Answer:

the new volume is 1.35L

Explanation:

The computation of the new volume in the case when the temperature rises to 45 degrees is shown below:

GIven that

Volume = 1.25L

And, the temperature is 22 degrees celsius

So, \(T_1\) = (275 + 22)k

= 297 k

Now

\(T_2\) = (275 + 45)k

= 320 k

Now as it is a constant pressure

So, the new volume is

\(\frac{V_1}{T_1} = \frac{V_2}{T_2} \\\\V_2 = \frac{V_1}{T_1}\times T_2 \\\\= \frac{1.25}{297}\times 320\)

= 1.35L

hence, the new volume is 1.35L

Explanation:

The reaction between magnesium ribbon and dilute hydrochloric acid is a classic example of a single replacement reaction, which can be represented by the following chemical equation:

Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g)

In this reaction, magnesium (Mg) reacts with hydrochloric acid (HCl) to form magnesium chloride (MgCl2) and hydrogen gas (H2).

The rate of this reaction can be altered by changing the concentration of the hydrochloric acid. This is because the rate of a chemical reaction depends on the concentration of the reactants. Specifically, the rate of the reaction is proportional to the concentration of the reactants raised to some power, which is determined by the reaction's rate law.

In this reaction, the rate law can be expressed as:

Rate = k [Mg] [HCl]^x

Where k is the rate constant and x is the order of the reaction with respect to hydrochloric acid. The order of the reaction with respect to magnesium is one, since the concentration of magnesium does not change during the reaction.

When the concentration of hydrochloric acid is increased, the rate of the reaction increases because there are more hydrochloric acid molecules available to collide with magnesium atoms and react. This means that the value of x is greater than zero and the reaction is dependent on the concentration of hydrochloric acid.

Conversely, when the concentration of hydrochloric acid is decreased, the rate of the reaction decreases because there are fewer hydrochloric acid molecules available to react with magnesium. This means that the value of x is less than one and the reaction is not entirely dependent on the concentration of hydrochloric acid.

Thus mass of dye A = 10.24 mg/L

Plot Beer-Lambert law

Beer-Lambert law states that absorbance of an analye (here, dye A) is directly proportional to its concentration (C) and pathlength (l) of the solution

i.e. A \propto  C*l

or A = \epsilonCl

where \epsilon = proportionality constant and is called absorptivity coefficient. It is characteristic for an analyte at a given wavelength, unit = M-1cm-1

Thus above equation can be compared with a straight line equation as y = mx+c

where y = absorbance, x = concentration and \epsilon = slope, c = intercept = 0 for absorbance vs concentration plot.

b. Calculate the slope (m) of graph:

for absorbance vs concentration plot.

The given data was plotted and fitted to a liner fit that gave the equation as:

y = 27335 x

slope of the line = 27335

thus \epsilon = 27335 M-1cm-1

c. Concnetration using Beer-Lambert plot:

Absorbance of dye A in Sports drink, A = 0.700

point absorbance of 0.007 on y-axis and interpolate to the linear fit. Check the corresponding value at x-axis as follows:

the corresponding line meets x-axis at 0.00002 + 4-squares

In the graph drawn, 7 squares in x-axis = 0.00001

thus 4 squares on x-axis = 0.00001*4/7 = 5.71*10-6

thus for y = 0.700 the corresponding x-axis reads = 0.00002+5.71*10-6

or C = 2.57*10-5 M

d. Concnetration of dye A using slope of fitted line:

Absorbance of dye A in Sports drink, A = 0.700

substituting the absorbance in the linear fit equation we can calulate the concentration as:

0.700 = 27335*C

C = 0.700/27335

C = 2.56*10-5 M

e. Mass of dye A in mg/L

Molar mass of dye = 400 g/mol

Concentration (molarity) of dye A = 2.56*10-5 M

1 M = number of moles of solute present in 1 L of solution volume

number of moles = mass / molar mass

\therefore  Molarity = mass of solute/(molar mass of solute*volume of solution)

for solution volume = 1L

Molarity = mass of solute/molar mass of solute

rearranging this we get:

mass of solute = (Molarity*molar mass of solute) g/L

mass of dye A = 2.56*10-5* 400 g/L

m = 0.01024 g/L

1 g = 1000 mg

The situation which would have caused the clear yellow solution to remain as is in dibenzalacetone synthesis at the end of 30 minutes can be due to Insufficient reactants, Inappropriate reaction conditions and Inhibition of the reaction.

The starting materials of dibenzalacetone synthesis are all colorless and turn into a clear yellow solution as they are mixed. The situation that would have caused the clear yellow solution to remain as is at the end of 30 minutes is the reaction having gone to completion. The formation of dibenzalacetone involves the aldol condensation of two moles of benzaldehyde with one mole of acetone.

The reaction is carried out in the presence of a base such as NaOH, which removes the acidic alpha-hydrogens of benzaldehyde and acetone to form the enolate ions. These ions are then condensed to form dibenzalacetone. In a successful reaction, the clear yellow solution will eventually become cloudy as dibenzalacetone forms as a solid precipitate. This can occur if not all of the starting materials were properly mixed or if the reaction did not proceed to completion due to factors such as insufficient heating or the presence of impurities.

Insufficient reactants: If there are not enough starting materials present, the reaction may not proceed to completion, and the yellow solution will not change. Inappropriate reaction conditions: Factors such as temperature, solvent, or pH could affect the reaction. If any of these factors are not optimal, the reaction may not proceed efficiently, leading to an unchanged yellow solution.

Inhibition of the reaction: The presence of any impurities or contaminants in the starting materials or the reaction mixture could potentially inhibit the reaction, causing the yellow solution to remain unchanged. To address these situations, ensure that you have the correct amounts of starting materials, follow the recommended reaction conditions, and work with clean and pure chemicals and equipment.

For filtering particles from a 180°F gas stream containing ammonia, a suitable fabric would be PTFE (Polytetrafluoroethylene). For the 250°F gas stream containing SO₂, a suitable fabric would be P84 (Polyimide).

When dealing with a 180°F gas stream containing ammonia, PTFE fabric is a good choice due to its excellent chemical resistance and high-temperature stability. PTFE is known for its nonstick properties and resistance to a wide range of chemicals, including ammonia. It can withstand high temperatures and is capable of filtering out particles effectively.

In the case of a 250°F gas stream containing SO₂, P84 fabric is a suitable option. P84, a polyimide-based fabric, exhibits excellent resistance to acids, alkalis, and organic solvents, making it suitable for environments containing SO₂. It has good thermal stability, allowing it to withstand the high temperatures of the gas stream. P84 fabric also has a high filtration efficiency and can effectively capture fine particles.

Both PTFE and P84 fabrics are commonly used in industrial filtration applications due to their chemical resistance, high-temperature stability, and efficient particle filtration capabilities. However, it's important to consider specific operating conditions, such as gas composition, temperature, and other factors, to ensure the chosen fabric is compatible and optimized for the intended application.

        Volatile Organic Compounds are present in a large number of commonly used professional spray paints (VOCs). VOCs are a group of compounds that are released as gases from a range of solids and liquids, some of which may be harmful to human health in the short- and long-term.

        When a valve button is depressed, aerosol paint, also known as spray paint, is released from a sealed, pressurized container in an aerosol spray. One type of spray painting is aerosol painting, which leaves a smooth, even coat in contrast to many conventional rolled and brushed paints.

         Not every change in color results from a chemical shift. If one were to alter a substance's color through a non-chemical interaction, such as painting an automobile, the alteration would be physical rather than chemical.

        Spray paints come in aerosol cans and are liquid paints. The top of a can  of spray paint has a button that, when depressed, releases paint. Compressed gas is used in aerosol spray cans as a liquid propellant.

          A million times faster than brush-on paint is spray paint. Since spray paint is often oil based rather than water based, it is more durable than conventional latex paint or spray paint. Using spray paint outside is simple when you have a drop cloth and some newspaper handy.

Hence, CO₂ is the limiting reagent and the excess reagent. Because 24.5 g CoO produces more urea than 654 moles Co₂o₃. 2.58 g O₂,  is the excess reagent and CO₂O₃ is the limiting reagent. The rate of photosynthesis is greatly influenced by carbon dioxide. The amount of CO₂ in the atmosphere is relatively low.

The coefficients of CoO and O2 must be multiplied by 3 and 2, respectively, in order to balance the equation:

To find the greatest mass of Co2O3 that can be created, we can now apply stoichiometry:

The masses of CoO and O₂ must first be converted to moles: Moles of CoO are equal to 24.5 g/654 mol. O₂ moles are equal to 2.58g / 161 mol. The balanced equation can then be used to get the mole ratio of CoO to Co₂O₃

The mole ratio is: thus 3 moles of CoO yield 1 mole of

Moles of Co₂O₃ are equal to (0.147 mol CoO) / 3 (0.049 mol).

The moles of can finally be changed to grammes as follows:
