The process that correctly describes the growth in the number of ionized nitrogen molecules over time is D. The number of ionized molecules increases exponentially with each ionized molecule ionizing 3 other molecules every nanosecond.

Let's analyze the equation tN2 = 3⋅N, where N is the number of ionized molecules and t is the time in nanoseconds.

The equation states that the number of ionized molecules at time t is equal to 3 times the number of ionized molecules at the previous time step.

This implies that each ionized molecule ionizes 3 other molecules every nanosecond.

A physicist is studying the nature of static discharge by applying a voltage across a microscopic tube filled with nitrogen.

Static discharge is an event that takes place when there is a sudden flow of electric charge between two objects with different electrical potentials. This electric charge transfer results in a brief burst of electromagnetic energy (EMI or EMF), which can sometimes be observed as a visible spark in low-light conditions or heard as a crackling sound in high-quality audio systems.

The nature of static discharge is dependent on a variety of factors, including the composition of the material, the temperature and humidity, the electrical potential between the two objects, and the distance between the objects. Typically, static discharge occurs more frequently in environments with low humidity, such as during the winter months or in arid regions, as moisture acts as an insulator and prevents the buildup of electrical charge. In addition, materials that are good electrical conductors, such as metals, are more likely to experience static discharge than materials that are poor conductors, such as plastics or rubber.

Therefore, the correct description of the growth in the number of ionized nitrogen molecules over time is:

Physical vapor deposition is a highly precise and controlled process for depositing thin films with high purity and uniformity.

The physical vapor deposition process is a type of vaporization process used for depositing thin films. It differs from other processes in that it involves the physical transfer of material from a source to a substrate. This is accomplished through the use of a vacuum chamber, in which the source material is heated to a high temperature, causing it to evaporate and form a vapor. The vapor then condenses onto the substrate, forming a thin film. Other deposition processes, such as chemical vapor deposition, involve the use of chemical reactions to deposit materials onto a substrate.

The aluminum sulfide (Al\(_{2}\)(SO\(_{4}\))\(_{3}\))  ) contains aluminum with a mass% of 23.7%. Option A is answer.

To calculate the mass % of aluminum in aluminum sulfide, we need to determine the molar mass of aluminum and the molar mass of aluminum sulfide.

The molar mass of aluminum (Al) is 26.98 g/mol, as indicated by its atomic mass on the periodic table.

The molar mass of aluminum sulfide (Al\(_{2}\)(SO\(_{4}\))\(_{3}\))  can be calculated by summing the molar masses of its constituent elements. The molar mass of sulfur (S) is 32.07 g/mol, and the molar mass of oxygen (O) is 16.00 g/mol. There are three sulfur atoms and 12 oxygen atoms in aluminum sulfide.

Therefore, the molar mass of aluminum sulfide is:

(2 * 26.98 g/mol) + (3 * (32.07 g/mol + 4 * 16.00 g/mol)) = 2 * 26.98 g/mol + 3 * 96.28 g/mol = 2 * 26.98 g/mol + 288.84 g/mol = 339.80 g/mol

To calculate the mass % of aluminum in aluminum sulfide, we can use the formula:

(Molar mass of aluminum / Molar mass of aluminum sulfide) * 100

(26.98 g/mol / 339.80 g/mol) * 100 = 7.9446... %

The equilibrium concentration of NOF is 0.067 M.

To determine the equilibrium concentration of NOF, we need to use the equilibrium constant (Kc) and the initial concentrations of the reactants. The equilibrium constant expression for the given reaction is:

Kc = [NOF]² / ([NO]² * [F₂])

Given that Kc = 7.2 × 10⁻⁴ and the initial concentrations of NO and F₂ are both 0.92 M, we can substitute these values into the equilibrium constant expression:

7.2 × 10⁻⁴ = [NOF]² / (0.92)²

Rearranging the equation and solving for [NOF], we get:

[NOF]² = 7.2 × 10⁻⁴ * (0.92)²

[NOF]² = 6.386 × 10⁻⁴

[NOF] = √(6.386 × 10⁻⁴)

[NOF] ≈ 0.067 M

Therefore, the equilibrium concentration of NOF is approximately 0.067 M when the reaction starts with initial concentrations of 0.92 M for both NO and F₂.

So, at STP, there are around 891 grammes of nitrogen gas in every 759 litres.

The two stable isotopes of naturally occurring nitrogen (7N) are nitrogen-14 and nitrogen-15, with nitrogen-14 constituting 99.6% of all naturally existing nitrogen. Along with one nuclear isomer, 11mN, fourteen radioisotopes with atomic masses ranging from 10 to 25 are also known.

Assuming "ST" refers to standard temperature and pressure (0°C and 1 atm), we can use the ideal gas law to calculate the mass of nitrogen gas:

PV = nRT

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

The temperature and pressure are 273.15 K and 1 atm, respectively, at STP.

To solve for n, the number of moles, we can rearrange the ideal gas law equation as follows:

n = PV / RT = (1 atm) * (759 L) / (0.0821 L·atm/(mol·K) * 273.15 K) = 31.8 mol

Now we can calculate the mass of nitrogen gas:
