4.60 * 10^22 atoms P = 4.60 * 10^22/6.023 * 10^23 mole of P

which is equal to 0.0763 mole P

What are moles?

A mole is defined as the volume of substance that has the same number of discrete entities as a 12 g sample of pure 12C (atoms, molecules, ions, etc.). The Latin meaning of the term "mole" is "large mass" or "bulk," which is appropriate given that it is used as the name for this unit.

Now for the given question,

6.023 * 10^23 atoms Phosphorus = 1 mole of P

Thus, 4.60 * 10^22 atoms P = 4.60 * 10^22/6.023 * 10^23 mole of P

The total concentration of phosphate ions in an aqueous solution of magnesium phosphate is 4.2 M.

The balanced chemical equation for the reaction of dissociation of magnesium phosphate in water:

Electrons transferred from Glyceraldehyde 3 phosphate to NAD in glycolysis per glucose are 4.

The electron is a subatomic particle (denoted by symbol e−or β−) whose electric charge is negative one elementary charge. Electrons belong to first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron's mass is approximately 1836 times smaller than that of proton.

Quantum mechanical properties of electron include an intrinsic angular momentum (spin) of a half-integer value, expressed in units of the reduced Planck constant, ħ. Being fermions, no two electrons can occupy same quantum state, in accordance with the Pauli exclusion principle. Like all elementary particles, electrons exhibit properties of both the particles and waves: They can collide with the other particles and can be diffracted like light. The wave properties of electrons are easier to observe with the experiments than those of other particles like neutrons and protons because electrons have a lower mass and hence a longer de Broglie wavelength for given energy.

Electrons play an essential role in numerous physical phenomena, such as electricity, magnetism, chemistry and thermal conductivity, and they also participate in the gravitational, electromagnetic and weak interactions. Since an electron has charge, it has a surrounding the electric field, and if that electron is moving relative to an observer, said observer will observe it to generate a magnetic field. Electromagnetic fields produced from other sources will affect the motion of an electron according to Lorentz force law.

Electrons radiate or absorb energy in form of photons when they are accelerated. Laboratory instruments are capable of trapping individual electrons as well as electron plasma by use of electromagnetic fields. Special telescopes can detect the electron plasma in outer space. Electrons are involved in many applications such as the tribology or frictional charging, electrolysis, electrochemistry, battery technologies, electronics, welding, cathode-ray tubes, photoelectricity, photovoltaic solar panels, electron microscopes, radiation therapy, lasers, gaseous ionization detectors and particle accelerators.

Condensation is a process in which a gas is condensed into a liquid. During this, the quantity of energy which gets converted into heat energy from chemical energy, known as heat of condensation.  

Freezing releases energy as when liquid turns into solid or water turns into ice, the water molecules moves towards each other.

a "perfect gas" is an idealized gas with certain assumptions about its behavior.

The terms "perfect gas," "calorically perfect gas," "thermally perfect gas," and "chemically reacting gas" refer to different models used to describe the behavior of gases under various conditions. Here's an explanation of each:

1. Perfect Gas:
A perfect gas is an idealized model of a gas that follows certain assumptions to simplify its behavior and make calculations more manageable.

In a perfect gas, the particles have negligible volume and do not interact with each other except through elastic collisions.

The three main assumptions of a perfect gas are:

  a. The gas particles have no volume.
  b. There are no intermolecular forces between gas particles.
  c. The collisions between gas particles are perfectly elastic.

In real-world gases, these assumptions may not hold true, but the perfect gas model is still useful in many engineering and scientific applications,

especially at moderate temperatures and pressures.

2. Calorically Perfect Gas:
A calorically perfect gas is a type of perfect gas that assumes the specific heat capacity of the gas remains constant with temperature.

In other words, the heat capacity (the amount of heat required to raise the temperature of a substance) of the gas does not change over the temperature range of interest.

This assumption simplifies the calculation of heat transfer processes involving the gas.

In reality, most gases exhibit some variation in their specific heat capacity with temperature, but for certain applications where this variation is negligible or unimportant,

the calorically perfect gas model can be used.

3. Thermally Perfect Gas:
A thermally perfect gas is another type of perfect gas that assumes constant thermal conductivity,

which means that the gas's ability to conduct heat remains constant with temperature.

This assumption simplifies the analysis of heat conduction problems involving the gas.

In actual gases, thermal conductivity may vary with temperature and pressure, but the thermally perfect gas model is useful when the variation is negligible for the given application.

4. Chemically Reacting Gas:
A chemically reacting gas is a gas in which chemical reactions are taking place, resulting in changes in the gas composition and properties.

Unlike the previous models, this description goes beyond the idealized assumptions of a perfect gas and considers the influence of chemical reactions on the gas behavior.

Chemically reacting gases are more complex to analyze since the reaction rates, products, and energy exchanges need to be taken into account.

The composition of the gas can vary with time, and it may not be appropriate to use the assumptions of a perfect gas or its variants in these cases.

In summary, a "perfect gas" is an idealized gas with certain assumptions about its behavior.

A "calorically perfect gas" assumes constant specific heat capacity,

a "thermally perfect gas" assumes constant thermal conductivity, and a "chemically reacting gas" considers the influence of chemical reactions on the gas behavior.

Each model serves specific purposes and is applied based on the level of accuracy needed for a particular analysis or problem.
