what kind of intermolecular forces act between a chloramine (nh2cl) molecule and a potassium cation?

Answers

Answer 1

The intermolecular forces act between a chloramine (nh2cl) molecule and a potassium cation is Dipole to Dipole bonding.

What is an example of a dipole-dipole interaction?

A dipole-dipole interaction can occur between polar molecules such as hydrogen chloride (HCl), carboxylic acids (i.e., acetic acid), and amino acids. The positive end of a polar molecule will attract the negative end of the other molecule and alter its location.

What is  Dipole to Dipole bonding?

Dipole to Dipole force arise when atoms with partial charges within a molecule attract another atom with an opposite partial charge that is located around the molecule.

Therefore,

Because chloroamine and water are both polar solvents, hydrogen bonds, dispersion forces, and dipole-dipole forces of attration exist between them. Water molecules form hydrogen bonds.

Hence Dipole to Dipole bonding is a correct answer.

consider the reaction. 2pb(s) o2(g)⟶2pbo(s) an excess of oxygen reacts with 451.4 g of lead, forming 349.3 g of lead(ii) oxide. calculate the percent yield of the reaction.

Answers

The percent yield of the reaction is 77.1% while forming lead oxide.

What is atomic mass?

The atomic mass of a chemical element, expressed in atomic mass units. This roughly corresponds to the number of protons and neutrons in the atom (mass number), or the average number taking into account the relative abundance of different isotopes.

To calculate the percent yield, we need to determine the theoretical yield of the reaction. The theoretical yield is the amount of product that would be produced if all of the reactants were consumed in the reaction. We can do this by using the stoichiometric coefficients of the reactants and products. In this case, 2 moles of lead react with 1 mole of oxygen to produce 2 moles of lead(II) oxide.

How to calculate percent yield?

Since we have 451.4 g of lead, that's equivalent to 0.799 moles of lead. From the stoichiometric equation,

We can determine that this would produce 0.799 moles of lead(II) oxide, which is equal to 349.3 g.

The percent yield is calculated by dividing the actual yield (349.3 g) by the theoretical yield (349.3 g) and multiplying by 100.

Step 1: Generate moles from 12g of phosphorus

30.97 grams of P divided by 12 grams of P gives you 0.39 moles of P.

Step 2: Using the formula: 0.39 moles of P * (3 moles of Cl2/2 moles of P) *(70.90 grams of Cl2/1 mol of Cl2) = 41.48 grams of Cl2

Since chlorine gas' supply depletes more quickly, it can be assumed that chlorine gas is the limiting reactant in this situation. Therefore, the theoretical yield of PCl3 produced should be calculated using chlorine gas.

Step 3: Calculate the moles of 35.5 grams of Cl2

0.501 moles of Cl2 are equal to 35.5 grams of Cl2*(1 mol of Cl2/70.90 grams of Cl2).

Step 4: Predict the amount of PCl3 created using mole ratios.

Therefore, the percent yield of the reaction is 77.1%.

The concentration is 1.66x10-24 M if there is exactly one molecule of the solute in one litre of solution.

In this situation, 1 mole is defined as 6.02x10²³ particles, or molecules. As a conversion factor, consider the following:

1 mole = 6.02 x 10²³ molecules.

When only 1 molecule of the solute is present, use this conversion factor to determine moles of the solute:

1.66x10-24 moles are equal to (1 molecule)/((1 mole)/(6.02x1023 molecules)).

Only moles remain after the molecules cancel.

By definition, concentration is the number of moles of a solute per litre. Divide the volume, in this case 1.0L, by the 1.66x10-24 moles to get:

Definition of Chemical reaction

Chemical reactions happen absolutely everywhere in our daily life. While we sometimes associate chemical reactions with only the sterile environment of test tubes and laboratories, nothing is farther from the truth. In fact, a wide range of transformations are creating a dizzying and almost incomprehensible series of new matter and energy changes in our world every second of every day.

Moles KO₂ = 2.41g/(71.1g/mole) = 0.034 moles

Moles CO₂ = 4.62g/(44g/mole) = 0.105 moles

4KO₂ + 2CO₂ → 2K₂CO₃ + 3O₂

The reaction requires twice as many moles of KO₂ than moles of CO₂.  That means 0.105 mole of CO₂ would consume 0.034 moles of KO₂.  But there is only have 0.034 moles of KO₂, so the limiting reagent is KO₂.  

There are 3 moles of O₂ produced for every 2 moles of CO₂ consumed.  In this case we'll assume all of the KO₂ reacts, so that should result in (3/4) × (0.034moles) = 0.025 moles of O₂ .

To get the mass, 0.025 mole × (32g/mole) = 0.823 grams O₂

suppose both the electron affinity of and the heat of sublimation of were smaller. would be more stable? or less?

Answers

If both electron affinity and heat of sublimation are smaller, then MX would be less stable.

M²⁺ + X⁻(g) → MX(s), + Lattice energy

Therefore, from the given thermodynamic cycle,

Lattice enthalpy = -100-800 = -900kJ/mol

Lattice enthalpy MX = -900kJ/mol

Enthalpy of the formation of MX is given as follows:

M(s) + 1/2X₂(g) --------->M(g) + 1/2 X₂(g)

Enthalpy of formation = +250 kJ

M(g) + 1/2X₂(g)  → M(g) +X(g)

Enthalpy of formation = +350 kJ

M (g) + X(g) ------> M²⁺(g), + X(g)

Enthalpy of formation = +400 kJ

M²⁺ (g) + X(g) 24→ M²⁺(g), + X(g)

Enthalpy of formation = +200kJ

M²⁺(g), + X⁻(g)→ MX(s)

Enthalpy of formation= +900kJ.

Enthalpy of formation of MX = 250 +350 +406-200-900 = -100 kJ

Therefore, Enthalpy of formation of MX = -100 kJ

Since electron affinities are the heat released while the heat of sublimation is the heat absorbed then if electron affinity decreases while the heat of sublimation, increases then the overall enthalpy of formation of MX will be less negative. Hence in that case MX would be less stable.

How do weak intermolecular bond strengths affect the melting and boiling point of a substance?.

Answers

Intermolecular forces can be used to estimate relative boiling points (IMFs).The relationship between the substance's vapor pressure and boiling point depends on the strength of the IMFs.

What exactly is boiling point?

The point at which a liquid's vapor pressure equals the gas pressure above it is known as the boiled point of the liquid. The temperature that a liquid's vapor pressure equals one atmosphere is considered the liquid's typical boiling point (760 torr). The view from a distance. view from a distance of a bubble in hot water.

What other name does boiling point go by?

Boiling point and saturation temperature are synonyms. Sometimes the measurement's pressure serves as a definition for the boiling point. The standard boiling point was established by the International Alliance of Basic and Applied Chemistry (IUPAC) in 1982 as the temperature at which water boils at one bar of pressure.

what atomic or hybrid orbitals make up the sigma bond between s and f in sulfur hexafluoride, sf6 ? orbital on s orbital on f what are the approximate f-s-f bond angles ? (list all possible) ... fill in the blank 3 °

Answers

Fluorine contains one total bond, three lone electron pairs, and is sp3, hybridized, thus our approximate bond angles will be 90 degrees. Sulfur is sp3 de hybridized.

What three hybrid orbitals are there?

One s orbital and three p orbitals combine to generate four sp3 orbitals, each of which has a 25% s character and a 75% p character. This process is known as sp3 hybridization. Anytime an atom is surrounded by four groups of electrons, this kind of hybridization is important.

Describe hybridization using an example?

The process of merging two atomic orbitals to produce a new variety of hybridized orbitals is known as hybridization. Typically, this mixing creates hybrid orbitals with entirely distinct energies, forms, and sizes.

Why are a weak acid and the salt of its conjugate base used in preparing a buffer, rather than a strong acid and a salt of its conjugate base?.

Answers

An acid is more acidic than its conjugate base if its pKa value is less than or equal to seven.

When making a buffer, why do you utilize a weak acid and the salt of its conjugate base?

A weak acid and its conjugate base are present in high amounts in buffer solutions (or a weak base and its conjugate acid). Buffers are extremely resistant to fluctuations in pH because these ingredients may neutralize extra H+ or OH.

Why is it necessary to create a buffer solution using both an acid and a base?

In buffers, basic species are present to neutralize H + ions and acidic species to do the opposite. These two species must, nevertheless, be able to coexist in a solution without fully negating one another.
