume of KOH solution required can be calculated as:

V(KOH) = n(KOH) / M(KOH) = 0.13122 mol / 0.3544 mol/L = 0.3701 L

At equivalence, the total volume of the solution is:

V(total) = V(HC7H5O2) + V(KOH) = 0.1500 L + 0.3701 L = 0.5201 L

The concentration of the salt formed, KC7H5O2, is:

M(KC7H5O2) = n(KC7H5O2) / V(total) = n(HC7H5O2) / V(total) = 0.13122 mol / 0.5201 L = 0.2523 M

The pH at equivalence can now be calculated using the acid dissociation constant (Ka) of benzoic acid:

Ka = [H+][C7H5O2-] / [HC7H5O2]

pKa = -log(Ka) = -log(6.3 × 10^-5) = 4.20

At equivalence, the concentration of benzoic acid and benzoate ions are equal, so [HC7H5O2] = [C7H5O2-]. Let x be the concentration of H+ ions at equivalence. Then:

Ka = x^2 / (0.2523 - x)

Solving this equation for x gives:

x = sqrt(Ka × (0.2523 - x)) = sqrt(6.3 × 10^-5 × 0.2523) = 0.002532

Therefore, the pH at equivalence is:

pH = -log[H+] = -log(0.002532) = 2.60

Rounding to two decimal places, the pH at equivalence is 2.60.

Which is the order from fastest to slowest for the rates of the SN2 reactions of these alkyl bromides with CH3S-/DMSO?
a. 1>2>3
b. 3>1>2
c. 2>3>1
d. 1>3>2

Answers

The order from fastest to slowest for the rates of the SN2 reactions of these alkyl bromides with CH3S-/DMSO is 2>3>1. Option C.

Primary alkyl halides undergo SN2 reactions faster than secondary and tertiary ones. Compound IV reacts faster in the SN1 reaction than in the SN2 reaction. This is due to the steric hindrance and difficult access of the nucleophile from the side opposite the leaving group.

The rate-limiting step in the reaction is the attack of the nucleophile on the substrate. Therefore, SN2 is easier to run against stronger nucleophiles. Since there are two molecules in the transition state, the reaction is a bimolecular reaction, indicated by the number 2 in the SN2 symbol. The kinetics of the SN2 reaction is first order within the substrate and first order within the nucleophile.

How many formula units are in 50.0g of Pb02?

Answers

There are approximately \(1.258 x 10^2^3\) formula units in 50.0 g of PbO2.

To solve this problem

We must utilize the molar mass of PbO2 (lead dioxide) and the idea of Avogadro's number to calculate the number of formula units in a given mass of PbO2.

The molar mass of PbO2 is calculated as follows:

1 atom of Pb (lead) has a molar mass of approximately 207.2 g/mol.

2 atoms of O (oxygen) have a combined molar mass of approximately 32.0 g/mol (16.0 g/mol per oxygen atom).

Therefore, the molar mass of PbO2 is:

Molar mass of PbO2 = (1 * molar mass of Pb) + (2 * molar mass of O)

= (1 * 207.2 g/mol) + (2 * 16.0 g/mol)

= 207.2 g/mol + 32.0 g/mol

= 239.2 g/mol

Now, we can use the molar mass to determine the number of formula units in 50.0 g of PbO2.

Number of moles = Mass (in grams) / Molar mass

= 50.0 g / 239.2 g/mol

≈ 0.209 moles (rounded to three decimal places)

Since 1 mole of any substance contains Avogadro's number of particles \((approximately 6.022 x 10^2^3),\)we can calculate the number of formula units by multiplying the number of moles by Avogadro's number:

Number of formula units = Number of moles * Avogadro's number

\(= 0.209 moles * (6.022 x 10^2^3 formula units/mole)\)

≈\(1.258 x 10^2^3 formula units\)

Therefore, there are approximately\(1.258 x 10^2^3\) formula units in 50.0 g of PbO2.

Please if the answer is correct, ill give brainliest

Answers

250 L of 5.0% w/v glucose solution can be prepared using 125 g of glucose.

We use the below formula to solve our problem,

w/v = [ mass of solute (g) / volume of solution (mL) ] × 100

Substitute the values from our problem,

5.0 % w/v = [ 125 g / volume of solution (mL) ] × 100

Rearranging the formula, we have

volume of solution (mL) = [ 125 g / 5.0 % w/v ] x 100

Substitute further for w/v,

volume of solution (mL) = [ 125 g / (5.0 / 100) ] x 100

Simplify the expression,

volume of solution (mL) = [ 125 g / 0.05 ] x 100

Hence, the volume of solution (mL) = 250,000 mL or 250 L

Why does the solubility of many substances increase with temperature? (Remember what an increase in temperature means on a microscopic scale.)

Answers

The solubility of many substances increases with temperature, there are exceptions. Some substances exhibit a decrease in solubility with temperature due to specific interactions or changes in solute-solvent interactions at higher temperatures.

The increase in solubility of many substances with temperature can be attributed to the effect of temperature on the kinetic energy and intermolecular interactions of molecules.

On a microscopic scale, an increase in temperature corresponds to an increase in the kinetic energy of molecules. As the kinetic energy increases, the molecules move more rapidly and collide with each other and with the solvent molecules more frequently and with greater force.

These increased collisions and kinetic energy result in enhanced molecular interactions and overcome the forces holding the solute particles together. This increased energy disrupts the intermolecular forces within the solute, allowing the solvent molecules to surround and interact more effectively with the solute particles, leading to greater solubility.

Additionally, an increase in temperature can cause solvent molecules to move more freely, reducing their cohesion and allowing them to interact more readily with solute particles.
