which molecule dissociates completely in water, meaning that each molecule in a sample releases a h ion? (write the formula of the molecule.)

When 1 mole of Br2 reacts with 3-methylenecyclopentene, a 1,4-addition reaction occurs. This means that the bromine atoms will add to the carbon atoms in the 1 and 4 positions of the cyclopentene ring. The product formed will be a trans-1,4-dibromocyclohexene.

The mechanism of this reaction involves the formation of a bridged bromonium ion intermediate, but we are assuming that it does not prevent 1,4-addition from happening. Therefore, the products will be:

1. Trans-1,4-dibromocyclohexene, where the bromine atoms are added to the 1 and 4 positions of the cyclopentene ring.

2. Trace amounts of cis-1,4-dibromocyclohexene, where the bromine atoms are added to the 1 and 4 positions of the cyclopentene ring, but with a cis stereochemistry. This is a minor product because the trans isomer is more stable due to the trans-annular strain in the cis isomer.

The structures of these products can be drawn as follows:

Trans-1,4-dibromocyclohexene:
CH2
| Br
C   Br
|
C---C
|
C   Br
|
CH2

Cis-1,4-dibromocyclohexene:
CH2
| Br
C   Br
|
C---C
|
Br  CH2

The reaction proceeds as follows:

1. When 3-methylenecyclopentene reacts with 1 mole of Br2, a bridged bromonium ion intermediate is formed.
2. Since the bridged bromonium ion intermediate does not prevent 1,4-addition from happening, the Br- ion will attack the adjacent carbon atom, leading to 1,4-addition.
3. As a result, two products will be formed: a 1,2-addition product (1-bromo-2-(bromomethyl)cyclopentane) and a 1,4-addition product (1,5-dibromocyclopentane).

To summarize, the structures of the products formed by the reaction of 1 mole of Br2 with 3-methylenecyclopentene are 1-bromo-2-(bromomethyl)cyclopentane and 1,5-dibromocyclopentane, with the formation of a bridged bromonium ion intermediate and 1,4-addition occurring.

N-Chloromethylamine is the name given to the molecule. The provided molecule contains the highly electronegative components nitrogen and chlorine, as can be seen. Hydrogen bonding is not visible because of the enormous size of chlorine, whereas it is visible because of the lower size of nitrogen.

Because it is too big, the chlorine atom in chloromethane cannot form hydrogen bonds. In chloromethane, the hydrogen atoms are not sufficiently electropositive and are not linked to an electronegative atom. As a result, chloromethane and water molecules are unable to establish hydrogen bonds.

Answer:

Insoluble substances remain the same when in water.

Explanation:

When a substance is regarded as insoluble, it means that the substance remains the same in water.

Soluble substances usually form one continuous phase with water when they are added to water (eg when salt is added to water).

However, when camphor is added to water, it does not form a single phase with water. It remains the same in the water and maintains a separate phase from the water. Hence camphor is an insoluble substance.

The Hall coefficient (RH) in this case is approximately -3.01 * 10^-6 C^-1 cc (rounded to three significant figures in exponential notation).

The Hall coefficient (RH) is a parameter used to describe the behavior of charge carriers in a material when subjected to a magnetic field. It is given by the equation RH = 1/(e * p) where e is the elementary charge and p is the total charge carrier density. In this case, we are given the acceptor doping concentration (Na) and the donor doping concentration (Nd) in units of /cc.

To calculate the Hall coefficient, we need to determine the total charge carrier density (p). The total charge carrier density can be calculated as the difference between the acceptor doping concentration and the donor doping concentration: p = Na - Nd.

Given the acceptor doping concentration Na = 4.18 * 10^15/cc and the donor doping concentration Nd = 9.40 * 10^15/cc, we can substitute these values into the equation to find p:

p = Na - Nd
  = (4.18 * 10^15/cc) - (9.40 * 10^15/cc)
  = -5.22 * 10^15/cc

Now, we can substitute the value of p into the Hall coefficient equation:

RH = 1/(e * p)
    = 1/(1.60 * 10^-19 C * (-5.22 * 10^15/cc))
    = -3.01 * 10^-6 C^-1 cc

Answer:

The system will shift to the left producing more moles of gases trying to maintain the original pressure of the system

Explanation:

Based on LeChatelier's principle, a change in temperature, pressure, volume or concentration on a system result in an opposing change trying to maintain the initial equilibrium conditions.

In the reaction:

N₂(g) + 3H₂(g) ⇄ 2NH₃(g)

4 moles of gas reacts producing 2 moles of gas.

In a gas reaction, the system will try to maintain the total pressure.

If the volume of the container increases, the system will shift to the side of the reaction that has more moles of gases in order to maintain the pressure.

That means if in the reaction the volume of the container increase from 2.0L to 4.0L the system will shift to the left producing more moles of gases trying to maintain the original pressure of the system.

We were only asked to calculate the moles of zinc, the answer is simply:

moles Zn = 0.0304 mol

The given experimental data can be used to calculate the number of moles of hydrogen gas produced in the reaction with zinc.

To do so, we need to use the ideal gas law: PV = nRT, where P is the pressure of the gas, V is the volume of the container, n is the number of moles of the gas, R is the gas constant, and T is the temperature.

First, we need to calculate the volume of the container using the data for zinc metal. From the given data, we know that the mass of zinc used in the reaction is 1.9887 g. Using the molar mass of zinc (65.38 g/mol), we can calculate the number of moles of zinc:

moles Zn = 1.9887 g / 65.38 g/mol = 0.0304 mol

Next, we can use the pressure of hydrogen gas and the mass of the unknown sample to calculate the number of moles of hydrogen produced. We can assume that the volume of the container is the same for both unknown samples:

n = PV/RT = (P x V)/(R x T)

For unknown sample 1, we have:

n = (3372.7 torr x V)/(62.3637 L•torr/mol•K x 298 K)

For unknown sample 2, we have:

n = (2014.7 torr x V)/(62.3637 L•torr/mol•K x 298 K)

We can solve for V by setting the two expressions equal to each other:

(3372.7 torr x V)/(62.3637 L•torr/mol•K x 298 K) = (2014.7 torr x V)/(62.3637 L•torr/mol•K x 298 K)

Solving for V, we get V = 1.995 L

Finally, we can use the moles of hydrogen and the mass of the unknown sample to calculate the molar mass of the unknown compound. However, since we were only asked to calculate the moles of zinc, the answer is simply:

The physical properties of aldehydes and ketones are governed by the presence of a carbonyl functional group. This functional group contains a carbon atom double-bonded to an oxygen atom, which imparts unique chemical and physical properties to aldehydes and ketones.

The polarity of the carbonyl group makes aldehydes and ketones highly reactive with nucleophiles, and it also affects their boiling points and solubility. The dipole-dipole interaction between the carbonyl group and neighboring molecules affects the boiling point of aldehydes and ketones, which increases as the size of the molecule increases. In general, aldehydes have lower boiling points than ketones because they have one fewer carbon atom, making them less polar and less likely to form strong intermolecular forces. Additionally, the presence of the carbonyl group increases the acidity of aldehydes and ketones, making them weak acids. Overall, the unique physical properties of aldehydes and ketones can be attributed to the presence of the carbonyl functional group.

(i) The initial-boundary value problem for the given scenarios are as follows:

a) Scenario a:

PDE: ∂u/∂t = k * ∂²u/∂x²

Initial condition: u(x, 0) = 100 (boiling water temperature)

Boundary conditions: u(0, t) = 10, u(L, t) = 10 (constant temperature at the ends)

b) Scenario b:

PDE: ∂u/∂t = k * ∂²u/∂x²

Initial condition: u(x, 0) = 100 (boiling water temperature)

Boundary conditions: u(0, t) = 0 (temperature at x=0), ∂u/∂x(L, t) = 0 (thermal insulation at x=L)

(iii) The solution for the temperature distribution as time approaches infinity can be found by solving the appropriate steady state equation.

(i) The initial-boundary value problem formulation states the partial differential equation (PDE) governing the temperature distribution in the aluminum bar, along with the initial condition and boundary conditions.

In scenario (a), both ends of the bar are immersed in a medium with a constant temperature of 10 degrees Celsius, while in scenario (b), the end at x=0 is immersed in a medium with temperature 0 degrees Celsius and the end at x=L is insulated.

(ii) As time approaches infinity, the temperature distribution in the bar tends to reach a steady state.

In scenario (a), the temperature throughout the bar will eventually approach a constant value of 10 degrees Celsius, since both ends are immersed in a medium with that temperature.

In scenario (b), the temperature at x=0 will approach 0 degrees Celsius, while the temperature at x=L will remain constant due to thermal insulation.

(iii) To find the solution as time approaches infinity, we need to solve the appropriate steady state equation.

In scenario (a), the steady state equation is ∂²u/∂x² = 0, which implies that the temperature gradient is zero throughout the bar, resulting in a constant temperature of 10 degrees Celsius.

In scenario (b), the steady state equation is ∂²u/∂x² = 0 with the boundary condition u(0) = 0, which implies a linear temperature distribution from 0 degrees Celsius at x=0 to a constant temperature at x=L due to insulation.

1.63atm is the required pressure of the given gas.

To calculate the pressure of gas using the ideal gas law, we need to use the formula:

PV = nRT

where:

First, we need to calculate the number of moles of CO2 using the given mass and molar mass:

n = m/M

where:

m = mass of CO2 = 2.89 g

M = molar mass of CO2 = 44.01 g/mol

n = 2.89 g / 44.01 g/mol = 0.0657 mol

Next, we can plug in the values into the ideal gas law and solve for pressure (P):

PV = nRT

P = nRT / V

P = (0.0657 mol) (0.08206 L·atm/mol·K) (255.22 K) / 9.60 L
