Answers

Answer 1

If the chef applies energy to the sauce, it will changes to liquid state, as the particles from the  gels state move faster apart and reduces their intermolecular attraction forming the liquid phase.

What is phase change ?

The phase change of a material is a physical change in which the material changes from one state of matter to the other. For example boiling, melting or vaporizing are all phase changes.

In solid state the particles are closely packed by strong intermolecular forces. In liquids , particles have some more space to flow apart. In gaseous state the particles are far apart and free to diffuse anywhere.

When the gelly sauce is heated the particles are absorbing enough energy to weaken the intermolecular force of attraction. They gain kinetic energy to move faster and form a liquid state.

as the concentration of ferrous iron decreases your sample absorbs _______ light, therefore ______ light reaches the detector.

Answers

As the concentration of ferrous iron decreases, your sample absorbs less light, therefore more light reaches the detector.

What happens when a sample containing ferrous iron is exposed to light?

When a sample containing ferrous iron is exposed to light at a specific wavelength, some of the light is absorbed by the ferrous iron molecules in the sample. This results in a decrease in the intensity of the light that reaches the detector, which is measured as the absorbance of the sample.

The amount of light absorbed by the ferrous iron molecules is directly proportional to their concentration in the sample. Therefore, if the concentration of ferrous iron in the sample decreases, there are fewer molecules to absorb the light, and more light reaches the detector. This results in a lower absorbance reading for the sample.

What intermolecular forces are shared between CH₃CH₂CH₂F and CH₃CH₂CH₂OH?A) Dispersion forces only.B) Dipole-dipole forces only.C) Dispersion forces, dipole-dipole forces, and hydrogen bonding.D) Dispersion forces and dipole-dipole forces

Answers

A is the best option. Dispersion forces act on both molecules, as they do on all molecules.

The least powerful intermolecular force exists through the London dispersion. When the electrons in two nearby atoms occupy positions that cause the atoms to temporarily form dipoles, a transient attractive force called the London dispersion force is created. There are occasions when this force is referred to as an induced dipole-induced dipole attraction. When the temperature is decreased enough, the attraction forces known as London forces drive nonpolar substances to condense into liquids and to freeze into solids.  Because electrons are always moving, when their distribution around the nucleus is asymmetric, an atom or molecule may suddenly generate a dipole.

The development of the dipole in the first atom or molecule might, in turn, distort a second atom or molecule because electrons repel one another, creating an electric attraction between the two atoms or molecules. Any two molecules, including polar molecules, exhibit dispersion forces when they are just inches away from one another.

The Intermolecular Forces shared between CH₃CH₂CH₂F and CH₃CH₂CH₂OH are Dispersion forces, dipole-dipole forces, and hydrogen bonding.

CH₃CH₂CH₂F is a fluorocarbon, which is a polar molecule due to the electronegativity difference between carbon and fluorine. CH₃CH₂CH₂OH is an alcohol, which is also a polar molecule due to the presence of the highly electronegative oxygen atom.

Both molecules have dispersion forces, which are the attractive forces between temporary dipoles that result from the movement of electrons within molecules. In addition, both molecules have dipole-dipole forces, which are the attractive forces between the permanent dipoles that result from the polar nature of the molecules.

However, CH₃CH₂CH₂OH also has hydrogen bonding, which is a type of dipole-dipole force that occurs specifically between molecules that contain a hydrogen atom bonded to a highly electronegative atom such as oxygen, nitrogen, or fluorine. In CH₃CH₂CH₂OH, the hydrogen atom is bonded to the oxygen atom, which is highly electronegative, allowing for hydrogen bonding to occur.

1. 5 moles of ethanol, 6 moles of ethanoic acid, 6 moles of ethyl ethanoate and 4 moles of water are mixed together in a separatory funnel at 15°C. After equilibrium was established, only 4​ ethanoic acid

Answers

If only 4 moles of ethanoic acid were found in the funnel. the equation for the reaction between ethanol and ethanoic acid to form ethyl ethanoate and water is CH3CH2OH + CH3COOH ⇌ CH3COOCH2CH3 + H2O.

What is the equation for the reaction between ethanol and ethanoic acid?

a) The balanced chemical equation for the reaction between ethanol and ethanoic acid to form ethyl ethanoate and water is:

CH3CH2OH + CH3COOH ⇌ CH3COOCH2CH3 + H2O

b) To determine the number of moles of each component present at equilibrium, we can use the information given in the problem statement. Initially, we have:

5 moles of ethanol

6 moles of ethanoic acid

6 moles of ethyl ethanoate

4 moles of water

At equilibrium, we have:

4 moles of ethanoic acid (so we have lost 2 moles of ethanoic acid)

5 - x moles of ethanol (where x is the number of moles of ethanol that reacted to form ethyl ethanoate)

6 moles of ethyl ethanoate (since it is a product, the amount does not change)

4 + x moles of water (since water is also a product, its amount increases as the reaction proceeds)

Since the reaction is in stoichiometric proportions, the number of moles of ethanoic acid lost is equal to the number of moles of ethyl ethanoate and water produced. Therefore, we can set up the following equation to solve for x:

2x = 2

x = 1

Therefore, at equilibrium, we have:

4 moles of ethanoic acid

4 moles of ethanol (5 - 1)

6 moles of ethyl ethanoate

5 moles of water (4 + 1)

c) The equilibrium constant for the reaction is given by the following expression:

Kc = [CH3COOCH2CH3][H2O]/[CH3CH2OH][CH3COOH]

Plugging in the concentrations at equilibrium, we get:

Kc = [(6 mol)/(L) * 5 mol/L]/[(5 mol/L) * (4 mol/L)]

Kc = 1.5

Therefore, the equilibrium constant for this reaction is 1.5. Note that since the value of Kc is greater than 1, the reaction lies to the right at equilibrium, meaning that the formation of ethyl ethanoate is favored.

An Alpha Particle is really the same thing as a Helium Nucleus, it is made up of two protons and two neutrons. Why did Rutherford decide to use Alpha Particles in his experiment to test the Plum Pudding Model?

Answers

Answer:

Ernest Rutherford used alpha particles in his famous gold foil experiment to test the Plum Pudding Model of atomic structure because they have a high energy and a large mass.

The Plum Pudding Model proposed by J.J. Thomson suggested that atoms consisted of a uniform, positively charged sphere with negatively charged electrons embedded within it, much like plums in a pudding. However, Rutherford's observations of the scattering of alpha particles as they passed through the gold foil showed that the Plum Pudding Model was incorrect.

When Rutherford directed a beam of alpha particles at a thin sheet of gold foil, he expected the alpha particles to pass straight through or be slightly deflected by the electrons in the gold atoms. However, he observed that a small fraction of the alpha particles were deflected at large angles or even bounced back in the direction from which they came. This could only be explained if the mass of the atom was concentrated in a small, positively charged nucleus at the center, surrounded by mostly empty space.

The reason that Rutherford used alpha particles in his experiment was because their high energy and large mass allowed them to penetrate the atoms of the gold foil and interact with the positively charged nucleus, revealing its presence and disproving the Plum Pudding Model.

Explanation:

Answer:

Rutherfords gold foil experiment involved sending positively charged alpha particles through a thin sheet of gold foil and defecting if there was any deflection of the particles. He found that most passed straight through yet some particles showed some deflection. This result contradicts the plum-pudding model of the atom because the plum pudding model does not explain the deflection of alpha particles.

Explanation:

Alpha particles are positive, so they might be repelled by any areas of positive charge inside the gold atoms. Assuming a plum pudding model of the atom, Rutherford predicted that the areas of positive charge in the gold atoms would deflect, or bend, the path of all the alpha particles as they passed through.

What is nitrogen dioxide formula

Answers

The nitrogen dioxide formula is NO2. It is a chemical compound composed of one nitrogen atom and two oxygen atoms. Nitrogen dioxide is a reddish-brown gas with a pungent odor and is a common air pollutant.

Nitrogen dioxide is formed by the reaction of nitrogen oxide (NO) and oxygen (O2) in the atmosphere, typically from the combustion of fossil fuels in vehicles and power plants. It can also be formed by lightning, forest fires, and volcanic eruptions.

The NO2 molecule has a linear shape, with the nitrogen atom in the center and the two oxygen atoms on either side. The nitrogen atom has five valence electrons, and each oxygen atom has six valence electrons. In order to form a stable molecule, nitrogen shares one of its electrons with each of the oxygen atoms, forming two covalent bonds. This results in a nitrogen-oxygen double bond, as well as a nitrogen-oxygen single bond.

The Lewis structure of NO2 shows that the molecule has an unpaired electron on the nitrogen atom, making it a free radical. This unpaired electron makes NO2 highly reactive and unstable, which contributes to its role as an air pollutant.

NO2 is known to cause respiratory problems and other health issues in humans and animals, and it can also contribute to the formation of acid rain. As a result, many countries have regulations in place to limit the emissions of NO2 and other air pollutants.

In summary, the nitrogen dioxide formula is NO2, a chemical compound composed of one nitrogen atom and two oxygen atoms. It is a common air pollutant formed by the reaction of nitrogen oxide and oxygen in the atmosphere, typically from the combustion of fossil fuels.

Answers

The mass of helium in the tire is 0.0452 g. To calculate the mass of helium in the tire, we need to use the ideal gas law, which relates the pressure, volume, and temperature of a gas to its number of moles and therefore its mass: PV = nRT

To calculate the mass of helium in the tire, we need to use the ideal gas law, which relates the pressure, volume, and temperature of a gas to its number of moles and therefore its mass:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the temperature.

We know the pressure, volume, and temperature of the helium in the tire, so we can solve for the number of moles of helium:

n = PV/RT

where R = 0.08206 L atm/K mol is the universal gas constant.

Substituting the values given:

n = (7.80 atm) x (0.365 L) / [(0.08206 L atm/K mol) x (25°C + 273.15)]

n = 0.0113 mol

Finally, we can calculate the mass of the helium using the molar mass of helium, which is 4.003 g/mol:

mass = n x molar mass

mass = 0.0113 mol x 4.003 g/mol

mass = 0.0452 g

Answers

option (c) 1.424×10^24 oxygen atoms.To determine the number of oxygen atoms in 52.06 g of carbon dioxide, we first need to calculate the number of moles of carbon dioxide present in the given sample.

The molar mass of carbon dioxide is 44.01 g/mol, which means that 1 mole of carbon dioxide contains 6.022×10^23 molecules. Therefore, the number of moles of carbon dioxide present in 52.06 g of the compound can be calculated as follows:

Number of moles = Mass/Molar mass = 52.06 g / 44.01 g/mol = 1.182 mol

How do you define "compound"?

A compound is indeed a substance that consists of two or more separate chemical elements united in a certain order in chemistry. When the parts came together, they interact and create covalent bond that are challenging to break. The sharing or trading of electrons between atoms results in the formation of these bonds.

What are mixtures and compounds?

A compound is a substance formed of bound atoms from different types. Mixture: a combination comprising two or more substances that haven't chemically interacted to form bonds with one another; each component of the combination retains its own characteristics.

The equilibrium constant K for a system at equilibrium expresses a particular ratio of equilibrium _______________ of products and reactants at a particular _____________. The value of K is also equal to the ratio of the rate _____________ for the forward and reverse reactions.

Answers

The equilibrium constant K for a system at equilibrium expresses a particular ratio of equilibrium Concentrations of products and reactants at a particular temperature. The value of K is also equal to the ratio of the rate constants for the forward and reverse reactions.

What causes a reverse reaction?

If the reaction proceeds as stated and becomes exothermic, a rise in temperature will therefore cause the opposite reaction, which will lead to a reduction in the amount of the products or an increase in the number of reactants. If the current is lowered, the result will be the opposite.

Are all reverse reactions endothermic?

The endothermic reaction occurs if the energy needed to break bonds is greater than the energy produced when new bonds are formed. For reversible processes, one of the two reactions will be exothermic—either the forward or backward reaction—and the other can be endothermic.
