D. The mass of the sample and the masses of the elements found in the sample.

The molecular formula of dichloroacetic acid is C₁₂H₁₀Cl₂O₄.

Given,

Empirical formula = CHOCl

Molecular mass = 129 amu

The empirical formula (CHOCl) gives the relative ratios of carbon (C), hydrogen (H), and chlorine (Cl) atoms in the compound.

Empirical formula molar mass:

(1 atom of C × atomic mass of C) + (1 atom of H × atomic mass of H) + (1 atom of O × atomic mass of O) + (1 atom of Cl × atomic mass of Cl)

= (1 × 12.01) + (1 × 1.01) + (1 × 16.00) + (1 × 35.45)

= 12.01 + 1.01 + 16.00 + 35.45

= 64.47 g/mol

The ratio of the molecular mass to the empirical formula mass:

Ratio = Molecular mass / Empirical formula mass

= 129 amu / 64.47 g/mol

To convert grams to amu, it is required to use Avogadro's number (6.022 x 10²³).

Ratio = 129/64.47 x 6.022 x 10²³

= 1.208 x 10²³ atoms

This means that the molecular formula of dichloroacetic acid is a multiple of the empirical formula by a factor of approximately 1.208 x 10²³.

Therefore, the molecular formula of dichloroacetic acid is C₁₂H₁₀Cl₂O₄.

The percent composition of carbon dioxide is as follows: 27.3% carbon, 72.7% oxygen.

To calculate the percent composition of the compound, we can assume that we have one mol of carbon dioxide. The molar mass of carbon dioxide is 44 g/mol.

Based on the molecular formula of carbon dioxide (CO₂), we can say that 1 mol of CO₂ contains 1 mol of carbon and two moles of oxygen.

The molar mass of carbon is 12 g/mol, and we can calculate its percent by mass by dividing the mass of carbon in carbon dioxide by the mass of carbon dioxide and multiplying the result by 100%:

%C = 100% * 12 g/mol / 44 g/mol

%C = 27.3%

Because carbon dioxide is made of only carbon and oxygen, we can the oxygen percent by mass by simply subtracting the carbon percent by mass from 100%:

%O = 100% - %C

%O = 100% - 27.3%

%O = 72.7%

Some types of reactions used to convert straight chain alkanes into branched hydrocarbons and aromatic compounds include dehydrogenation and isomerization reactions.

Dehydrogenation reactions involve the removal of hydrogen atoms from the straight chain alkane to form a double bond, resulting in the formation of a branched hydrocarbon or an aromatic compound. For example, the dehydrogenation of n-butane (C₄H₁₀) can yield isobutene (C₄H₈), which is a branched hydrocarbon.

Isomerization reactions, on the other hand, involve rearranging the carbon atoms within the straight chain alkane to create a different structural isomer. This process leads to the formation of branched hydrocarbons. For instance, the isomerization of n-pentane (C₅H₁₂) can result in the formation of isopentane (C₅H₁₂), which is a branched hydrocarbon.

These reactions are commonly employed in the petrochemical industry to modify the properties of alkanes, such as increasing their octane rating or producing compounds with specific chemical functionalities.

By converting straight chain alkanes into branched hydrocarbons and aromatic compounds, these reactions enable the synthesis of a wide range of valuable products.

Therefore, Dehydrogenation and isomerization reactions are employed to transform linear alkanes into branched hydrocarbons and aromatic compounds. These reactions involve the removal of hydrogen atoms or rearrangement of carbon atoms to create compounds with different structures and properties.

Le Chatelier's principle states that a system at equilibrium will respond to any external stress in such a way as to partially counteract the stress and re-establish equilibrium. In the case of increasing the concentration of H+, which is the same as decreasing pH, the system will respond by shifting the equilibrium towards the product side, which is lactic acid.

Lactic acid is formed from the reaction between pyruvate and lactate dehydrogenase. This reaction is reversible, and the equilibrium can be represented by the equation:
Pyruvate + NADH + H+ <-> Lactic acid + NAD+
In this equation, H+ is a reactant, and increasing its concentration will shift the equilibrium to the right, favouring the formation of more lactic acid. This is because the addition of H+ ions will drive the equilibrium towards the product side, in accordance with Le Chatelier's principle.

Furthermore, since the production of lactic acid from pyruvate is a key step in anaerobic respiration, the increase in H+ concentration will also result in an increase in the production of ATP, which is essential for cellular energy metabolism. Therefore, increasing the concentration of H+ will ultimately lead to an increase in the concentration of lactic acid.
In conclusion, the increase in the concentration of H+ will cause the equilibrium of the reaction to shift towards the formation of more lactic acid, which is a key step in anaerobic respiration and ATP production. This is due to the application of Le Chatelier's principle, which predicts that the system will respond to external stresses in order to re-establish equilibrium.

The answer is (e) 70 milliliters.

Let's assume that x milliliters of the 35% saline solution were used.

The total amount of saline in the solution can be calculated as follows:

Saline in 35% solution = 0.35 * x

Saline in 75% solution = 0.75 * 10 (since 10 milliliters of the 75% solution were used)

The total amount of saline in the resulting 40% solution can be calculated as:

Saline in 40% solution = 0.40 * (x + 10)

Since the saline is being mixed, the total saline in the resulting solution is equal to the sum of the saline in the individual solutions:

0.35 * x + 0.75 * 10 = 0.40 * (x + 10)

Simplifying the equation:

0.35x + 7.5 = 0.40x + 4

Subtracting 0.35x and 4 from both sides:

7.5 - 4 = 0.40x - 0.35x

3.5 = 0.05x

Dividing both sides by 0.05:

x = 3.5 / 0.05

x = 70

Therefore, 70 milliliters of the 35% saline solution were used. The answer is (e) 70 milliliters.

Ignoring electron repulsion, the ground state energy of helium can be related to that of hydrogen by a factor of 4.

This is due to the fact that the ground state energy of an atom is determined by the total energy of its electrons, which is primarily determined by their positions and motions around the nucleus. In the case of hydrogen, the ground state energy is determined by the electron's interaction with the positively charged nucleus. This interaction results in a specific energy level that the electron can occupy.

However, in the case of helium, there are two electrons that occupy the same space and interact with the same nucleus. This results in the phenomenon known as electron repulsion, which makes the energy level of helium higher than that of hydrogen. To ignore electron repulsion means to assume that the two electrons in helium do not interact with each other, which allows us to treat helium as if it had only one electron.

By doing this, the energy level of helium becomes comparable to that of hydrogen, and we can relate them by a factor of 4, which is the ratio of the charge of the helium nucleus to that of the hydrogen nucleus. In summary, ignoring electron repulsion allows us to relate the ground state energy of helium to that of hydrogen by a factor of 4, which is a useful approximation in certain situations.

Chemicals that help keep body fluids within a normal pH range are called buffers.

What are buffers?

A buffer is a chemical solution that can be added to a solution to regulate its acidity. Buffers work by regulating pH in the solution, keeping it within a specific range. A buffer is a solution made up of a weak acid and its conjugate base, or a weak base and its conjugate acid.

A solution with a pH of 7 is considered neutral, while a pH of less than 7 is acidic and a pH of more than 7 is alkaline or basic. It's worth noting that a buffer can only be used to maintain pH in a specific range. When a solution's pH is outside of the buffer's range, it will no longer be able to control pH levels.

Buffers in the body:

Our blood contains a variety of chemicals and hormones that help keep our body's pH levels within a safe range. Buffers play an essential role in this process, ensuring that the body's pH remains within a healthy range of around 7.35 to 7.45. When the pH of our body fluids is too high or too low, it can be detrimental to our health.
