an aluminum aerosol can will burst if the pressure inside reaches 210.0 psi. if the can initially contains an ideal gas at 518.0 kpa at 298.15 k, at what temperature (in k) will the can burst?

According to Le Chatelier's principle, if a cation forms an insoluble precipitate with [AgCl], the direction that is favored when added to the system is for the precipitate to form.

When a cation is added to a solution containing Ag+ ions and Cl- ions, it can form an insoluble precipitate with AgCl if it is one of the cations that are capable of doing so. This will cause AgCl to come out of the solution and form a solid precipitate.

This reaction is exothermic, releasing heat, and the formation of the precipitate will consume Ag+ and Cl- ions, which will decrease the concentration of the ions in the solution.

By consuming the reactants, the formation of the precipitate will cause the reaction to shift to the right, in the direction of the formation of the precipitate. This is in agreement with Le Chatelier's principle which states that a system at equilibrium will shift to counteract the changes imposed on it.

According to the question: the Kb for ethylamine is 7.59 x 10^-14.

Ethylamine is an organic compound with a chemical formula of C2H7N. It is a colorless liquid with an ammonia-like odor.

Kb is the acid dissociation constant for bases. It is defined as the equilibrium constant for the reaction in which a base reacts with water to form its conjugate acid and hydroxide ions:
B + H2O → HB+ + OH-
The Kb for ethylamine can be calculated using the equation:
Kb = [HB+][OH-] / [B]

For a 0.100 M solution of ethylamine, the concentration of ethylamine is 0.100 M and the pH is 11.87.
First, we need to calculate the concentration of hydroxide ions ([OH-]) from the pH.
The pH of a solution is equal to the negative logarithm of the molar concentration of hydrogen ions ([H+]):
pH = -log[H+]
Therefore, the molar concentration of hydroxide ions ([OH-]) can be calculated as:
[OH-] = 10^-pH = 10^-11.87 = 7.59 x 10^-12 M
Now, we can calculate the Kb for ethylamine as:
Kb = [HB+][OH-] / [B]
  = (7.59 x 10^-12 M) / (0.100 M)
  = 7.59 x 10^-14
Therefore, the Kb for ethylamine is 7.59 x 10^-14.

The new pressure of the gas is 2.75 atm.

Standard temperature and pressure refers to the conditions at temperature 0°C or 273K and pressure 1 atm.

According to Boyle's law, "The volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant. "

This means that with the increase in volume increases, there will be a decrease in pressure and vice versa.

This gas law  equation is represented as:

P₁V₁ =P₂V₂

where,

P₁ and P₂ are initial and final pressure respectively.

V₁ and V₂ are initial and final volume respectively.

Given here,

P₁= 1 atm

V₁= 1.24 L

V₂= 451 ml = 0.451 L

To find: P₂

using the equation,

P₁V₁ =P₂V₂

⇒1 × 1.24 L = P₂ × 0.451 L

⇒  P₂ = 2.75 atm

Thus, the new pressure is 2.75 atm

An element in which the highest occupied s and p sublevels are filled is called a noble gas or an inert gas.

The noble gases are a group of elements in the periodic table that are located in the far right column, these elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).

The noble gases have a full valence shell, meaning that their outermost electron shell is filled with the maximum number of electrons. This gives them a stable electron configuration and makes them unreactive with other elements. Because of this, they are also referred to as "inert" gases.

Noble gases are chemically unreactive due to their filled valence shells, which makes them a unique group of elements and they are used in a wide range of industrial and medical applications.

The term "partial pressure" refers to the amount of pressure that each gas in a mix exerts. A mole fraction of the a gas,x, can also be used to formulate Dalton's law.

The partial pressure formula: what is it?

Partial pressures can be calculated in one of two ways: 1) To determine the individual pressures of each gas in a mixture, use PV = nRT. 2) Determine the proportion of pressure from of the total pressure that may be assigned to each single gas by using the molar concentration of each gas.

What is the name for partial pressure?

The idea of partial pressure is derived from the fact so each individual gas contributes to the overall pressure in a given proportion, which corresponds to its partial pressure. In order to characterise all the pieces, it is essentially equivalent to taking a percent or proportion of the whole.

The maximum amount of NaCl possible would be 5.85 grams.

From the balanced equation of the reaction, the mole ratio of sodium that reacts to sodium chloride that is formed is 1:1. Thus, the first thing would be to convert the mass of the sodium given to its mole equivalent.

Mole = mass/molar mass

Mole of 2.3 g sodium = 2.3/23 = 0.1 mol

Since the mole equivalent of the sodium that reacts is 0.1, the mole equivalent of the sodium chloride that is produced will also be 0.1 since the mole ratio is 1:1.

Thus, the mass of 0.1 mol sodium chloride can be deduced as follows:

Mass = mole x molar mass

Molar mass of NaCl = 23 + 35.5 = 58.5 g/mol

Mass of 0.1 mo of NaCl = 0.1 x 58.5

                                       = 5.85 grams.

One of the fissile isotopes that undergo an important and crucial nuclear fission reactions is U-235 which in turn forms a chain reaction. A nuclear fission can be defined as a process of radioactive decay where a heavier nucleus splits further into the two or more lighter elements by absorbing a neutron and releasing its multiples along with great amount of energy.

Taking up the example of Uranium-235, when it's bombarded with small neutrons, the nucleus of U-235 absorbs one of them and turns to heavier U-236 which remains unstable for an infinitesimal time.

The most common symbol for density is (the lower case Greek letter rho), but the Latin letter D is also an option. It is sometimes modified by the dimensionless value "relative density" as well as "specific gravity," i.e. the ratio of the denseness of the material compared to a standard material, usually water, to simplify density comparisons across different systems of units.
