The first component is a six-carbon linear structure. Then we'll need to add a methyl group to a five-carbon linear structure.

Constitutional isomers:

This methyl group can be linked to either carbon 2 or carbon 3 in the carbon chain. Finally, we can make a four-carbon linear structure by adding two methyl groups. This addition can be done with carbon 2 alone or with carbon 2 and carbon 3 together.

The constitutional isomers have the same chemical formula, but their atom connections are different. Chain isomers, position isomers, and functional group isomers are the three forms of constitutional isomers.

In this experiment, a piece of metal at 100 °C is placed in 25 °C water inside a perfectly insulated calorimeter. The temperature change of the water is measured until it reaches a constant temperature.

Assuming that all the heat from the metal is transferred to the water, we can use the principle of energy conservation to calculate the specific heat capacity of the metal. The energy gained by the water can be calculated using the formula Q = mcΔT, where Q is the energy gained, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the change in temperature.

Since the calorimeter is perfectly insulated, the energy gained by the water is equal to the energy lost by the metal. Therefore, the specific heat capacity of the metal can be calculated using the formula Q = mcΔT, where m is the mass of the metal and c is the specific heat capacity of the metal.
To calculate the specific heat capacity of the metal, you need to know the mass of the water, the specific heat capacity of water, the change in temperature of the water, and the mass of the metal. Once you have these values, you can use the formula to calculate the specific heat capacity of the metal.

When 1.540 g of oxalic acid was burned in oxygen, 1.504 g of CO2 and 0.310 g of water were formed.

The empirical formula for oxalic acid can be determined by calculating the mass percent of each element in the compound.

To calculate the empirical formula for oxalic acid:

Mass percent of carbon = (mass of carbon/molar mass of compound) × 100

Mass percent of carbon = (1.504 g carbon dioxide × 12.01 g/mole carbon)/ (44.01 g/mole CO2) × 100

Mass percent of carbon = 48.2%

Mass percent of hydrogen = (mass of hydrogen/molar mass of compound) × 100

Mass percent of hydrogen = (0.310 g water × 2.02 g/mole hydrogen)/ (18.02 g/mole H2O) × 100

Mass percent of hydrogen = 6.87%

Mass percent of oxygen = 100% - (mass percent of carbon + mass percent of hydrogen)

Mass percent of oxygen = 100% - (48.2% + 6.87%)

Mass percent of oxygen = 44.93%

Therefore, the empirical formula of oxalic acid is: C2H204

If the molecular mass of oxalic acid is 90.0, the molecular formula can be determined by dividing the molecular mass by the empirical formula mass. The molecular mass is 90.0 g/mol.

The empirical formula mass can be calculated as follows:

Empirical formula mass = (2 × atomic mass of carbon) + (2 × atomic mass of hydrogen) + (4 × atomic mass of oxygen)

Empirical formula mass = (2 × 12.01 g/mol) + (2 × 1.01 g/mol) + (4 × 16.00 g/mol)

Empirical formula mass = 90.04 g/mol

Therefore, the molecular formula of oxalic acid is the same as the empirical formula: $$\text{C}_{2}\text{H}_{2}\text{O}_{4}$$

The question presents a table with many multiplications using different units (mass and velocity) and requires us to decide whether the operations presented are possible.

To solve this question, we should keep in mind this general rule: for units reffering to the same measurement (for example: mass, volume, distance etc.), we are able to multiply the units as long as they are the same. For example: g x g, L x L, m x m. If units are about the same measurement but still different, we should convert one of them in order to make them the same.

On the other hand, when we are talking about division, if we have the same unit on the operator and denominator position, we will have a result as "1" - then we need to analyze the entire value.

Now, considering the operations presented in the question:

On the first one, we have kg multiplied by kg. Although it isn't usual to see square kg (kg^2), we are able to make this operation:

On the second line, we have square g multiplied by kg. In this case, since the first unit is square, we can assume they are not about the same measurement. Thus, we can't complete this operation.

On the third line, there is a division and we should proceed as a normal operation (although the unit km/s isn't usual):

In summary, the answers should be:

1) Is it possible? YES / Result = 45 kg^2

2) Is it possible? NO

3) Is it possible? YES / Result = 0.8 km/s

Because the conducting zone structures have no gas exchange function, they are called anatomical dead space. The respiratory system can be divided into two main zones: the conducting zone and the respiratory zone.

The conducting zone refers to the series of airways that transport air into and out of the lungs. It includes structures such as the nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles.

The purpose of the conducting zone is to facilitate the movement of air, providing a pathway for the inhaled and exhaled air to travel through. However, this zone does not participate in the actual exchange of gases, such as oxygen and carbon dioxide, between the respiratory system and the bloodstream.

Due to the absence of gas exchange in the conducting zone structures, it is referred to as anatomical dead space. The term "dead space" indicates that these regions do not contribute to the exchange of gases and are solely involved in the transportation of air.

Answer:

Relative volume of ether to water that should be used for the extraction = 1.205

Explanation:

The extraction/distribution coefficient of an arbitrary solvent to water for a given substance is expressed as the mass concentration of the substance in the arbitrary solvent (C₁) divided by the mass concentration of the substance in water (C₂).

K = (C₁/C₂)

Let the initial mass of the organic substance X in water be 1 g (it could be any mass basically, it is just to select a right basis, since we are basically working with percentages here).

If 94% of the organic substance X is extracted by ether in a single extraction, 0.94 g ends up in ether and 0.06 g of the organic substance X that remains in water.

Let the volume of ether required be x mL.

Let the volume of water required be y mL.

Relative volume of ether to water that should be used for the extraction = (x/y)

Mass concentration of the organic substance X in ether = (0.94/x)

Mass concentration of organic substance X in water = (0.06/y)

The distribution coefficient , Ko (Cether / C water), for an organic substance X at room temperature is 13.

13 = (0.94/x) ÷ (0.06/y)

13 = (0.94/x) × (y/0.06)

13 = (15.667y/x)

(x/y) = (15.667/13) = 1.205

Okay, let's solve this step-by-step without using quadratics:

1) The equilibrium constant Kc = 0.36 means the equilibrium lies to the left. So there will be more N2O4 than NO2 at equilibrium.

2) The initial concentration of N2O4 is 0.1 mol dm^-3. Let's call this [N2O4]initial.

3) At equilibrium, the concentrations of N2O4 and NO2 will be [N2O4]equil and [NO2]equil respectively.

4) We know the equilibrium constant expression for this reaction is:

Kc = ([NO2]equil)^2 / [N2O4]equil

5) Setting this equal to 0.36 and plugging in 0.1 for [N2O4]initial, we get:

0.36 = ([NO2]equil)^2 / (0.1 - [NO2]equil)

6) Simplifying, we get:

0.036 = [NO2]equil^2

7) Taking the square root of both sides, we get:

[NO2]equil = 0.06 mol dm^-3

So the equilibrium concentration of NO2 is 0.06 mol dm^-3.
