By using pH formula, the concentration of hydroxyl ion [OH-] will be 5.3 ×\(10^{-4}\) M.

What is pH?

The pH scale is a measurement of hydrogen ion concentration that is used to determine the acidity as well as alkalinity of a solution.

Calculation of [OH-] by using formula of pH.

Given data:

[H+] = 1.87 x \(10^{-11} M\)

[OH-] = ?

Calculation of [OH-] is shown below:

It can be calculated by using the formula:

pH = -log [H+]

Put the value of concentration of hydrogen ion [H+]  in above formula.

pH = -log (1.87 x \(10^{-11} M\))

pH = -log (1.87) -log ( \(10^{-11} M\))

pH = -0.27 +11

pH = 10.73

Now, use the formula, pH +pOH = 14

pOH = 14 - pH

pOH = 14 - 10.73

pOH = 3.27

Now, use formula pOH = -log [OH-]

[OH-] = \(10^{-pOH}\)

[OH-] = \(10^{-3.27}\)

[OH-] = 5.3 ×\(10^{-4}\) M

Therefore, the concentration of hydroxyl ion [OH-] will be 5.3 ×\(10^{-4}\) M.

For 6 electron domain systems, the two sets of lone pairs are placed in the axial positions. This arrangement helps to minimize electron repulsion and achieve maximum stability. By placing the lone pairs in the axial positions, they are positioned as far apart as possible from each other and from the bonded atoms, reducing the repulsive interactions.

In a 6-electron domain system, such as a molecule with a trigonal bipyramidal or octahedral geometry, the axial positions refer to the positions along the axis perpendicular to the equatorial plane. The equatorial positions are occupied by the bonded atoms.

The placement of lone pairs in the axial positions allows for a more favorable distribution of electron density, contributing to the overall stability and geometry of the molecule.

Explanation:

When we say anything is a wave, what exactly do we mean? The most intuitive and straightforward wave to envision is a water wave. A motion, more specifically, is a disturbance that propagates or travels away from its source. Water waves are caused by a disruption in the water's surface, such as a rock tossed into a pond or a swimmer splashing the surface continuously. The noise for sound waves is a rise of air pressure, which may be caused by the oscillating cone within a speaker. There are many kinds of disturbances in earthquakes, including surface disturbances and pressure disturbances under the surface. Even radio signals are best deciphered by using a comparison of sea waves Water waves are helpful to visualize since they are more than just a mental picture. The amplitude, period, frequency, and energy of water waves are all the same as they are for all waves. A small set of underlying principles can be used to describe all wave characteristics.

Explanation:

Decomposition reaction, also known as analysis or dissociation, is a type of chemical reaction in which a compound breaks down into simpler substances or elements. In this reaction, a single reactant undergoes a chemical change and produces two or more products.

The decomposition reaction can be represented by the general equation:

AB → A + B

Where AB is the reactant, and A and B are the products. The reactant AB is usually a compound, and it breaks down into its constituent elements or simpler compounds.

There are different types of decomposition reactions, including:

Thermal decomposition: It occurs when a compound is heated, resulting in its decomposition into simpler substances. For example, the thermal decomposition of calcium carbonate (CaCO3) produces calcium oxide (CaO) and carbon dioxide (CO2):

CaCO3 → CaO + CO2

Electrolytic decomposition: It takes place when an electric current is passed through an electrolyte, causing it to break down into its component ions. For instance, the electrolysis of water (H2O) leads to the decomposition into hydrogen gas (H2) and oxygen gas (O2):

2H2O → 2H2 + O2

Photochemical decomposition: It occurs when a compound undergoes decomposition due to exposure to light energy. Chlorine gas (Cl2) can decompose into chlorine atoms (Cl) under the influence of light:

Cl2 → 2Cl

These are just a few examples of decomposition reactions. They are important in various chemical processes and are used in industries, laboratory experiments, and natural phenomena. By understanding and controlling decomposition reactions, scientists can gain insights into the behavior of different compounds and develop practical applications in fields such as chemistry, materials science, and environmental science.

Adding Cs2SO3, which will quickly dissolve in the solution, would increase the buffer capacity of the 1.00L aqueous solution containing Na2SO3.

Buffer capacity is a measure of the ability of a solution to resist changes in pH when an acid or base is added. It depends on the concentrations of the buffering components in the solution. In this case, the solution contains Na2SO3, which acts as a buffer.

By adding Cs2SO3, which will quickly dissolve in the solution, we are increasing the concentration of the buffering component (SO3^2-) in the solution. This increase in the concentration of the buffering component leads to an increase in the buffer capacity of the solution.

Diluting the solution with water would decrease the concentration of the buffering component, resulting in a decrease in buffer capacity. Adding KHSO3 would introduce a different buffering component, but it may or may not increase the buffer capacity depending on the specific concentrations and properties of the components. Adding excess NaOH would neutralize any H2SO3 present and disrupt the buffering system, leading to a decrease in buffer capacity.

To increase the buffer capacity of the 1.00L aqueous solution containing Na2SO3, the recommended action is to add Cs2SO3, which will quickly dissolve in the solution. This increases the concentration of the buffering component and enhances the solution's ability to resist changes in pH.

Aseptic processing is a technique used in food production that involves sterilizing the packaging and food separately and then packaging the food in a sterile environment. This method is designed to maintain the quality and safety of food products by minimizing the risk of contamination with harmful microorganisms.

In aseptic processing, the food is first heat-treated or otherwise sterilized to eliminate any potential pathogens. This process also helps to extend the shelf life of the product without the need for chemical preservatives. Meanwhile, the packaging materials are also sterilized to ensure that they are free from any contaminants.

Once both the food and the packaging are sterilized, they are brought together in a controlled environment where strict hygiene standards are maintained. This ensures that the food remains uncontaminated during the packaging process. The sealed packages are then ready for distribution and can be stored without refrigeration, depending on the specific product.

Aseptic processing is different from other food preservation techniques, such as drying foods to decrease water content, adding chemical preservatives, or quickly freezing a food product after it is prepared. While these methods can also help maintain food quality and safety, aseptic processing offers a unique advantage in that it allows for longer shelf life without the need for refrigeration or added preservatives.

In summary, aseptic processing is a food preservation technique that involves sterilizing food and packaging separately and then combining them in a sterile environment. This method helps maintain food quality and safety, as well as extend shelf life without the use of chemical preservatives or refrigeration.

Answer:

The mass percentage of iron in \(\rm K_3[Fe(CN)_6]\)  (potassium ferricyanide) is approximately \(17\%\).

Explanation:

Start by finding the formula mass of potassium ferricyanide, \(\rm K_3[Fe(CN)_6]\), using relative atomic mass data from the question:

\(\begin{aligned} & M(\mathrm{K_3[Fe(CN)_6]}) \\ &\approx 3 \times 39 + 56 + 6 \times (12 + 14) \\ &= \rm 329 \; g \cdot mol^{-1}\end{aligned}\).

In other words, every one mole of \(\rm K_3[Fe(CN)_6]\) formula units have a mass of approximately \(329\; \rm g\).

On the other hand, note that there is one iron \(\rm Fe\) atom in every one mole of \(\rm K_3[Fe(CN)_6]\) formula units. Hence, there would be exactly one mole of iron atoms in every one mole of \(\rm K_3[Fe(CN)_6]\) formula units. The mass of that one mole of iron atoms is approximately \(56\; \rm g\) (again, from the relative atomic mass data of the question.)

Therefore:

\(\begin{aligned}& \text{Mass percentage of $\mathrm{Fe}$ in $\mathrm{K_3[Fe(CN)_6]}$} \\ &= \frac{\text{Mass of $\mathrm{Fe}$ in one mole of $\mathrm{K_3[Fe(CN)_6]}$ formula units}}{\text{Mass of one mole of $\mathrm{K_3[Fe(CN)_6]}$ formula units}}\times 100\% \\ &= \frac{M(\mathrm{Fe}) \times (\text{Number of $\mathrm{Fe}$ atoms in each $\mathrm{K_3[Fe(CN)_6]}$ formula unit)}}{M(\mathrm{K_3[Fe(CN)_6]})} \times 100\%\end{aligned}\)

\(\begin{aligned}&\approx \frac{1 \times 56\; \rm g \cdot mol^{-1}}{329\; \rm g \cdot mol^{-1}}\end{aligned}\).
