The gas in the container has a 178mmHg pressure. The gas's new atmospheric pressure is 1.47 atm. Ideal gas equation 124 K are equal to 0. 1243 moles of fluorine.

Since its particles have no volume, a perfect gas should be able to condense to a volume of zero. The actual gas particles occupy space.

Condensation is the process of changing a gas into a liquid form with volume. The substance is no longer a gas, hence the gas laws do not apply to it. The actual gas particles occupy space. A liquid with volume will be created from a condensed gas.

The gas law does not apply because the substance is no longer a gas. Gas particles actually attract one another.

The ideal gas equation is expressed as

P V = n R T

8. The gas law is :

P₁ V₁ = P₂ V₂

P₂ =  P₁ V₁ / V₂

P₂ = ( 256.4 × 362 ) / 251

    = 178mmHg

9. P₁ V₁ / T₁ = P₂ V₂ / T₂

P₂ = P₁ V₁ T₂ V₂T₁

P₂ = ( 1 × 32.4 × 352) / 28.4 × 273

   = 1.47 atm

The pressure is 1.47 atm

10. P V = n R T

T = P V / n R

T = ( 2.02 × 625 ) / 0.1243 × 0.082

T = 124 K

Thus, the temperature is 124 K.

The pH value is the negative log of H⁺ ions. The pH value of the KBrO solution is 11.3.

The pH value is used to calculate the strongness of acid and base. The value of pH is from 0 to 14.

Let the following equations will be

KOH + HBrO → KBrO + H₂O

The salt, when dissolved in H₂O, produces an alkaline solution.

Since OH⁻ is produced, this is a Kb problem.

BrO⁻ + H₂O → HBrO + OH⁻

Kb = [HBrO][OH⁻]/[BrO⁻] = (x)(x)/(0.800 -x) = 5.0 × 10⁻⁶

Since Kb is small compared to 0.800, we can neglect the x-term to simplify the calculation.

x² / 0.800 = 5 × 10⁻⁶

             x = 2 × 10⁻³

Then the pH value will be

pOH = -log[OH⁻] = -log (2.0 × 10⁻³) = 2.69

pH + pOH = 14

          pH = 14 - pOH

          pH = 14 - 2.69

Answer:

Sodium (Na) is a cation, which means it has a positive charge.

Sodium forms ionic compounds with different anions, such as sulfate (SO4 2-) and chloride (Cl-).

In sodium sulfate (Na2SO4), sodium is still a cation with a charge of +1, while sulfate is an anion with a charge of -2.

In sodium chloride (NaCl), sodium is still a cation with a charge of +1, while chloride is an anion with a charge of -1.

Therefore, the cation that remained the same between sodium sulfate and sodium chloride is sodium (Na+).

Explanation:

Sodium (Na) is a cation, which means it has a positive charge.

Sodium forms ionic compounds with different anions, such as sulfate (SO4 2-) and chloride (Cl-).

In sodium sulfate (Na2SO4), sodium is still a cation with a charge of +1, while sulfate is an anion with a charge of -2.

In sodium chloride (NaCl), sodium is still a cation with a charge of +1, while chloride is an anion with a charge of -1.

Therefore, the cation that remained the same between sodium sulfate and sodium chloride is sodium (Na+). In chemistry, there are two types of ions: cations and anions.

Cations are ions that have a positive charge because they have lost one or more electrons. Anions are ions that have a negative charge because they have gained one or more electrons.

Sodium (Na) is a cation with a charge of +1, meaning it has lost one electron. In both sodium sulfate (Na2SO4) and sodium chloride (NaCl), sodium is still a cation with a charge of +1.

Therefore, the cation that remained the same between sodium sulfate and sodium chloride is sodium (Na+).

The cation (Na⁺) stayed the same in both cases, whereas the anions (SO₄²⁻ and Cl⁻) differed. The cation (Na+) remained the same in both cases, whereas the anions (SO₄²⁻ and Cl⁻) differed.

The ion that remained the same between sodium sulfate and sodium chloride is cation. An ion is an atom that has lost or gained one or more electrons. A positive ion is known as a cation since it has lost one or more electrons, whereas a negative ion is known as an anion since it has gained one or more electrons. The ions are crucial for the chemical reactions to occur and salt formation.

In sodium sulfate (Na2SO4), the sodium (Na) atom gives away two electrons to create Na+. In this example, the Na+ ion is formed, which is a cation. In sodium chloride (NaCl), the sodium (Na) atom gives away one electron to create Na+. In this example, the Na+ ion is also formed, which is a cation.

The cation (Na+) stayed the same in both cases, whereas the anions (SO₄²⁻  and Cl⁻) differed. As a result, the cation (Na+) remained the same in both cases, whereas the anions (SO₄²⁻  and Cl⁻) differed.

The major difference between heat transfer by conduction and convection and heat transfer by radiation is that heat transfer by conduction and radiation requires a material medium, while heat transfer by radiation is done by electromagnetic waves and doesn't require a medium.

Heat or thermal energy is the energy generated when atoms or molecules move in a variety of directions (translational, rotational and vibrational). The three methods of heat transfer are convection, conduction and radiation. Conduction only occurs between solid objects in contact, convection occurs within a fluid, and radiation occurs through electromagnetic waves.

Unlike conduction and convection, radiation doesn't require a material medium before heat is transferred, as electromagnetic radiations don't require a material medium to propagate. Heat is transferred by radiation through infrared rays. Other differences include:
