The equation that illustrates the relationship between wave velocity, frequency, and wavelength is: v = λ * f

v represents the wave velocity, which is the speed at which the wave travels through a medium. It is usually measured in meters per second (m/s).

λ (lambda) represents the wavelength of the wave, which is the distance between two consecutive points of similar phase on the wave. It is usually measured in meters (m).

f represents the frequency of the wave, which is the number of complete cycles or oscillations of the wave that occur in one second. It is usually measured in hertz (Hz).

The equation v = λ * f is known as the wave equation or the wave speed equation. It states that the wave velocity is equal to the product of the wavelength and the frequency of the wave.

This equation implies that as the frequency of a wave increases, the wavelength decreases, and vice versa, while keeping the wave velocity constant. In other words, if the frequency increases, the wave becomes more compressed and the distance between consecutive points of similar phase decreases.

On the other hand, if the frequency decreases, the wave becomes more spread out, and the distance between consecutive points of similar phase increases.

On average, a driver's side airbag can inflate to a volume of around 60 to 80 liters (16 to 21 gallons), while a passenger's side airbag can inflate to a volume of around 100 to 120 liters (26 to 32 gallons).

Explanation:

The reaction in an airbag involves several elements and compounds, including:

1. Sodium azide (NaN3): This is a primary component of the propellant used in most airbag systems. When heated, sodium azide decomposes into nitrogen gas (N2) and sodium metal.

2. Potassium nitrate (KNO3): This is another component of the propellant that provides additional oxygen to support the combustion of sodium azide.

3. Silica (SiO2): This is a common material used in the manufacture of airbag fabrics. When the airbag inflates, the silica particles in the fabric help to prevent the bag from tearing or puncturing.

4. Nitrogen gas (N2): This is the primary gas produced during the airbag reaction. The nitrogen gas is used to inflate the airbag quickly and provide a cushion between the vehicle occupant and hard surfaces.

5. Carbon dioxide (CO2): This is a secondary gas produced during the airbag reaction. The CO2 is produced as a result of the combustion of sodium azide and the reaction between sodium metal and water vapor present in the air.

From the prefix "macro" which means large, macromolecules are considered to be "large molecules" when compared to the micromolecules. They come in four major types: proteins, nucleic acids, carbohydrates and lipids.

These macromolecules have three common elements and these are: Carbon, Hydrogen and Oxygen. These are all essential in the vitality of life. The human body is said to have 10% of carbon and 63% oxygen. Hydrogen, on the other hand, is said to be the most abundant element among organic molecules.

The equilibrium constant kc equals 0.0085 for the following response at 89°C.  \(CH_{3} OH(g)\) ⇄  \(CO(g) +2H_{2} (g)\)  the value of the equilibrium constant (Kp) at 89°C is 0.016 \(atm^2\).

To find the relationship between the equilibrium constant Kc and the equilibrium constant Kp for a response,

we need to use the following equation:

Kp = \(Kc(RT)^{\delta\:n}\)

where R is the gas constant,

T is the temperature in Kelvin, and

\(\delta\:n\) shows the difference in the number of moles of gas between the products and the reactants.

For the given reaction, the balanced equation is as shown below:

\(CH_{3} OH(g)\) ⇄  \(CO(g) +2H_{2} (g)\)

The difference in the number of moles of gas  is calculated as:

\(\delta\:n\) = (1 + 2) - 1

\(\delta\:n\) = 2

where we count the coefficients of the gaseous products and deduct the coefficient of the gaseous reactant.

By placing the given values into the equation:

Kp = \(Kc(RT)^{\delta\:n}\)

Kp = \((0.0085) (0.0821\: L\:atm/mol\:K)^2 (362.15 K)\)

When struck with light of sufficient energy, some likely outcomes of the photochemical decomposition of silver chloride are:

1. Formation of silver (Ag) and chlorine (Cl2) - The silver chloride (AgCl) molecule absorbs the light energy, causing the bond between the silver and chlorine atoms to break. This results in the formation of silver (Ag) and chlorine (Cl2) gas.

2. Formation of a latent image in photography - In photography, the photochemical decomposition of silver chloride helps create a latent image. When the light-sensitive silver chloride layer on a film or photographic paper is exposed to light, the silver ions are reduced to metallic silver, forming a latent image that can be developed later with the appropriate chemicals.

840.12 mg of riboflavin was extracted when the weight of the cereal sample is 1.526 g and the volume is 40 ml.

To calculate the concentration of the riboflavin extraction solution in ppm, we need to first calculate the concentration of the solution in ppb using the fluorescence intensity measurement and the calibration curve equation.

Given:

The weight of the cereal sample = 1.526 g

The volume of water used for extraction = 40.0 mL

The volume of acetic acid used for extraction = 0.25 mL

Fluorescence intensity measured at 146.00 a.u.

Calibration curve equation: y = 6.40 × x + 26.7

First, we need to calculate the concentration of riboflavin in the extraction solution using the fluorescence intensity measurement:

146.00 a.u. = 6.40 × x + 26.7

Solving for x, we get:

x = (146.00 a.u. - 26.7) / 6.40

x = 20.89 ppb

Now, we can convert the concentration from ppb to ppm:

ppm = ppb × 1000

ppm = 20.89 ppb × 1000

ppm = 20,890 ppm

Therefore, the concentration of the riboflavin extraction solution is 20,890 ppm.

To calculate how many mg of riboflavin was extracted, we need to use the following formula:

Amount of riboflavin = concentration of riboflavin x volume of solution

The volume of the extraction solution is 40.0 mL + 0.25 mL = 40.25 mL.

To convert the volume to liters:

Volume of solution = 40.25 mL ÷ 1000 mL/L = 0.04025 L

Now we can substitute the values into the formula:

Amount of riboflavin = 20,890 ppm x 0.04025 L

Amount of riboflavin = 840.12 mg

Here are the steps in the mechanisms for a) saponification of ethyl benzoate and b) ammonolysis of ethyl benzoate:
Saponification of ethyl benzoate:  The ethyl benzoate reacts with a strong base, such as sodium hydroxide (NaOH), in the presence of water (H2O).

The strong base (NaOH) deprotonates the ethyl benzoate by abstracting a proton from the carboxylic acid group. This forms the corresponding carboxylate anion and ethanol as a byproduct. The carboxylate anion then reacts with the hydroxide ion (OH-) from the base to form a salt known as sodium benzoate. This reaction is called saponification because it produces a soap-like substance.

The ethanol produced in step 2 may further react with the base to form sodium ethoxide and water.
Overall, the saponification of ethyl benzoate produces sodium benzoate and ethanol as the main products. Ammonolysis of ethyl benzoate: The ethyl benzoate reacts with ammonia (NH3) in the presence of a catalyst, such as an acid or base.

The volume of 0.140 M NaOH required to reach the equivalence point in the titration of 40.0 mL of 0.100 M HNO₃ is 28.6 mL.

To calculate the volume of NaOH to reach the equivalence point in the titration of HNO₃, we must write the balanced chemical equation is:

HNO₃(aq) + NaOH(aq) → NaNO₃(aq) + H₂O(l)

In the reaction between HNO₃ and NaOH, 1 mole of NaOH reacts with 1 mole of HNO₃. So, the number of moles of NaOH required to neutralize 1 mole of HNO₃ is 1.

According to the question, the volume of HNO₃ is 40.0 mL and the concentration of HNO₃ is 0.100 MM. To calculate the number of moles of HNO₃:

molarity = number of moles / volume (in L)

number of moles = molarity × volume (in L)

number of moles of HNO₃ = 0.100 M × (40.0 mL / 1000 mL/L)

= 0.00400 moles

Now, as 1 mole of NaOH reacts with 1 mole of HNO3, so 0.00400 moles of NaOH are required to react with HNO₃.

According to the question, the concentration of NaOH is 0.140 M. So, to calculate the volume of NaOH required:

moles of NaOH = molarity × volume (in L)

volume (in L) = moles of NaOH / molarity

volume of NaOH = 0.00400 moles / 0.140 M

= 0.0286 L = 28.6 mL
