Which particles constantly move around the center of an atom?

Answers

Answer 1

There is a nucleus at the center of an atom and inside the nucleus, there is protons and neutrons which constantly move around.

We all know that an atom is made up of three smaller particles, also knows as the electrons, protons and neutrons.

Electrons are the negatively charged particles that spin around the positive center of the atom in circles called energy levels. Its also know that their mass is so less its nearly zero. On the other hand, protons are positively charged whereas neutrons have no charge.

We know that protons and neutrons are contained in the nucleus of the atom which move around the center of an atom.

Therefore, we know the nucleus has an overall positive charge as it contains protons.

a block of titanium has nv vacancies at 300 k. what happens to the number of vacancies as the temperature increases to 600 k? group of answer choices

Answers

The quantity of vacancies grows together with a solid material's temperature. This is due to the fact that at higher temperatures, the material's atoms have greater kinetic energy and are therefore more prone to move around and leave voids behind.

The vacant regions in the crystal lattice of solid materials where atoms are absent from their predicted places are known as vacancies. These vacancies may develop for a number of reasons, including thermal vibrations, lattice contaminants, and external forces on the material. The characteristics of the material may change as a result of the existence of vacancies, such as the electrical conductivity, mechanical strength, or thermal conductivity. Designing and optimising materials for particular uses, such as in electrical devices, aerospace engineering, or nuclear power plants, requires an understanding of the behaviour of vacancies. In materials science and engineering, vacancies are thus a crucial notion.

why can't the carbon dioxide cycle easily correct for the increasing amounts of carbon dioxide introduced into our atmosphere by industrialization

Answers

The carbon dioxide cycle refers to the natural process of exchanging carbon dioxide between the atmosphere, oceans, and land. This cycle can help to regulate the levels of carbon dioxide in the atmosphere over long periods of time.

However, it is not able to easily correct for the increasing amounts of carbon dioxide that have been introduced into the atmosphere by industrialization for several reasons: Carbon dioxide emissions from human activities are much larger than natural carbon dioxide sources: Human activities, such as burning fossil fuels, deforestation, and industrial processes, have greatly increased the amount of carbon dioxide in the atmosphere.

The natural carbon sinks are not capable of absorbing all the excess carbon dioxide: The carbon dioxide cycle relies on natural carbon sinks such as forests and oceans to absorb carbon dioxide from the atmosphere. However, these natural carbon sinks have limits to their capacity and are becoming saturated with excess carbon dioxide.

The rate of carbon dioxide emissions is much faster than the rate at which natural carbon sinks can absorb carbon dioxide: The natural carbon sinks have a limited capacity to absorb carbon dioxide, and their absorption rate is much slower than the rate at which carbon dioxide is being emitted by human activities.

This means that the excess carbon dioxide remains in the atmosphere for longer periods of time, contributing to the buildup of carbon dioxide in the atmosphere.

the vapor pressure of benzene is 73.03 mm hg at 25oc. a nonvolatile, nonelectrolyte that dissolves in benzene is cholesterol . calculate the vapor pressure of the solution at 25oc when 7.462 grams of cholesterol, c27h46o (386.6 g/mol), are dissolved in 187.8 grams of benzene.

Answers

The vapor pressure of the solution at 25°C is 72.46 mmHg.

To calculate the vapor pressure of the solution, we can use Raoult's law, which states that the vapor pressure of a solution is equal to the vapor pressure of the pure solvent multiplied by the mole fraction of the solvent in the solution.

The mole fraction of the solvent, benzene, can be calculated as follows:

moles of benzene = mass of benzene / molar mass of benzene

moles of benzene = 187.8 g / 78.11 g/mol = 2.404 mol

moles of cholesterol = mass of cholesterol / molar mass of cholesterol

moles of cholesterol = 7.462 g / 386.6 g/mol = 0.0193 mol

The total number of moles in the solution is the sum of the moles of benzene and cholesterol:

total moles = 2.404 mol + 0.0193 mol = 2.423 mol

The mole fraction of benzene is:

Xbenzene = moles of benzene / total moles

Xbenzene = 2.404 mol / 2.423 mol = 0.9921

The vapor pressure of the solution can be calculated as follows:

Pbenzene-solution = Xbenzene x Pbenzene-pure

Pbenzene-solution = 0.9921 x 73.03 mmHg = 72.46 mmHg

Therefore, the vapor pressure of the solution at 25°C is 72.46 mmHg.

Calculate the ph of a buffered solution prepared by dissolving 21. 5 g benzoic acid and 37. 7 g sodium benzoate

Answers

Answer:

4.19

Explanation:

The pH of a buffer solution can be calculated using the Henderson-Hasselbalch equation:

pH = pKa + log([A-]/[HA])

where pKa is the acidic dissociation constant of the weak acid (in this case, benzoic acid), [A-] is the concentration of the conjugate base (sodium benzoate), and [HA] is the concentration of the weak acid (benzoic acid).

To find [A-] and [HA], we need to convert the masses of benzoic acid and sodium benzoate to moles.

First, let's convert the mass of benzoic acid to moles:

21.5 g ÷ 122.12 g/mol = 0.176 moles

Next, let's convert the mass of sodium benzoate to moles:

37.7 g ÷ 144.11 g/mol = 0.262 moles

Now we can use the mole ratios to find [A-] and [HA]. Since sodium benzoate is the salt of benzoic acid, the ratio of sodium benzoate to benzoic acid is 1:1, so [A-] = [HA] = 0.176 moles.

Finally, we can use the Henderson-Hasselbalch equation to calculate the pH of the buffer solution:

pH = pKa + log([A-]/[HA]) = 4.19 + log(0.176/0.176) = 4.19

So the pH of the buffer solution is 4.19.

The pH of a buffer solution prepared by dissolving 21. 5 g benzoic acid and 37. 7 g sodium benzoate  is 4.19.

What is buffer?

Buffer is a chemical which resists change in pH on addition of acid and base.There are 2 types of buffers.

The pH of a buffer solution can be calculated using the Henderson-Hasselbalch equation:

pH = pKa + log([A-]/[HA]) where pKa is the acidic dissociation constant of the weak acid (in this case, benzoic acid), [A-] is the concentration of the conjugate base (sodium benzoate), and [HA] is the concentration of the weak acid (benzoic acid).

To find [A-] and [HA], we need to convert the masses of benzoic acid and sodium benzoate to moles.let's convert the mass of benzoic acid to moles:21.5 g ÷ 122.12 g/mol = 0.176 moles

Next, let's convert the mass of sodium benzoate to moles:

37.7 g ÷ 144.11 g/mol = 0.262 moles

Now use the mole ratios to find [A-] and [HA]. Since sodium benzoate is the salt of benzoic acid, the ratio of sodium benzoate to benzoic acid is 1:1, so [A-] = [HA] = 0.176 moles.

Finally,  use the Henderson-Hasselbalch equation to calculate the pH of the buffer solution:

pH = pKa + log([A-]/[HA]) = 4.19 + log(0.176/0.176) = 4.19

∆T = Km Kfp chloroform = 4.68 oC/m Freezing point chloroform = -63.5 oC

Answers

The freezing point of a solution is -63.575 °C

The freezing point depression of a solution can be calculated by using the equation:

∆T = Km • Kfp

Where ∆T is the freezing point depression of the solution, Km is the molar concentration of the solute and Kfp is the freezing point depression constant for the solvent.

For this problem, the molar concentration of the solute (benzene) is

[tex]\frac{ 1.25 g}{78 g/mol }\\\\= 0.0161 mol/kg.[/tex]

The freezing point depression constant for chloroform is 4.68 °C/m.

Therefore, the freezing point depression of the solution is:

∆T = 0.0161 mol/kg • 4.68 °C/m = 0.075 °C

The freezing point of the solution is then calculated by subtracting the freezing point depression from the freezing point of the pure solvent:

Freezing point of solution = -63.5 °C - 0.075 °C = -63.575 °C

Explain how the basic laws of matters led to the formulation of daltons atomic theory

Answers

Dalton's Atomic Theory proposed a model of the atom as a small, indivisible, and indestructible particle. This theory was based on a set of observations and experiments that followed from the basic laws of matter.

One of the key observations was the law of definite proportions, which states that the proportions of elements in a compound are always the same regardless of the amount or source of the compound. For example, water always consists of two hydrogen atoms and one oxygen atom, no matter where it comes from or how much is present. This observation led to the conclusion that elements combine in fixed ratios to form compounds, suggesting that the elements themselves must be made up of individual, uniform particles.

Another important observation was the law of conservation of mass, which states that the total mass of a system remains constant during a chemical reaction, indicating that matter cannot be created or destroyed. This led to the conclusion that chemical reactions involve the rearrangement of individual particles, rather than the creation or destruction of matter.

Finally, the law of multiple proportions, which states that when two elements combine to form more than one compound, the ratio of the masses of one element that combine with a fixed mass of the other element is always a ratio of small whole numbers. This observation led to the conclusion that elements could combine in different ratios to form different compounds, suggesting that the elements must consist of individual particles with different masses.

Based on these observations, Dalton proposed his Atomic Theory, which stated that:

All matter is made up of atoms, which are small, indivisible particles.Atoms of a given element are identical in size, mass, and other properties.Atoms cannot be created, destroyed, or transformed into atoms of another element.Atoms of different elements combine in fixed ratios to form compounds.Chemical reactions involve the rearrangement of atoms, but no creation or destruction of matter occurs.

Overall, Dalton's Atomic Theory was an attempt to explain the basic laws of matter through a model of the atom as a small, indivisible, and indestructible particle that could explain the chemical behavior of elements and compounds. It provided a framework for understanding the behavior of matter and set the stage for further research into the nature of the atom and the fundamental principles of chemistry.

if you started with a 125g sample of u-235, how much of the sample would be remaining after 3 half-lives and how many years would have passed?

Answers

The half-life of uranium-235 (U-235) is 704 million years. Therefore, after three half-lives, the amount of U-235 remaining will be 15.624g.

(1/2)^3 = 1/8
So, only 1/8th of the initial amount of U-235 will remain. We can calculate the amount of U-235 remaining as:
125 g × (1/8) = 15.625 g
So, 15.625 g of U-235 will remain after 3 half-lives.
The time it takes for three half-lives to pass can be calculated as:
3 × 704 million years = 2.112 billion years
Therefore, 2.112 billion years will have passed after 3 half-lives.
Note that the calculation assumes that the decay of U-235 follows first-order kinetics and that the decay products do not interfere with the decay process.

problem 20.17 show how this carboxylic acid can be converted into the corresponding alcohol using nabh4 as the reducing agent. hint: can you convert the carboxylic acid into a different acid derivative first?

Answers

The  reaction sequence allows for the conversion of a carboxylic acid to the corresponding alcohol using NaBH4 as the reducing agent, by first converting the carboxylic acid into a more reactive derivative.

To convert a carboxylic acid into the corresponding alcohol using NaBH4 as the reducing agent, we first need to convert the carboxylic acid into a more reactive derivative, such as an ester or acid chloride. This is because carboxylic acids are relatively unreactive towards reduction.

One way to do this is to react the carboxylic acid with an alcohol in the presence of an acid catalyst to form an ester. The ester can then be reduced to the corresponding alcohol using NaBH4. Alternatively, the carboxylic acid can be converted to an acid chloride by reaction with thionyl chloride, which can then be reduced to the alcohol using NaBH4.

For example, consider the conversion of acetic acid to ethanol. Acetic acid can be converted to the more reactive acetyl chloride by reaction with thionyl chloride:

CH3COOH + SOCl2 → CH3COCl + SO2 + HCl

The resulting acetyl chloride can then be reduced to ethanol using NaBH4:

CH3COCl + NaBH4 → CH3CH2OH + NaCl + B(OH)3

Overall, this reaction sequence allows for the conversion of a carboxylic acid to the corresponding alcohol using NaBH4 as the reducing agent, by first converting the carboxylic acid into a more reactive derivative.

how does it become less dense if one were to ride a hot air balloon up into the atmosphere in concentration of gases,

Answers

A gas's molecules move more quickly and collide with one another and the container walls more frequently as its temperature rises. The gas's density drops as a result of this increase in volume.

The density of the air within the balloon reduces as it heats up and expands. Pressure remained stable despite ongoing changes in volume and temperature. In contrast, a hot air balloon has a density that is initially equal to the air around it. . As the air inside it warms up, its density falls until it has a buoyant force acting on it that can lift not only the balloon but also the basket and passengers. Hot air balloons ascend into the air because the warmer, less dense air within the balloon has a lower density than the air outside (cooler air). The system is subject to a buoyant force because the balloon and basket move a fluid that is heavier than the balloon and basket.

a bar graph that shows all the organic compounds in an egg.

Answers

The bar graph below shows the organic compounds found in an egg. The y-axis displays the amount of each organic compound in percentage, while the x-axis displays the type of organic compound.

What is organic compound?

Organic compounds are compounds composed of carbon, hydrogen, and other elements such as oxygen, nitrogen, sulfur, phosphorus, and other elements. Carbon and hydrogen are the two most abundant elements in organic compounds, making up about 90% of the compounds. Organic compounds can be divided into two categories, natural and synthetic. Natural organic compounds are those that are produced in or derived from living organisms, such as carbohydrates, proteins, and lipids. Synthetic organic compounds are those that are made by humans, such as plastics, dyes, and medicines.

The bar graph shows that the most abundant organic compound in an egg is water, making up approximately 75% of the egg's total mass. This is followed by proteins at approximately 13%, fat at approximately 11%, carbohydrates at approximately 1%, and other organic compounds making up approximately 0.2%.

by titration, 15.0 ml of 0.1008 m sodium hydroxide is needed to neutralize a 0.0907 g sample of a weak acid. part a what is the molar mass of the acid if it is monoprotic?

Answers

A 0.0907 g sample of a weak acid requires 15.0 ml of 0.1008 m sodium hydroxide to be neutralized by titration. the molar mass of the monoprotic weak acid is 60.13 g/mol.

We can use the balanced chemical equation of the neutralization reaction to calculate the number of moles of the weak acid that reacted with the sodium hydroxide:

Weak acid + NaOH → NaA + H2O

where NaA is the sodium salt of the weak acid.

The number of moles of sodium hydroxide used can be calculated from its concentration and the volume used in the titration:

n(NaOH) = C(NaOH) x V(NaOH)

n(NaOH) = 0.1008 mol/L x 0.0150 L

n(NaOH) = 0.00151 mol

Since 1 mole of weak acid reacts with 1 mole of sodium hydroxide, the number of moles of the weak acid is also 0.00151 mol.

The molar mass of the weak acid can be calculated using its mass and the number of moles:

Molar mass = mass / moles

Molar mass = 0.0907 g / 0.00151 mol

Molar mass = 60.13 g/mol

Therefore, the molar mass of the monoprotic weak acid is 60.13 g/mol.

Magnets and electric charges show certain similarities. For example, both magnets and electric charges can exert a force on their surroundings. This force, when produced by a magnet, is called a magnetic field. When it is produced by an electric charge, the force is called an electric field. It has been observed that the strength of both magnetic fields and electric fields is inversely proportional to the square of the distance between a magnet or an electric charge and the objects that they affect. Below, three scientists debate the relationship between electricity and magnetism.Scientist 1:Electricity and magnetism are two different phenomena. Materials such as iron, cobalt, and nickel contain magnetic domains: tiny regions of magnetism, each with two poles. Normally, the domains have a random orientation and are not aligned, so the magnetism of some domains cancels out that of other domains; however, in magnets, domains line up in the same direction, creating the two poles of the magnet and causing magnetic behavior.In contrast, electricity is a moving electric charge which is caused by the flow of electrons through a material. Electrons flow through a material from a region of higher potential (more negative charge) to a region of lower potential (more positive charge). We can measure this flow of electrons as current, which refers to the amount of charge transferred over a period of time.Scientist 2:Electricity and magnetism are similar phenomena; however, one cannot be reduced to the other. Electricity involves two types of charges: positive and negative charge. Though electricity can occur in a moving form (in the form of current, or an electric charge moving through a wire), it can also occur in a static form. Static electricity involves no moving charge. Instead, objects can have a net excess of positive charge or a net excess of negative chargebecause of having lost or gained electrons, respectively. When two static positive electric charges or two static negative electric charges are brought close together, they repel each other. However, when a positive and a negative static charge are brought together, they attract each other.Similarly, all magnets have two poles. Magnetic poles that are alike repel each other, while dissimilar magnetic poles attract each other. Magnets and static electric charges are alike in that they both show attraction and repulsion in similar circumstances. However, while isolated static electric charges occur in nature, there are no single, isolated magnetic poles. All magnets have two poles, which cannot be dissociated from each other.Scientist 3:Electricity and magnetism are two aspects of the same phenomenon. A moving flow of electrons creates a magnetic field around it. Thus, wherever an electric current exists, a magnetic field will also exist. The magnetic field created by an electric current is perpendicular to the electric current's direction of flow.Additionally, a magnetic field can induce an electric current. This can happen when a wire is moved across a magnetic field, or when a magnetic field is moved near a conductive wire. Because magnetic fields can produce electric fields and electric fields can produce magnetic fields, we can understand electricity and magnetism as parts of one phenomenon: electromagnetism.In an experiment, an iron bar that showed no magnetism was heated and allowed to cool while aligned North-South with the Earth's magnetic field. After it cooled, the iron bar was found to be magnetic. Scientist 1 would most likely explain this result by saying which of the following?Possible Answers:1. Interference occurred between the electric field of the bar and the magnetic field of the Earth, causing the bar to become magnetic.2. The experiment caused the magnetic domains of the bar to move out of alignment with each other.3. The experiment induced an electric current in the bar, causing the bar to become magnetic.4. The experiment allowed the magnetic domains of the bar to line up, causing the bar to become magnetic.5. The experiment caused the two magnetic poles of the bar to move so that they were aligned with the Earth's magnetic field.
