Explain how the compression factor varies with pressure and temperature and describe how it reveals information about the intermolecular interactions in real gases.

The concentration of H+ and OH- ions in a neutral solution is 1.0 × 10−7M

At 25°C, Kw = [H+][OH−] = 1.0 × 10−14.

For a neutral solution, the concentration of H+ and OH− ions is equal.

To find their concentrations, we'll use the formula Kw = [H+][OH−].

Since it is a neutral solution, H+ ion concentration equals OH- ion concentration.

[H+]= xM[OH-]=xMx²

=Kw = 1.0 × 10−14x

=sqrt(Kw) = 1.0 × 10−7[H+]

=[OH-]=1.0 × 10−7M

Note: The square root of Kw is called the ion product constant of water, and it equals 1.0 × 10−7 M.

So, the concentration of H+ and OH- ions in a neutral solution is 1.0 × 10−7 M. However, we can also express this using scientific notation as [H+]=1.0 × 10−7M and [OH−]=1.0 × 10−7M respectively.

Answer:

Its A

Explanation:

Just took the test and got a 100%

Answer:

A

Explanation:

Electrolysis has to do with the decomposition of a solution by the passage of direct current through it. Current enters and leaves the electrolyte via electrodes.

The positive electrode is called the anode while the negative electrode is called the cathode. Positive ions move towards the cathode while negative ions move towards the anode.

Cu^2+ moves towards the cathode and accepts two electrons to be deposited on the cathode as metallic copper. Also, Cl^- ions move towards the anode and gives up electrons to become oxidized to chlorine gas.

Hence in the electrolysis of CuCl2, copper is obtained at the cathode while chlorine gas is obtained at the anode. Hence 1 and 3 are correct statements.

Answer:

9.90

Explanation:

Given [H+] = 1.25 x 10^-10 M, we can calculate the pH using the formula:

pH = -log10([H+])

pH = -log10(1.25 x 10^-10)

Using logarithmic properties:

pH = -log10(1.25) - log10(10^-10)

Since log10(10^-10) is equal to -10:

pH = -log10(1.25) - (-10)

pH = -log10(1.25) + 10

Now, evaluating the logarithm using a calculator:

pH = -0.0969 + 10

pH = 9.9031

Therefore, the pH of the solution with [H+] = 1.25 x 10^-10 M is approximately 9.9031. Rounding it to two decimal places, the pH is approximately 9.90.

Answer:

Avogadro's law.

Explanation:According to Avogadro's law,at constant temperature and pressure,the volume of gas is directly proportional to the number of moles of the gas.

    This is not exactly a answer you can use but this is some information that you can use to find out the answer.

    You can usually confirm the charge associate degree particle unremarkably has by the element's position on the periodic table: The alkali metals (the IA elements) lose one negatron to create a ion with a 1+ charge. The alkaline-earth metal metals (IIA elements) lose 2 electrons to create a 2+ ion.

    Nonmetals type negative ions (anions). A range 7|chemical element|element|gas} atom should gain 3 electrons to possess an equivalent number of electrons as AN atom of the subsequent gas, neon. Thus, a gas atom can type AN ion with 3 additional electrons than protons and a charge of 3−.

Answer: Based on the stoichiometry 1 mole of carbon disulfide will produce 1 mole of carbon dioxide. Similarly we can apply the volume ratio, so 1.1L of carbon disulfide will produce 1.1L of carbon dioxide.

The Iterative design is a circular design process which comprises of models that are regularly evaluated and improved  based on the results of testing of previous models or versions.

Hence, when the company is involved in developing a new version of the carbon monoxide detector by evaluating the older  versions and continue testing each new version, they are involved in the circular process of iterative design.

The Ka value for benzoic acid (HC6H5COOH) is approximately 6.46 x 10^(-5) at 25°C.

To calculate the Ka value for benzoic acid, we need to use the pH and the initial concentration of the acid. The dissociation of benzoic acid in water can be represented by the equation: HC6H5COOH ⇌ H+ + C6H5COO-

The equilibrium expression for this reaction is: Ka = [H+][C6H5COO-] / [HC6H5COOH]

Given that the pH of the solution is 2.78, we can calculate the concentration of H+ ions using the equation: [H+] = 10^(-pH)

[H+] = 10^(-2.78) = 1.68 x 10^(-3) M

Since benzoic acid is a weak acid, we can assume that the concentration of C6H5COO- ions is approximately equal to the concentration of H+ ions.

Now, we need to determine the initial concentration of benzoic acid. It is given that 0.541 g of benzoic acid is dissolved in 100 mL of water. To convert this to molarity (M), we use the formula:

Concentration (M) = mass (g) / molar mass (g/mol) / volume (L)

The molar mass of benzoic acid (C6H5COOH) is 122.12 g/mol.

Concentration = 0.541 g / 122.12 g/mol / 0.1 L = 0.443 M

Now, substitute the values into the equilibrium expression:

Ka = (1.68 x 10^(-3) M)(1.68 x 10^(-3) M) / 0.443 M = 6.46 x 10^(-5)

The Ka value for benzoic acid at 25°C is approximately 6.46 x 10^(-5). This indicates that benzoic acid is a weak acid, as its Ka value is relatively small compared to strong acids.

There are 14.03 grams of KOH present per d\(m^{3}\) of solution.

To find the mass of KOH present per d\(m^{3}\), we need to use the molarity of the solution and the molar mass of KOH.

The molar mass of KOH is 56.11 g/mol.

We know that the solution has a molarity of 0.25M, which means there are 0.25 moles of KOH per liter of solution.

To find the mass of KOH per d\(m^{3}\)(which is the same as per liter), we can multiply the molarity by the molar mass:

0.25 mol/L x 56.11 g/mol = 14.03 g/L

Therefore, there are 14.03 grams of KOH present per d\(m^{3}\) of solution.
