It would take a banana slug approximately 1,029,863 minutes to run a complete marathon, which is equivalent to about 17,164 hours or approximately 714 days.

To determine the length of time it would take for a banana slug to run a complete marathon of 26.2 miles, use the given information and conversion factors:

Given:

Slug Travel Rate: 0.0229 mm/s

Conversion Factors:

1 mile = 5280 feet

1 foot = 12 inches

1 inch = 2.54 cm

1 cm = 10 mm

1 second = 1 s

Now set up the conversions to cancel out the units and find the time:

26.2 miles × (5280 feet/1 mile) × (12 inches/1 foot) × (2.54 cm/1 inch) × (10 mm/1 cm) × (1 s/0.0229 mm) = X seconds

Calculating this value:

X = (26.2 × 5280 × 12 × 2.54 × 10) / (0.0229)

X ≈ 61,791,789.68 seconds

Now convert seconds to a time unit that has a value between 1 and 100. Let's choose minutes:

61,791,789.68 seconds × (1 min / 60 seconds) = Y minutes

Y ≈ 1,029,863.16 minutes

So, it would take a banana slug approximately 1,029,863 minutes to run a complete marathon, which is equivalent to about 1,029,863/60 ≈ 17,164 hours or approximately 714 days.

Explanation:

First thing to do here is to calculate the molar mass of the compound

Mathematically;

molar mass = mass/number of moles

we can calculate the number of moles using the ideal gas equation

Mathematically;

PV = nRT

n = PV/RT

where p is the pressure at 5 atm

V is the volume at 568 ml = 568/1000 = 0.568 L

R is the molar gas constant which is 0.0821

T is the temperature which is 120+ 273 = 393k

Inserting these values into the equation, we have

n = (5 * 0.568)/(0.0821 * 393)

n = 0.088 moles

So the molar mass = 10/0.088

= 114 g/mol

Now let’s go to the percentages

C = 84.2/12 = 7.016666666666667

H = 15.8/1 = 15.8

divide by the smallest

C = 7.016666666666667/7.016666666666667 = 1

H = 15.8/7.016666666666667 = 2 approximately

The empirical formula is CH2

So for the molecular formula, we have;

(12 + 2)n = 114

14n = 114

n = 114/14 = approximately 8

So the molecular formula of the liquid will be (CH2)n = C8H16

In the case of the equilibrium reaction provided, if the concentration of Co(H2O)2+ is increased, the reaction will shift to the right in order to consume the excess Co(H2O)2+ and produce more CoCl2 and H2O.

Conversely, if the concentration of CoCl2 is increased, the reaction will shift to the left in order to consume the excess CoCl2 and produce more Co(H2O)2+ and Cl- ions.

According to Le Chatelier's principle, a change in concentration of one or more of the reactants or products of a chemical reaction at equilibrium will cause a shift in the equilibrium position to counteract the change and re-establish equilibrium.

Specifically, if the concentration of one of the reactants is increased, the reaction will shift in the direction that consumes that reactant in order to restore equilibrium.

The order of increasing rate of effusion is: C₂H₆ < PH₃ < HCl < Ar.

The rate of effusion for a gas depends on its molar mass and the temperature. According to Graham's law of effusion, the rate of effusion is inversely proportional to the square root of the molar mass. Therefore, gases with lower molar masses will effuse faster than those with higher molar masses at the same temperature.

To arrange the gases in order of increasing rate of effusion, we need to compare their molar masses:

Ar (argon): Molar mass = 39.95 g/mol

HCl (hydrogen chloride): Molar mass = 36.46 g/mol

PH₃ (phosphine): Molar mass = 33.99 g/mol

C₂H₆ (ethane): Molar mass = 30.07 g/mol

Now, we can compare the molar masses and determine the order of increasing rate of effusion:

C₂H₆ (ethane): It has the lowest molar mass among the given gases, so it will have the highest rate of effusion.

PH₃ (phosphine): It has a higher molar mass than ethane but lower than hydrogen chloride and argon. Therefore, it will have a higher rate of effusion compared to hydrogen chloride and argon but lower than ethane.

HCl (hydrogen chloride): It has a higher molar mass than both ethane and phosphine. Hence, it will have a lower rate of effusion than ethane and phosphine.

Ar (argon): It has the highest molar mass among the given gases, so it will have the lowest rate of effusion.

Therefore, the order of increasing rate of effusion is:

C₂H₆ < PH₃ < HCl < Ar

In summary, ethane (C₂H₆) will have the highest rate of effusion, followed by phosphine (PH₃), hydrogen chloride (HCl), and finally, argon (Ar), which will have the lowest rate of effusion.

Total, 561 grams of diphosphorus trioxide are required to produce 10.2 moles of phosphorous acid.

The balanced chemical equation for the reaction between diphosphorus trioxide and water to produce phosphorous acid is;

P₂O₃ + 3H₂O → 2H₃PO₃

From this equation, we can see that 1 mole of P₂O₃ produces 2 moles of H₃PO₃.

Therefore, the number of moles of P₂O₃ required to produce 10.2 moles of H₃PO₃ is;

10.2 moles H₃PO₃ × 1 mole P₂O₃/2 moles H₃PO₃ = 5.1 moles P₂O₃

To convert from moles to grams, we need to use the molar mass of P₂O₃, which is;

2 × atomic mass of P + 3 × atomic mass of O = 2 × 31.0 g/mol + 3 × 16.0 g/mol = 110.0 g/mol

Therefore, the mass of P₂O₃ required is;

5.1 moles P₂O₃ × 110.0 g/mol = 561 g

Therefore, 561 grams of P₂O₃ is required.

The approximate pH at the equivalence point of a weak acid-strong base titration if 25 ml of aqueous hydrofluoric acid requires 30.00 ml of 0.400 m NaOH is 0.66.

We must first figure out how many moles of NaOH were supplied to achieve the equivalence point in a weak acid-strong base titration before we can determine the pH there.

Molarity times volume is 0.400 mol/L times 0.03000 L, or 0.0120 mol of NaOH.

NaOH and HF have a 1:1 stoichiometric ratio, therefore 0.0120 mol of HF is also how many moles were in the initial solution.

We can now calculate HF's Ka using the equilibrium formula for HF:

Ka = [HF][H+][F-]

All of the HF's reactions with the NaOH at the equivalence point have produced water and NaF.

The pH at the equivalency point is as a result:

pH is almost equal to -log[H+] = -log (0.220) = 0.66 (to two significant figures).

The acid dissociation constant (Ka) for uric acid is \(1.0 x 10^-5.\)

The dissociation of uric acid can be represented as follows:

H2UA ⇌ H+ + HUA

The equilibrium expression is given by:

Ka = [H+][HUA-]/[H2UA]

where Ka is the acid dissociation constant, [H+] is the concentration of hydrogen ions, [HUA-] is the concentration of the urate ion, and [H2UA] is the concentration of uric acid.

At equilibrium, the concentration of H2UA is equal to the initial concentration minus the concentration of H+ ions that have been consumed:

[H2UA] = 0.110 - [H+]

The concentration of HUA- can be calculated from the equation:

[HUA-] = [H+]

Substituting the above expressions into the equilibrium expression for Ka, we get

\(Ka = ([H+]^2) / (0.110 - [H+])\)

Substituting [H+] = 3.4 x 10^-2 M, we get:

\(Ka = [(3.4 x 10^-2)^2] / (0.110 - 3.4 x 10^-2)\)

\(Ka = 1.0 x 10^-5\)

Therefore, the acid dissociation constant (Ka) for uric acid is \(1.0 x 10^-5.\)

D. The chances of forming a permanent dipole increases down the group, and this increases the strength of the intermolecular forces.

                                              D is incorrect

The boiling point increase down a group because the total number of electrons increases down the group, and this increases the strength of the intermolecular forces. Hence option C is correct.

Boiling point of a substance is the temperature at which the substance changes from its liquid state to vapour state. Boiling point of a molecule or compounds depends on the bond type, molecular weight, temperature and pressure.

For ionic compounds, boiling point will be higher since ionic bonds are stronger than covalent compounds. There is a periodic trend for the physical properties such as boiling point for elements in periodic table.

Down a group, the number of electrons increases and the atomic size also as well as the ionic character increases down a group . These two facts leads to higher intermolecular attraction, thus more temperature have to applied to weaken the bonds.

Higher temperature to be applied means the boiling point of the substance is higher. Therefore, boiling point down a group increases because of the higher intermolecular attraction as said in option C.

The statement, that describes potential benefit of using nuclear fusion to produce electricity is "no carbon emission, production of less radioactive waste and energy efficiency."

Nuclear fusion is the process by which two light atomic nuclei merge to produce a single heavier one, releasing huge quantities of energy in the process. Fusion power is a suggested method of generating electricity by utilising heat from nuclear fusion processes.

Fusion reactors, unlike fission reactors, cannot sustain a chain reaction and so can never melt down.

If the correct atoms are used, the fusion reaction creates very little or no radioactive waste. Small amounts of helium, an inert gas that can be safely released without hurting the environment or energy efficiency, are the only byproducts of fusion processes. Less radioactive waste is produced during the fusion process. The fusion reactant is more widely available.
