as a result of the sigmoidal shape of the o2-hb dissociation curve, there is very little change in hb saturation across a range of po2 values when po2 is high (e.g. between 80 and 100 mm hg in the text book figures). according to the reading, what is an advantage of the relatively flat shape of the curve here?

Answers

Answer 1

         Red blood cells contain hemoglobin. When carbonic acid, which is found in tissues, is present, hemoglobin releases the bound oxygen. The oxygen that is attached to hemoglobin is released into the blood's plasma and taken up by the tissues in the capillaries, which are also where carbon dioxide is created.

Throughout each of these deep breathing cycles, how do the partial pressures change?

          If more air is exchanged, the partial pressures of the outside atmosphere will approach but never reach them due to the remaining volume.

      Combustible Oxide : The dissociation curve shifts to the left as a result of one CO molecule binding to hemoglobin increasing the affinity of the other binding locations for oxygen.

       Lower CO2, greater pH, and lower temperature all move oxygen dissociation to the left.

       The pCO2 is significantly influenced by two variables. The person's breathing rate and depth are the first thing to consider. Someone who is hyperventilating will "blow out" more CO2, which will lower pCO2 levels. Holding one's breath causes CO2 to be retained, which raises pCO2 levels.

      Limited pressures : There are two reasons why the alveolar oxygen partial pressure is lower than the ambient O2 partial pressure. First, the upper airway humidifies the air as it reaches the lungs, lowering the partial pressure of oxygen to around 150 mmHg while increasing the partial pressure of water vapour (47 mmHg).

if there are 125 atoms of the parent isotope remaining and 875 atoms of the daughter isotope in a rock, how many half-lives have passed since the rock formed?

Answers

To solve this question we need to know the concept behind half life. Decay of radioactive element always comes under first order kinetics. Three half-lives have passed since the rock formed.

What is half life?

Half life tells about the time at which the radioactive material decays to half of its initial concentration.

Mathematically the the total number of half life can be calculated as

[tex]\rm \frac{t}{t_{1/2}} =-\frac{ln\frac{N_{t}}{N_{0}} }{ln 2}[/tex]

Nt= amount of the isotope that has not yet decayed after a time t

N₀= initial amount of the isotope

t=the time

[tex]t_{1/2}[/tex] = the half-life

Substituting the given values in the above equation

[tex]\rm \frac{t}{t_{1/2}} =-\frac{ln\frac{125}{100} }{ln 2}[/tex]

Solving this we get

3[tex]t_[1/2}[/tex]= t

Therefore, three half-lives have passed since the rock formed.

Suppose 200.0 g of ice absorb 1255.0 J of heat. What is the corresponding temperature change? Specific heat capacity of ice is 2.1 J/gC.

Answers

Considering the definition of calorimetry, if 200.0 g of ice absorb 1255.0 J of heat, the temperature change is 2.988°C.

Definition of calorimetry

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change). So, the amount of heat that a body receives or transmits is determined by the following expression:

Q = c×m×ΔT

Where:

Q is the heat exchanged by a body of mass m.c is a specific heat substance.ΔT is the temperature variation.

Temperature change in this case

In this case:

Q= 1255 Jc= 2.1 J/gCm= 200 gΔT= ?

Replacing in the definition of calorimetry:

1255 J = 2.1 J/gC× 200 g× ΔT

Solving:

1255 J ÷(2.1 J/gC× 200 g)= ΔT

2.988 °C= ΔT

How many grams of sodium fluoride are needed to prepare a 0.600m NaF solution that contains 600.0 g of water? Show your work.

Answers

Molality (W) is the ratio of the amount of substance of a solute (in moles – n) to the mass in kilograms of the solvent (m1). It can be calculated by the following formula:

W = n/m1

Step 1 - Let's discover how many moles of sodium fluoride is needed first.

Let's transform 600 g of water to kilograms:

1 g = 0.001 kg

600 g = 0.6 kg

W = 0.600m

m1 = 0.6

0.600 = n/0.6

n = 0.36 moles of sodium floride

Step 2 - Let's transform 0.36 moles of NaF into grams. Let's use the following formula: mass = moles x molar mass

molar mass of NaF = 42 g/mol

mass = 0.36 x 42

mass = 15.12 g

Answer: 15.12 g of NaF

liquid octane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . suppose 3.4 g of octane is mixed with 20.5 g of oxygen. calculate the minimum mass of octane that could be left over by the chemical reaction. be sure your answer has the correct number of significant digits.

Answers

The minimum mass of octane that could be left over is 0.468 grams.

Step 1: Data given

Mass of octane = 3.4 grams

Mass of oxygen = 20.5 grams

Molar mass octane = 114.23 g/mol

Molar mass oxygen = 32.0 g/mol

Step 2: The balanced equation

2C₈H₁₈ + 25O₂ → 16CO₂ + 18H₂O

Step 3: Calculate the number of moles

               

Moles = mass / molar mass

Moles octane = 3.4 grams / 114.23 g/mol

Moles octane = 0.0297 moles

Moles O₂ = 20.5 grams / 32.0 g/mol

Moles O₂ = 0.640 moles

Step 4: Calculate the limiting reactant

For 2 moles octane we need 25 moles O₂ to produce 16 moles CO₂ and 18 moles H₂O

O₂ is the limiting reactant. It will completely be consumed (0.640 moles). There will react 0.0320/ 12.5 = 0.0256 moles.

There will remain 0.0297 - 0.0256  = 0.0041 moles octane.

Step 5: Calculate mass octane remaining

Mass octane = moles * molar mass

Mass octane = 0.0041 moles * 114.23 g/mol

Mass octane = 0.468 grams

The minimum mass of octane that could be left over is 0.468 grams.

The percent composition of an unknown substance is 75.42 % Carbon, 6.63 % Hydrogen, 8.38 % Nitrogen, and 9.57 % Oxygen. If its molar mass is 334.0 g/mol what is its molecular formula?

Answers

The percent composition are the percent in mass of each atom in the molecule.

Since we know that the molar mass of the substance is 334.0 g/mol, we can use it to figure out how much of each atom we have per molecule.

Starting from carbon, we know it is 75.42% of the mass.

In 1 mol of the substance, there are 334.0 g, 75.42% of which is from carbon atoms.

So, in 1 mol of the substance, there are the following mass of carbon:

[tex]m_C=334.0g\cdot75.42\%=334.0g\cdot0.7542=251.9028g[/tex]

The aromic mass of the carbon atom is 12.0107 g/mol.

That is, in 1 mol of the substance -> 251.9028 g of C.

That mass of carbon is equivalent to:

[tex]\begin{gathered} M_C=\frac{m_C}{n_C} \\ n_C=\frac{m_C}{M_C}=\frac{251.9028g}{12.0107g/mol}=20.97\ldots mol\approx21mol \end{gathered}[/tex]

So, in 1 mol of the substance -> 251.9028 g of C -> 21 mol of C. This means that for each molecule of the substance we have 21 atoms of carbon.

Now, we can just repeat the process for Hydrogen, Nitrogen and Oxygen.

Hydrogen has an atomic mass of 1.00794 g/mol, and the percent composition of it is 6.63%, so:

[tex]m_H=334.0g\cdot0.0663=22.1442g[/tex][tex]n_H=\frac{m_H}{M_H}=\frac{22.1442g}{1.00794g/mol}=21.96\ldots mol\approx22mol[/tex]

So, for each molecule of the substance there are 22 atoms of hydrogen.

Nitrogen has an atomic mass of 14.0067 g/mol, and the percent composition of it is 8.38%, so:

[tex]m_N=334.0g\cdot0.0838=27.9892g[/tex][tex]n_N=\frac{m_N}{M_N}=\frac{27.9892g}{14.0069g/mol}=1.998\ldots mol\approx2mol[/tex]

So, for each molecule of the substance there are 2 atoms of nitrogen.

Oxygen has an atomic mass of 15.9994 g/mol, and the percent composition of it is 9.57%, so:

[tex]\begin{gathered} m_O=334.0g\cdot0.0957=31.9638g \\ n_O=\frac{m_O}{M_O}=\frac{31.9638g}{15.9994g/mol}=1.997\ldots mol\approx2mol \end{gathered}[/tex]

So, for each molecule of the substance there are 2 atoms of oxygen.

To summarize, we have, for each molecule of the substance:

- 21 carbon

- 22 hydrogen

- 2 nitrogen

- 2 oxygen

So, the molecular form of the substance is C₂₁H₂₂N₂O₂.

How do the presence or absence of partial charges at the molecular scale help explain a liquid’s ability to dissolve salts?.

Answers

The presence of partial charges in a liquid enables the liquid to split the bonds of the salt when dissolved in it. On the other hand, in the absence of partial charges, the liquid won't be able to break bonds apart and dissolve salts in it.

How a liquid dissolves things?

In a liquid such as water the charges are arranged in a such a way that generates partial positive and negative sides on hydrogen and oxygen atoms giving rise to polarity.

So when a substance such as salt is dissolved in water, the partial positive charge attracts the negative side of the salt with a definite force while partial negative charge of liquid pulls the positive charges apart.

In general, the partial charges of the liquid pull apart the charges of the added substance which results in breaking their chemical bonds and dissolving them.

(B) A person's weight on the moon is the more than on Earth, due to the force of gravity.

(C) A person's weight on the moon is the same as on Earth, due to the force of gravity.

(D) A person's mass on the moon is more than on Earth, due to the force of gravity.

Answers

Among the given options, the option A which is A person's weight on the moon is the less than on the Earth, due to the force of gravity, is true.

The weight of a person is usually one-sixth less than their Earth's weight. Only the value of weight fluctuates from Earth to the moon, whereas the mass stays the same on both earth and moon.

This happens due to the gravitational force of the moon. Moon is smaller than the Earth, therefore it has low gravitational forces. Moon's gravitational force leads to the difference in the weights on the Earth and the moon.

The moon of Earth has comparitively less amount of mass than Earth. It is not only small in size than but it also is not as dense as earth. It is only 60 % dense which leads to lower gravitational pull, hence leading to difference in the weight.

Two solutions are made by mixing sugar and enough water to make a 1 liter solution. One contains 10% sugar and the other 20% sugar. Which solution has more solvent?.

Answers

Two solutions are made by mixing sugar and enough water to make a 1 liter solution. 10% sugar has more solvent.

In chemistry, a solution is a homogeneous mixture of two or more compounds in their relative proportions that can be continually altered up to what is referred to as the limit of solubility. Although the word "solution" is frequently used to refer to the liquid state of matter, solutions of gases and solids are also possible. A solute is dissolved by a solvent (s), which is a substance (from the Latin solv, "loosen, untie, solve,") to produce a solution. The most common form of a solvent is a liquid, although other forms include solids, gases, and supercritical fluids. Depending on the temperature, a different amount of solute can dissolve in a given volume of solvent. Solvents are extensively utilized in paints, paint removers, inks, and dry cleaning.
