The energy required to form 100.0 g of \(NO_2\) from its respective elements is approximately 72.12 kJ.

The standard heat of formation of a compound is the enthalpy change that occurs when one mole of the compound is formed from its constituent elements, with all reactants and products in their standard states at a specified temperature and pressure.

To calculate the energy required to form 100.0 g of \(NO_2\) from its respective elements, we need to first determine the number of moles of \(NO_2\) that corresponds to 100.0 g:

Molar mass of \(NO_2\) (nitrogen dioxide) = 46.0055 g/mol

Number of moles of \(NO_2\) = mass / molar mass = 100.0 g / 46.0055 g/mol = 2.1732 moles

The standard heat of formation for \(NO_2\) is 33.2 kJ/mol, which means that the formation of one mole of \(NO_2\) releases 33.2 kJ of energy. Therefore, the energy required to form 2.1732 moles of \(NO_2\) is:

Energy = (33.2 kJ/mol) x (2.1732 mol) = 72.12 kJ

The temperature at which it volume doubled at the same pressure​ is 600 kelvin.

Given that,

initial volume (V₁) = 150 cm³

final volume (V₂) = 300 cm³

initial temperature (T₁) = 27⁰C

                    = (273 + 27) K = 300 K

final temperature (T₂) = ?

As we know from Charles's law:

V₁/T₁ = V₂/T₂

or, 150 / 300 = 300 / T₂

or, T₂ = 600 K

The ideal gas volume at constant pressure is exactly proportional to its absolute temperature, as stated by Charles' law. According to Charles' law, the temperature in degrees Kelvin is directly proportional to volume if the pressure on a dry gas sample remains constant.

Charles Law is used in everyday life in ways like hot air balloons in the sky. The flame heats the air inside the balloon, accelerating and dispersing the air molecules.

The balloon can simply float because the air inside is less dense than the air outside.

A set of particles (atoms or molecules) that are constantly moving at random makes up a gas sample, according to the kinetic energy of a  molecular theory.

Moreover, these gas particles' average kinetic energy solely depends on the temperature of the gas. With an increase in gas temperature, the average kinetic energy rises (this tells that the fifth statement is true). Despite the fact that certain gas molecules will always be travelling more quickly than others, the gas can still be represented by its average kinetic energy. Because kinetic energy is proportional to the square of the speed, the second claim—that the average speed of gas molecules rises with rising temperature—is derived from this.

Answer:

Mass = 713.4 ×10⁻⁴ g

Explanation:

Given data:

Number of moles of calcium phosphate = 2.3×10⁻⁴ mol

Mass of calcium phosphate = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of calcium phosphate is 310.18 g/mol

by putting values,

2.3×10⁻⁴ mol = mass / 310.18 g/mol

Mass = 2.3×10⁻⁴ mol × 310.18 g/mol

Mass = 713.4 ×10⁻⁴ g

At 293 K, the reaction will continue 8.00 times more quickly than it occurred at 309 K.

Temperature seems to be the degree to which anything is hot or cold. Based on the facts, we need to determine the kelvin temperature of a process that has an energy of 28.90 kJ/mol and proceeds 8.000 times more quickly than it would at 309 K. = ?

Therefore, we must utilize the Equation and assign k1 = 1 and k2 = 8.00 since rate = k[A] and rates are proportional to k as long as reactant concentration does not change.

ln (k₂/k₁) = Ea/R(1/T₁ - 1/T₂)

k₂ = 8.00

k₁ = 1

Ea = 28.90J/mole

R = 8.314 J/mol⁻k

T ₁= 309 k

T₂ = ?

ln(8.00/1) = 28.90 /8.314 (1/308 - 1/T₂)

1.50 = 4.343 (1/309 - 1/T₂)

1.50 = 0.013 - 4.343/T₂

The heat of vaporization for water is 40.7 kJ/mol, which means that it takes 40.7 kJ of energy to convert 1 mole of water from a liquid to a gas phase.

The energy required to boil the water is given as 63.8 kJ.

We can set up a proportion using these values:

40.7 kJ/1 mol = 63.8 kJ/x mol

To solve for x (the number of moles of water), we can cross-multiply and solve the equation:

40.7 kJ * x mol = 63.8 kJ * 1 mol

x mol = (63.8 kJ * 1 mol) / 40.7 kJ

x mol ≈ 1.57 mol

Since we know the molar mass of water is approximately 18.015 g/mol, we can convert moles to grams:

1.57 mol * 18.015 g/mol ≈ 28.29 g

Therefore, the mass of the sample of water is approximately 28.29 grams.

Homogeneous catalysts are those that occupy the same phase as the reaction mixture (typically liquid or gas), while heterogeneous catalysts occupy a different phase. Generally, heterogeneous catalysts are solid compounds that are added to liquid or gas reaction mixtures.

The pH of the solution, we first need to calculate the molarity of the final solution. We can use the equation:

\(M_1V_1 = M_2V_2\)

where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume.

We can rearrange this equation to solve for the final molarity:

\(M_2 = (M_1V_1)/V_2\)

M₁ = 6.00 M (given)

V₁ = 5.00 mL = 0.005 L

V₂ = 100.00 mL = 0.100 L

M₂ = (6.00 M x 0.005 L) / 0.100 L = 0.300 M

Now that we have the molarity of the solution, we can find the pH using the formula:

pH = -log[H+]

We need to find the concentration of H+ ions in the solution. Since HCl is a strong acid, it dissociates completely in water, producing H+ and Cl- ions in a 1:1 ratio. Therefore, the concentration of H+ ions is the same as the molarity of the solution, which is 0.300 M.

pH = -log(0.300) = 0.522

Therefore, the pH of the solution is approximately 0.522.

Multiple drops of a sample are added to the same location on chromatography paper during spot overlaying.

Spot overlaying is the practice of applying many drops of a sample to a single spot-on chromatography paper.

It is frequently employed to boost a sample's concentration in a particular region and to make sure that there is sufficient material to produce a discernible spot on the chromatography paper.

To prevent spreading the sample and perhaps affecting the outcomes of the chromatography experiment, it is crucial to wait until each spot on the chromatography paper has dried fully before adding another spot.

Spot overlaying should generally be utilized sparingly and cautiously to prevent delaying the chromatographic procedure and compromising the precision of the results.

To raise the concentration of the sample without interfering with the experiment, it is usually preferable to utilize a larger spot or many spots of the sample at various positions on the chromatography paper.

Liam's water experiment shows an energy transformation from one form to another.

This is because when substances absorb energy, they undergo a change in state. In Liam's experiment, the water was heated and thus absorbed energy, which caused the molecules of the water to move faster and further apart. This resulted in a change from liquid to gas state, which is an example of an energy transformation.

The reason why this occurs is because the heat energy that was absorbed caused an increase in the kinetic energy of the molecules, which made them move faster and further apart.
