Hello,

In this case, among the options, assuming for all the fuels a mass of 100 g, the combustion reaction reaction and stoichiometry for carbon dioxide is shown below:

A) Benzene C6H6

\(C_6H_6+\frac{15}{2} O_2\rightarrow 6CO_2+3H_2O\)

\(m_{CO_2}=100gC_6H_6*\frac{1molC_6H_6}{78gC_6H_6}*\frac{6molCO_2}{1molC_6H_6} *\frac{44gCO_2}{1molCO_2} =347.4gCO_2\)

B) Cyclohexane C6H12

\(C_6H_{12}+9 O_2\rightarrow 6CO_2+6H_2O\)

\(m_{CO_2}=100gC_6H_{12}*\frac{1molC_6H_{12}}{84gC_6H_{12}}*\frac{6molCO_2}{1molC_6H_{12}} *\frac{44gCO_2}{1molCO_2} =314.3gCO_2\)

C) Glucose C6H12O6

\(C_6H_{12}O_6+6 O_2\rightarrow 6CO_2+6H_2O\)

\(m_{CO_2}=100gC_6H_{12}O_6*\frac{1molC_6H_{12}O_6}{180gC_6H_{12}O_6}*\frac{6molCO_2}{1molC_6H_{12}O_6} *\frac{44gCO_2}{1molCO_2} =146.7gCO_2\)

D) Methane CH4

\(CH_4+2O_2\rightarrow CO_2+2H_2O\)

\(m_{CO_2}=100gCH_4*\frac{1molCH_4}{16gCH_4}*\frac{6molCO_2}{1molC_6H_{12}} *\frac{44gCO_2}{1molCO_2} =1650gCO_2\)

Therefore, for equal masses D) Methane CH4 yield the greatest mass of carbon dioxide.

The compound that contains both carboxyl and amino functional groups in the same molecule is an amino acid. The amino group is NH2 and the carboxyl group is COOH.

The basic structure of an amino acid consists of a central carbon atom known as the alpha carbon. The central carbon atom is attached to an amino group (-NH2), a carboxyl group (-COOH), and an R group that is unique to each amino acid.  The amino acid’s amino group and carboxyl group are bonded together via a peptide bond that is formed via a condensation reaction between the two groups.

The peptide bond, which links amino acids together to form proteins, is a covalent bond between the carboxyl group of one amino acid and the amino group of another amino acid. Hence, it is not wrong to say that an amino acid is the compound that contains both carboxyl and amino functional groups in the same molecule.

Answer

1.50 mol

Explanation

Given:

Initial volume, V₁ = 25.0 L

Mass of CH4 gas in 25.0 L container = 40 g

Final volume, V₂ = 15.0 L

From the Periodic Table; molar mass of CH4 = 16.04 g/mol

What to find:

The new amount in mole.

Step-by-step solution:

According to Avogadro’s law: For a confined gas, the volume (V) and number of moles (n) are directly proportional if the pressure and temperature both remain constant. That is:

n₁ = Mass/Molar mass = (40.0g/16.04 g/mol) = 2.493765586 mol

n₂ is the new amount in mole and can be calculated as follows:

The new amount in moles is 1.50 moles

The given nuclear equation represents the decay of a polonium nucleus to form a lead nucleus, emitting an alpha particle. The value of A is 210, and the value of Z is 84.

Value of A = 210, and the value of Z = 84.

Polonium-210, with a half-life of 138.376 days, undergoes alpha decay to produce lead-206. The energy of the emitted alpha particle is 5.407 MeV.The alpha particle is the least energetic of the three types of radioactive particles, with a charge of +2e. The four particles emitted in alpha decay include two protons and two neutrons, which makes the particle equal to a helium-4 ion. When an alpha particle is emitted from a nucleus, the parent nucleus loses two protons and two neutrons, which causes it to decrease by four atomic mass units (AMU).Polonium-210 emits an alpha particle during radioactive decay, according to the nuclear equation. The value of A for the parent polonium nucleus is 210, whereas the value of Z for the lead nucleus is 84. Therefore, the value of Z for polonium is 84 + 2 = 86, and the value of A is 210 + 4 = 214. After an alpha particle is emitted from the polonium nucleus, it is converted to a lead nucleus with a lower atomic number and a smaller mass. As a result, in the decay process, the parent nucleus becomes a new nucleus with a different atomic number and mass number. This explains why the value of Z for polonium is higher than the value of Z for lead

The value of A is 210, and the value of Z is 84. The given nuclear equation represents the decay of a polonium nucleus to form a lead nucleus, emitting an alpha particle.

Answer:

\(p[H+] = 10.042\)

Explanation:

As we know that

\(pKw = pH + pOH\)......eq (1)

we will calculate the pH of OH- and then we will calculate the pH of H+

So p[OH-] \(= - log [1.10 * 10^{-4}]\)

Solving the right side of the equation, we get

p[OH-]

\(= - [-3.958]\\= 3.958\)

Now we know that

\(pKw = 14.0\)

Substituting the value of pOH in the above equation, we get -

\(14.0 = p[H+] + 3.958\\p[H+] = 14 - 3.958\\p[H+] = 10.042\)

During hyperventilation, the pH of the blood increases (becomes more alkaline), while the carbon dioxide (CO2) level decreases. These changes are consistent with the prediction.

Hyperventilation refers to an increased rate and depth of breathing, leading to the removal of excess carbon dioxide from the body. As a result, the concentration of carbon dioxide in the blood decreases. Carbon dioxide reacts with water to form carbonic acid (H2CO3), which dissociates into bicarbonate ions (HCO3-) and hydrogen ions (H+). By reducing the carbon dioxide level, there is less production of H+ ions, resulting in an increase in blood pH, making it more alkaline.

The observed changes in pH and carbon dioxide levels during hyperventilation are consistent with the predicted response. Increased ventilation causes more carbon dioxide to be expelled from the body, shifting the equilibrium of the carbonic acid-bicarbonate buffer system. As a consequence, the pH of the blood rises, leading to alkalosis. These changes can be confirmed through blood gas analysis or other diagnostic tests.

the Clausius equation relates the change in entropy of a system to the heat flow and temperature at which the heat is transferred. This physical relationship reflects the fundamental principle that the entropy of a system tends to increase over time, and that heat flows spontaneously from hotter to cooler objects in order to achieve this increase in entropy.

The Clausius equation relates the change in entropy of a system to the heat flow and temperature at which the heat is transferred. It is given by:

ΔS = Qrev/T

where ΔS is the change in entropy of the system, Qrev is the amount of heat transferred reversibly between the system and its surroundings, and T is the temperature at which the heat is transferred.

To understand the physical basis of this equation, we need to consider the concept of entropy. Entropy is a measure of the disorder or randomness in a system. As a system evolves, it tends to move towards a state of maximum entropy, where its energy is spread out uniformly and there is no gradient or potential for further energy transfer. The second law of thermodynamics states that the entropy of an isolated system always increases over time, which implies that heat always flows spontaneously from hotter to cooler objects.

The Clausius equation relates this concept of entropy to the transfer of heat between a system and its surroundings. It tells us that the change in entropy of a system is proportional to the amount of heat transferred reversibly between the system and its surroundings, and inversely proportional to the temperature at which the heat is transferred. The term "reversible" refers to a process that can be reversed with infinitesimal changes to external conditions, so that the system and its surroundings return to their original states.

The physical relationship between the quantities in the Clausius equation can be understood as follows. The change in entropy of a system is related to the amount of heat transferred reversibly between the system and its surroundings, because heat flow is a key factor in determining the degree of disorder or randomness in a system. As heat flows from a hotter object to a cooler object, it tends to spread out and become more evenly distributed, which increases the entropy of the system. The temperature at which the heat is transferred is also important, because the higher the temperature, the greater the potential for heat to flow and increase the entropy of the system.

In summary, the Clausius equation relates the change in entropy of a system to the heat flow and temperature at which the heat is transferred. This physical relationship reflects the fundamental principle that the entropy of a system tends to increase over time, and that heat flows spontaneously from hotter to cooler objects in order to achieve this increase in entropy.

Answer:

Reduction

Explanation:

when an atom or ion decreases in oxidation state

The process in which an atom or ion experiences a decrease in its oxidation state is called reduction.

Reduction is the opposite of oxidation, which is the process in which an atom or ion experiences an increase in its oxidation state. In a redox (reduction-oxidation) reaction, one species undergoes reduction while the other undergoes oxidation.

In the process of reduction, the species gains electrons, resulting in a decrease in its oxidation state. The reducing agent is the species that donates electrons, while the oxidizing agent is the species that accepts electrons.

Reduction reactions are important in many chemical and biological processes, including metabolism, photosynthesis, and corrosion. The study of redox reactions is important in understanding the behavior of chemicals in natural and industrial processes.
