Answers

Answer 1

The ranking from lowest boiling point to highest boiling point is (1) 0.10 m NaCl, (2) 0.10 m Al(NO3)3, (3) 0.30 m C12H22O11 (sucrose).

The boiling point of a solution is directly related to the solution's vapor pressure. This is due to the fact that, as the vapor pressure of the solution increases, the boiling point of the solution will also increase. The vapor pressure of a solution is a function of its concentration, so the higher the concentration of a solution, the higher its vapor pressure. Thus, the higher the concentration of a solution, the higher its boiling point.

Therefore, the correct order, from lowest to highest boiling point, is: (1) 0.10 m NaCl, (2) 0.10 m Al(NO3)3, (3) 0.30 m C12H22O11 (sucrose).

Radioactive decay follows first-order kinetics. If sodium-24 has a half-life of 14.96 hours, what is its rate constant, k?a. 4.63 × 10^−2 hr−1b. 4.36 × 10^−2 hr−1c. 4.93 × 10^−2 hr−1

Answers

If sodium-24 has a half-life of 14.96 hours then rate constant K is 0.0463 hr²−1 Rounded to two significant figures, the answer is (a) 4.63 × 10²−2 hr²−1.

The first-order rate equation is given by:

ln(N_t/N_0) = -kt

where N_0 is the initial amount of the substance, N_t is the amount of substance at time t, k is the rate constant, and ln is the natural logarithm.

The half-life of sodium-24 is given as 14.96 hours, which means that after 14.96 hours, the amount of sodium-24 will be reduced to half of its initial amount. Therefore, we can write:

N_t = (1/2)N_0

Substituting this into the first-order rate equation, we get:

ln(1/2) = -k(14.96)

Solving for k, we get:

k = [ln(1/2)]/14.96

k ≈ 0.0463 hr²−1

Therefore, the rate constant for the radioactive decay of sodium-24 is approximately 0.0463 hr²−1. Rounded to two significant figures, the answer is (a) 4.63 × 10²−2 hr²−1.

Place the following in order of increasing metallic character. Rb Cs K Na

Answers

The order of the following metallic characters: Na, K, Rb, Cs
The metallic character of elements generally increases as you move down a group in the periodic table and decreases as you move across a period from left to right.

So, the order of increasing metallic character for Rb, Cs, K, and Na would be:

Na < K < Rb < Cs

Explanation:

Na (sodium) is the least metallic of the four elements because it is located at the beginning of period 3, which means it has the smallest atomic radius and the highest effective nuclear charge.
K (potassium) is more metallic than Na because it is located below Na in group 1, which means it has a larger atomic radius and a lower effective nuclear charge.
Rb (rubidium) is more metallic than K because it is located below K in group 1, which means it has an even larger atomic radius and an even lower effective nuclear charge.
Cs (cesium) is the most metallic of the four elements because it is located at the bottom of group 1, which means it has the largest atomic radius and the lowest effective nuclear charge

A student is provided an unknown hydrocarbon and perform a combustion experiment. Visually the result of the combustion experiment is a yellow flame that is not very intense and produced a small amount of smoke. Using techniques not discussed in the lab the student found that the combustion reaction produced 6 moles of carbon dioxide and 6 moles of water and that it is less than 5 carbons. Identify the name of the hydrocarbon used in this experiment and calculate the volume (mL) of the hydrocarbon starting material

Answers

The volume of the butane starting material is 24500 mL, or 24.5 liters.

We use the balanced chemical equation for the combustion of a hydrocarbon to determine the number of moles of the hydrocarbon that were used in the experiment:

Hydrocarbon + O₂ → CO₂ + H₂O

We know that 6 moles of CO₂ and 6 moles of H₂O were produced. This means that the hydrocarbon contained 6 carbon atoms  (since each mole of CO₂ produced in the reaction comes from one carbon atom in the hydrocarbon).

Since we also know that the hydrocarbon has less than 5 carbons, this means that it must be either propane (C₃H₈) or butane (C₄H₁₀).

To determine which of these two hydrocarbons was used, we can calculate the theoretical yield of CO₂ for each one and compare it to the actual yield of 6 moles.

For propane, the theoretical yield of CO₂ would be 3 moles, while for butane, it would be 4 moles. Since the actual yield was 6 moles, it is more likely that butane was the hydrocarbon used.

To calculate the volume of the butane starting material, we need to use the ideal gas law:

PV = nRT

Rearranging the equation, we get:

V = nRT/P = (1 mol)(0.0821 L·atm/mol·K)(298 K)/(1 atm) = 24.5 L

Since the volume is in milliliters (mL), we can convert:

24.5 L x 1000 mL/L = 24500 mL

Therefore, the volume of the butane starting material is 24500 mL, or 24.5 liters.

The relative humidity on a summer day is 80 percent. The temperature is 35 °C. Will the dew point be reached if the temperature drops to 25 C later in the evening? Use the table below to find the amount of water vapor needed for saturation at each temperature. Show your work.

Answers

To determine if the dew point will be reached when the temperature drops, we need to calculate the dew point temperature at the current relative humidity and temperature.

Using the table, we can find that the amount of water vapor needed for saturation at 35°C is 42.1 g/m3. To calculate the dew point temperature, we can use the following formula:

dew point temperature = (243.12 × ln(RH/100) + 17.62 × T / (243.12 + T)) / (17.62 - ln(RH/100) - 243.12 × T / (243.12 + T))

where RH is the relative humidity (80 percent) and T is the temperature in degrees Celsius (35°C).

Plugging in the values, we get:

dew point temperature = (243.12 × ln(80/100) + 17.62 × 35 / (243.12 + 35)) / (17.62 - ln(80/100) - 243.12 × 35 / (243.12 + 35))

dew point temperature = 29.9°C

This means that the air would have to cool to 29.9°C in order for the dew point to be reached and condensation to occur. Since the temperature is only dropping to 25°C later in the evening, the dew point will not be reached and condensation will not occur.

this reaction has first order kinetics and a rate constant of 0.00151 s-1. if one starts with 3.489 m of p at time zero, what molarity of p will one have after 10.677 minutes?

Answers

The molarity of p after 10.677 minutes is approximately 1.950 M.

What is first-order kinetics ?

First-order kinetics is a type of reaction kinetics where the rate of the reaction depends on the concentration of only one reactant, raised to the power of one.

If the reaction has first-order kinetics, the rate of the reaction can be described by the following equation:

rate = k[A]

Where

k is the rate constant [A] is the concentration of reactant A

The integrated rate law for a first-order reaction is:

ln([A]t/[A]0) = -kt

Where

[A]t is the concentration of A at time t [A]0 is the initial concentration of A k is the rate constant, and t is the time elapsed

To find the concentration of p after 10.677 minutes, we can plug in the values we have:

ln([A]t/[A]0) = -kt

ln([p]t/3.489 M) = -(0.00151 s^-1)(10.677 min)(60 s/min)

ln([p]t/3.489 M) = -1.026

Taking the exponential of both sides gives:

[p]t/3.489 M = e^-1.026

[p]t = (e^-1.026)(3.489 M) = 1.950 M

Therefore, the molarity of p after 10.677 minutes is approximately 1.950 M.

Answers

A satellite terminates one revolution of a planet in one hour. At the end of one hour, the satellite has moved 2.0 x 10⁷ meters and is only 10 meters away from its starting point. After one hour, the average velocity of the satellite is 2.7 × 10 ⁻² m/s.

What is an average velocity?

Alteration in position divided by the time of travel defines the average velocity.

Given:

Distance = 2.0 x 10⁷ meters

Time = 1 hour

Average speed is calculated as:

Average speed = distance covered by the object ÷ Time to cover the distance

= 2.0 x 10⁷ ÷ 1

= 2.0 x 10⁷ meters ÷ hour

= 5,555 and 5/9 meters/second.

Now,

The term velocity is defined as the ratio of displacement to the time for the displacement.

Velocity = Displacement / Time

= 10 meters/hour

= 0.002777 meters/second

= 2.7 × 10 ⁻² m/s

Nonpolar molecules are generally the least soluble in water. Option B is correct.

Water is a polar molecule, meaning that it has a partial positive charge on one end and a partial negative charge on the other end. This polarity allows water to interact with other polar molecules, such as other water molecules or polar solutes, through hydrogen bonding.

Nonpolar molecules, on the other hand, do not have regions of partial positive and negative charges and are not able to form hydrogen bonds with water molecules. As a result, they are generally not soluble in water. Examples of nonpolar molecules include hydrocarbons, such as oil or grease.

The Part II spectra for Base/Phenolphthalein shows two distinct absorption peaks at 420 nm and 540 nm. These peaks are consistent with the form of the absorption spectrum obtained in Part I of the experiment.

In Part I, we added HCl to the basic solution of phenolphthalein, causing the solution to change from pink to colorless. The color change occurred due to the dissociation of the phenolphthalein molecule into its ionized forms. The ionized forms of phenolphthalein have different absorption spectra than the neutral form. The neutral form absorbs light at a different wavelength than the ionized forms, resulting in a change in the color of the solution. The absorption peaks observed in Part II correspond to the ionized forms of phenolphthalein. The peak at 420 nm is due to the absorption of the hydrogen-bonded form of the ionized molecule, while the peak at 540 nm is due to the non-hydrogen-bonded form.

[25 marks]

Answers

The equation for net potential energy between two adjacent ions, En, is given by:

En = A/r^n + B/r^n

To calculate the bonding energy E0 in terms of the parameters A, B, and n, we can follow the following procedure:

1)Since the curve of En vs r has a minimum at E0, differentiate En with respect to r, and then put the resultant expression equal to zero. This results in:

dEn/dr = -An/r^(n+1) - Bn/r^(n+1) = 0

2) In order to determine no, the equilibrium interionic spacing, one must solve for r in terms of A, B, and n. This results in:

r0 = (An/Bn)^1/n

3) Determine the expression for E0 by substitution of ro into Equation. This gives us:

E0 = A/r0^n + B/r0^n

= A(Bn/An)^n/n + B(An/Bn)^n/n

= (An^n + Bn^n)/n

a) In order to superimpose the three energies on a single plot versus the distance r up to 1.0 nm, we must first calculate each of the energies at each given distance. The attractive energy EA is given by the equation EA = -5.86 x 10-6 p9 ED. The repulsive energy Er is given by Er = 1.436 EA. The net energy En is the sum of the two energies, En = EA + Er.

We can then plot the three energies on a single graph, with the distance r on the x-axis and the energies on the y-axis.

b) From the graph, we can determine the equilibrium spacing r0 and the magnitude of the bonding energy E, between the two ions. The equilibrium spacing r0 is the distance at which the net energy En is at a minimum, which is approximately 0.45 nm. The magnitude of the bonding energy E, is the difference between the net energy at the equilibrium spacing r0 and the repulsive energy at that distance. In this case, the magnitude of the bonding energy E, is approximately 0.2 eV/K+-Cl pair.

c) We can also mathematically determine the r0 and E, values using the solutions to Problem 2. For the equilibrium spacing r0, we can solve the equation En(r) = 0 for r, which yields r0 = 0.45 nm. For the magnitude of the bonding energy E, we can subtract the repulsive energy Er at the equilibrium spacing r0 from the net energy En at that distance, which yields E, = 0.2 eV/K+-Cl pair. This result matches the value we obtained graphically in part b.

isotopes are different forms of an element that have different blank . multiple select question. atomic weights atomic numbers numbers of neutrons numbers of protons

Answers

Same number of protons but different numbers of neutrons is the correct answer.

What are isotopes ?

Isotopes are variants of a chemical element that have the same number of protons in their atomic nucleus but differ in the number of neutrons. Isotopes of the same element have the same atomic number, but different atomic masses. For example, carbon-12, carbon-13, and carbon-14 are three isotopes of the element carbon.Isotopes can have different physical and chemical properties due to differences in their atomic mass. For example, isotopes of an element can have different boiling points, melting points, and densities. This can be important in a wide range of fields, including chemistry, geology, and physics.Some isotopes are unstable and undergo radioactive decay, which can result in the emission of alpha particles, beta particles, or gamma rays. This property of certain isotopes has important applications in nuclear medicine, nuclear power generation, and radiocarbon dating.

The atomic number 46 and the letter Pd serve as the symbol for the chemical element palladium.

What is Palladium?

This rare and brilliant silvery-white metal was first discovered in 1803 by the English chemist William Hyde Wollaston. In homage to the asteroid Pallas, which was given that name by the Greek goddess Athena after killing Pallas he gave it the name Pallas. The elements palladium, platinum, rhodium, ruthenium, iridium, and osmium are all included in the platinum group metals, which represent a group of different materials (PGMs). Palladium is the least dense and has the lowest melting point of the group despite having similar chemical properties.

The majority of palladium is used in catalytic converters for automobiles. It is also used in many jewelry pieces as well as dental crowns and fillings. Gold that has undergone decolorization through alloying with another metal, occasionally palladium, is known as white gold.

Draw the structure of the major organic product of the reaction below.CH3​CH2​OCH2​CH2​CH=CH2​+CH2​I2​ Zn(Cu)/ether. ​−- Use the wedge/hash bond tools to indicate stereochemistry where it exists. - Show stereochemistry in a meso compound. - If the reaction produces a racemic mixture, just draw one stereoisomer.

Answers

The major organic product of the reaction is a disubstituted dihalomethane, with a structure of [tex]CH3-CH(CH3)-CH-I-CH3[/tex]. This compound is optically inactive, and thus a meso compound.

The reaction of [tex]CH3-CH(CH3)-CH=CH2[/tex] with [tex]CH2I2[/tex] upon reacting with Zn(Cu) produces a meso compound, meaning that the molecule contains two or more identical groups attached to opposite sides of a stereocenter. Stereochemistry is not applicable here, so the structure does not need to be drawn with wedge/hash bonds. The reaction produces a racemic mixture, which means that the product is an equal mixture of two stereoisomers that are mirror images of each other. As such, since only one stereoisomer needs to be drawn, the structure of [tex]CH3-CH(CH3)-CH-I-CH3[/tex] is sufficient to represent the major organic product.

At a certain temperature, the equilibrium constant, Kc, for this reaction is 53.3.
H2 (g) + I2 (g) <----> 2HI (g) Kc=53.3
At this temperature, 0.500 mol of H2 and 0.500 mol of I2 were placed in a 1.00-L container to react. What concentration of HI is present at equilibrium?
HI = ....M

Answers

The concentration of HI present at equilibrium is 0.516 M when 0.500 mol of H2 and 0.500 mol of I2 were placed in a 1.00-L container to react.

The balanced chemical equation for the reaction is:

H2 (g) + I2 (g) ⇌ 2HI (g)

The initial molar concentrations are:

[H2] = 0.500 mol/1.00 L = 0.500 M

[I2] = 0.500 mol/1.00 L = 0.500 M

[HI] = 0 M (since there is no HI initially)

Let x be the change in concentration of H2, I2 and HI at equilibrium. Since 2 mol of HI is formed for every 1 mol of H2 or I2 reacted, the equilibrium concentrations can be expressed as:

[H2] = 0.500 - x

[I2] = 0.500 - x

[HI] = 2x

Substitute these expressions into the equilibrium constant expression:

[tex]Kc = [HI]^2 / ([H2] *[I2])[/tex]

[tex]53.3 = (2x)^2 / ((0.500 - x) * (0.500 - x))[/tex]

Solving for x using quadratic formula gives x = 0.258 M.

Therefore, the concentration of HI at equilibrium is:

[HI] = 2x = 2(0.258) = 0.516 M.

So the concentration of HI present at equilibrium is 0.516 M.
