Why are a weak acid and the salt of its conjugate base used in preparing a buffer, rather than a strong acid and a salt of its conjugate base?.

Answers

An acid is more acidic than its conjugate base if its pKa value is less than or equal to seven prepared a buffer solution .

When making a buffer, why do you utilize a weak acid and the salt of its conjugate base?

A weak acid and its conjugate base are present in high amounts in buffer solutions (or a weak base and its conjugate acid). Buffers are extremely resistant to fluctuations in pH because these ingredients may neutralize extra H+ or OH.

Why is it necessary to create a buffer solution using both an acid and a base?

In buffers, basic species are present to neutralize H + ions and acidic species to do the opposite. These two species must, nevertheless, be able to coexist in a solution without fully negating one another.

Suppose 9.07 g of copper(II) nitrate is dissolved in 100. mL of a 0.70 M aqueous solution of sodium chromate the final molarity of copper(II) cation in the solution will be 0.48 M

The balanced equation is given as :

Cu(NO3)2 + Na2CrO4 = CuCrO4 + 2NaNO3

Number of mol of copper nitrate = mass /molar mass

                                                        = 9.07 g/187.5 g/mol

                                                        = 0.048 mol

mol sodium chromate = molarity x volume (L)

Answers

After a while at room temperature, a piece of dry ice, or solid CO2, vanishes without leaving a puddle of liquid behind.

What is solid CO2?

Dry ice, which is a solid form of carbon dioxide, is available. When used for short-term refrigeration, CO2 is usually used because it frequently sublimates from the solid form to the gas state due to the fact that it does not have a liquid state at normal atmospheric pressure. Carbon dioxide that is solid is known as "dry ice." Due to its ice-like appearance and the fact that it truly sublimes rather than melting, dry ice appears to be made of ice. Because the solid does not first become a liquid when heated, it is known as dry ice.

What is solid CO2 used for?

Dry ice, also known as solid carbon dioxide, is very cold (109 °F / 78 °C), and it is frequently used to cool vaccines, chill and freeze food, preserve blood and tissue samples, heat-treat metals, and even produce special effects like fog for events or stage plays.

Answers

This would be considered pseudoscience because all matter is made of atoms

The statement that "it is pseudoscience because ancient knowledge is mystical yet reliable" is the most appropriate explanation.

Alchemy is considered a pseudoscience. The statement that "all matter is composed of air, fire, earth, and water" is not consistent with our modern scientific understanding of matter. Alchemy was an ancient practice that attempted to transform base metals into noble metals (such as gold) and find a way to achieve eternal life, among other goals. While alchemy did contribute to the development of early chemistry and the discovery of some chemical processes, its beliefs and methodologies were often based on mystical and philosophical concepts rather than empirical scientific evidence.

In contrast, modern science understands that matter is composed of atoms and elements. The periodic table categorizes all known elements, and we have a comprehensive understanding of atomic structure and chemical reactions, which is not consistent with the alchemical view of matter being composed of air, fire, earth, and water.

Therefore, the statement that "it is pseudoscience because ancient knowledge is mystical yet reliable" is the most appropriate explanation. Alchemy is considered pseudoscience because its claims and theories were based on mystical and speculative beliefs rather than the systematic empirical observations and rigorous scientific methodology that characterize genuine scientific endeavors.

The ideal gas density depends on the molecular weight temperature and pressure of the system. Density is an important parameter in heat and mass transfer calculations. It is also used to derive many important dimensionless numbers such as the Reynolds number and the Peclet number.

Real gases approach ideal gas behavior at relatively low densities low pressures, and high temperatures. At high temperatures, the gas molecules have enough kinetic energy to overcome the intermolecular forces, but at low temperatures, the gas has less kinetic energy, so the intermolecular forces are more pronounced.

During which changes of state do atoms overcome the attractive forces between them?freezing and condensationboiling and depositioncondensation and meltingvaporization and sublimation.

Answers

Answer:

Vaporisation and Sublimation

Explanation:

Vaporisation is conversion of liquid to gas. Atoms in the liquid overcome forces of attraction to turn into gas.

Sublimation is direct conversion of solid to gas. Atoms in the solid directly convert into gas by overcoming forces of attraction.  E.g - Dry Ice

could you determine the molar mass of magnesium based on the total chloride ion concentration in the solution instead of using the amount hydrogen gas produced?

Answers

The ideal gas law and the gas mass are both used to determine the amount of hydrogen in moles. Learn about the ideal gas law, which is expressed as PV = nRT, where "P" stands for pressure, "V" for volume, "n" for the number of moles of a gas, and "T" for temperature.

The weight of one mole of a sample is known as the molar mass. To determine the molecular mass of a molecule, multiply the subscript (number of atoms) by the atomic mass of each element in the molecule, then add the masses of all the elements in the molecule together.

what species are made at the anode and cathode, respectively, during the electrolysis of molten kbr? a) br⁻(aq) and k⁺(aq) b) k(l) and br⁻(aq) c) br₂(g) and k(l) d) br₂(g) kbr(l) e) br⁻(aq) k(l)

Answers

Br₂(g) and K(l) species are made at the anode and cathode, respectively, during the electrolysis of molten kbr .

The term "electrolysis" describes the use of an electric current to break down a chemical. An illustration of this is the deposit of sodium and chlorine at various electrodes when the current is run through molten sodium chloride. Thus, sodium and chlorine are formed as sodium chloride breaks down. The cathode, also known as the positive or oxidizing electrode, is reduced during the electrochemical reaction after receiving electrons from the external circuit. Cations (positively charged ions) give rise to cathodes, while anions give rise to anodes. The cathode is the electrode that is negatively charged in an electrical device.

how many minutes will it take to plate out 2.19 g of chromium metal from a solution of cr3 using a current of 55.2 amps in an electrolyte cell?

Answers

3.69 minutes will be needed to plate the chromium metal in the solution.

The charge transfer amount may be provided by:

q = It

where I is the current, t is the time, and q is the charge transfer

Q can be calculated by:

Moles of Cr = 0.0423 mole; As, moles = 2.19/51.9

Also, there is transfer of 3 electrons, thus, charge transfer will be faraday constant multiplied by 3

Charge transfer = 0.0423 *3*  96500 C

Charge transfer = 12245.85 C

As, q = it

12245.85 = 55.2 * Time
