Answers

Dialcohol and diacid are bifunctional molecules that can be used in the synthesis of polyesters. In a polyester, the dialcohol and diacid react to form an ester bond, resulting in a long chain polymer.

Diesters can also be used in the synthesis of polyesters, as they can be hydrolyzed to form two carboxylic acid groups and two alcohol groups, which can then react to form an ester bond. Therefore, diesters are also a material used in the synthesis of polyesters.

Diamines and diacids can react to form nylon, so they are bifunctional molecules used in the synthesis of nylons. The reaction between a diamine and diacid forms an amide bond, which leads to a long-chain polymer.

Dinitro and diether are bifunctional molecules that are neither used in the synthesis of polyesters nor nylons. Dinitro compounds typically have nitro groups attached to each of the functional groups, making them more reactive and often used as explosives.

Diethers, on the other hand, can be used in organic synthesis as protecting groups for alcohols or carbonyl groups, but they do not have a direct role in the synthesis of polyesters or nylons.

If you have 16 moles of o2 in a balloon what is the volume of oxygen in the balloon

Answers

If you have 16 moles of O2 in a balloon at 25°C and 1 atm, the volume of oxygen in the balloon is 390.5 liters.

The volume of oxygen in a balloon containing 16 moles of O2 depends on the temperature and pressure of the gas. To find the volume, we can use the ideal gas law equation PV = nRT, where P is the pressure of the gas, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

Assuming the temperature and pressure are constant, we can rearrange the equation to solve for volume: V = nRT/P. The value of R is 0.0821 L·atm/mol·K.

Let's assume that the temperature is 25°C, or 298 K, and the pressure is 1 atm. Plugging in the values, we get:

V = (16 mol)(0.0821 L·atm/mol·K)(298 K)/(1 atm)

V = 390.5 L

Therefore, if you have 16 moles of O2 in a balloon at 25°C and 1 atm, the volume of oxygen in the balloon is 390.5 liters.

of HI. Calculate the equilibrium constant, K, for
the reaction H2(g) + I2(g) ⇄ 2HI(g).

Answers

The equilibrium constant, K, for the reaction H2(g) + I2(g) ⇄ 2HI(g) can be calculated using the expression K= [HI]2/([H2][I2]). Since the concentrations of H2, I2, and HI are given in the question, we can calculate the equilibrium constant, K, for the reaction.

K = [HI]2/([H2][I2]) = (1.77 × 10-2)2/((1.83 × 10-3)(3.13 × 10-3)) = 4.43 × 104. Therefore, the equilibrium constant, K, for the reaction H2(g) + I2(g) ⇄ 2HI(g) at 425°C is 4.43 × 104.

Using the specified concentrations of H2, I2, and HI, it appears that you have correctly calculated the equilibrium constant, K, for the reaction H2(g) + I2(g) 2HI(g) at 425°C. The ratio of the concentrations of the reactants and products at equilibrium, K, is represented by each concentration being raised to the power of its stoichiometric coefficient.

The concentration of the product, HI, is preferred above the concentrations of the reactants, H2 and I2, at equilibrium, as shown by the value of K = 4.43 104 in this instance. This suggests that at equilibrium, the forward reaction—the creation of HI—is preferred.

It is significant to remember that the equilibrium constant, K, is temperature-dependent, and that temperature changes affect K's value.

Answers

The addition of HBr to 2-methyl-2-butene is an example of an electrophilic addition reaction. The correct answer is (2)

The double bond in 2-methyl-2-butene is attacked by the electrophilic H+ ion from HBr, leading to the formation of a carbocation intermediate. The bromide ion (Br-) then attacks the carbocation, leading to the formation of a new carbon-bromine bond. The major organic product obtained from the addition reaction of HBr to 2-methyl-2-butene is 2-bromo-2-methylbutane, which is also known as t-butyl bromide. This is because the addition of HBr occurs at the tertiary carbon, leading to the formation of a tertiary carbocation intermediate, which is relatively stable.

You're given an unknown acid and told that it will donate one proton per molecule. When 1. 0 g of this acid is dissolved in water, the resulting solution requires 50. 0 ml of a 0. 25 M solution of NaOH for neutralization. What's the molecular mass of the unknown acid? Explain. (Hint: Find the moles of acid present)

Answers

The molecular mass of the unknown acid is 100 g/mol.

To find the molecular mass, first determine the moles of acid present. Since 50.0 mL of 0.25 M NaOH is required for neutralization, calculate the moles of NaOH using the formula: moles = Molarity × Volume (in L).

Moles of NaOH = 0.25 mol/L × (50.0 mL × 0.001 L/mL) = 0.0125 mol

Since the acid donates one proton per molecule, the moles of acid present equal the moles of NaOH: 0.0125 mol.

Next, find the mass of one mole of the unknown acid. You have 1.0 g of the acid, so divide the mass by the moles to get the molecular mass:

Molecular mass = Mass / Moles = 1.0 g / 0.0125 mol = 100 g/mol

Naturally occurring potassium consists of potassium-39 and potassium-41. calculate the percentage of each isotope present if theaverage is 39.1.

Answers

When the average is 39.1, naturally occurring potassium consists of 50% potassium-39 and 50% potassium-41.

An isotope is a variant of an element that has the same number of protons but a different number of neutrons in its nucleus. Potassium has two naturally occurring isotopes: potassium-39 and potassium-41. To calculate the percentage of each isotope present when the average is 39.1, we can use the following formula:

% of potassium-39 = (39.1 - 41) / (39 - 41) x 100%
% of potassium-41 = 100% - % of potassium-39

Using this formula, we can first calculate the percentage of potassium-39:

% of potassium-39 = (39.1 - 41) / (39 - 41) x 100%
% of potassium-39 = -1 / (-2) x 100%
% of potassium-39 = 50%

This means that potassium-39 makes up 50% of the naturally occurring potassium. To calculate the percentage of potassium-41, we simply subtract the percentage of potassium-39 from 100%:

% of potassium-41 = 100% - 50%
% of potassium-41 = 50%

Therefore, potassium-41 also makes up 50% of the naturally occurring potassium. In summary, when the average is 39.1, naturally occurring potassium consists of 50% potassium-39 and 50% potassium-41.

26. Over time an open soft drink will lose carbonation (dissolved CO2


Which of these allows the CO2 to remain in solution the longest?


O Reduced air pressure


Exposure to direct sunlight


Increased air currents


O Cooler temperatures

Answers

Out of the options provided, cooler temperatures allow CO2 to remain in solution the longest.

When a soft drink is opened, CO2 molecules start to escape from the solution and accumulate in the headspace of the container. Higher temperatures increase the kinetic energy of the CO2 molecules, causing them to move faster and escape the solution more quickly. In contrast, cooler temperatures reduce the kinetic energy of the CO2 molecules, slowing down their movement and allowing them to remain in solution for a longer period of time.

Reduced air pressure, exposure to direct sunlight, and increased air currents can all further accelerate the loss of carbonation in an open soft drink. Reduced air pressure lowers the atmospheric pressure, which decreases the solubility of CO2 in the liquid. Exposure to direct sunlight increases the temperature of the drink and causes the CO2 molecules to escape more quickly. Increased air currents can also cause CO2 to escape more quickly by creating turbulence in the liquid.

Therefore, to keep a soft drink fizzy for longer, it is best to store it in a cool place and avoid exposing it to direct sunlight, reducing air pressure or increased air currents.

The pressure of the gas can be calculated using the ideal gas law formula:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

First, we need to calculate the number of moles of sulfur:

molar mass of sulfur = 32 g/mol

number of moles = mass/molar mass

= 20 mol

Next, we need to convert the volume from milliliters to liters and the temperature from Celsius to Kelvin:

V = 540 ml = 0.54 L

T = 47°C + 273.15 = 320.15 K

Finally, we can plug in the values and solve for pressure
