Which gas does not bind to the porphyrin ring Fe(II) ion in myoglobin? A) NO B) CO C) CO2 D) O2 E) H2S
Answers
The gas that does not bind to the porphyrin ring Fe (II) ion in myoglobin is option E) H2S. Myoglobin is a protein that is found in muscles and plays a crucial role in storing and transporting oxygen.
The heme group present in myoglobin contains an iron ion that is surrounded by a porphyrin ring. This iron ion is responsible for binding to oxygen and facilitating its transport. However, some gases like CO, NO, and O2 can also bind to this iron ion, which can have adverse effects on the body. Carbon monoxide CO and nitric oxide NO have a higher affinity for binding to the iron ion than oxygen, which can lead to oxygen deprivation in the body. In contrast, carbon dioxide CO2 can bind to a different site on the protein and assist in the release of oxygen. However, hydrogen sulfide H2S does not bind to the porphyrin ring Fe (II) ion in myoglobin and therefore does not interfere with oxygen transport.

B) Cr3+ is larger than Cr and Se is larger than Se2-.
C) Cr is larger than Cr3+ and Se2- is larger than Se.
D) Cr is larger than Cr3+ and Se is larger than Se2-.
Answers
The correct answer is D) Cr is larger than Cr3+ and Se is larger than Se2-.
When an atom gains or loses electrons, its size changes. When an atom gains electrons, it becomes larger because the additional electrons repel each other and push the electron cloud outward. When an atom loses electrons, it becomes smaller because there are fewer electrons to repel each other and the electron cloud contracts.
In the case of Cr3+, the atom has lost three electrons, making it smaller than the neutral Cr atom. In the case of Se2-, the atom has gained two electrons, making it larger than the neutral Se atom. Therefore, the correct answer is D) Cr is larger than Cr3+ and Se is larger than Se2-.

the balanced reaction between aqueous potassium hydroxide and aqueous acetic acid is __________.
Answers
Answer:
The balanced reaction between aqueous potassium hydroxide (KOH) and aqueous acetic acid (CH3COOH) is a neutralization reaction, which is a type of double displacement or metathesis reaction. In this reaction, an acid reacts with a base to produce water and a salt. The general form of a neutralization reaction is:
Acid + Base → Salt + Water
In the case of the reaction between potassium hydroxide and acetic acid, the products are water (H2O) and potassium acetate (KC2H3O2). The balanced chemical equation for this reaction is:
CH3COOH(aq) + KOH(aq) → KC2H3O2(aq) + H2O(l)
This equation is balanced because there are equal numbers of each type of atom on both sides of the equation. On the left side (the reactants), there are 2 carbon atoms, 4 hydrogen atoms, 1 potassium atom, and 3 oxygen atoms. On the right side (the products), there are also 2 carbon atoms, 4 hydrogen atoms, 1 potassium atom, and 3 oxygen atoms.

Answers
The equation that represents the amount of carbon dioxide (CO\(_{2}\) ) in parts per million (ppm) as a function of time (t) years after 1988 is "CO\(_{2}\) (ppm) = a * t + b".
In this equation, "a" represents the rate of increase of CO\(_{2}\) concentration in ppm per year, and "b" represents the initial CO\(_{2}\) concentration in ppm in the year 1988. The specific values of "a" and "b" would depend on the actual data and trends observed for CO\(_{2}\) concentrations over time.
This equation allows for the estimation of CO\(_{2}\) concentrations in ppm for different years after 1988, by multiplying the number of years by the rate of increase and adding the initial concentration. However, it is important to note that this is a simplified representation and actual CO\(_{2}\) concentration measurements may involve more complex factors and variations.

Answers
Answer: Based on Rock Formation, the student's judgment that Rock 2 is more likely to contain a fossil than Rock 1 is appropriate.
Explanation:
Rocks are classified into three types:
Igneous rocks, metamorphic rocks, and sedimentary rocks.
Rock 1 is an Igneous Rock.
When a fiery, molten rock crystallizes and hardens, it forms igneous rocks (from the Latin root word fire).
Rock 2 is a Sedimentary Rock
At standard surface temperatures, sedimentary rock is developed at or near the Earth's surface by the build-up and lithification of sediment (detrital rock) or by precipitation from suspension (chemical rock).
Under low temperatures and pressure, rock deposits produce sedimentary rocks in the ocean and on the Earth's crust. Plants and animals die and are deposited in a sedimentary deposit.
The following are the reasons why sedimentary rocks are the only rock types that hold fossils:
The burial of deceased plants and animals by additional sediment results in the build-up of minerals from water in bones, which leads to the development of fossils.
As a result, sedimentary rocks are the only rock types that retain fossils.

If you have 85.0 grams of CO₂, calculate how many moles of CO₂ would you have?
Answers
n=85/12(1)+16(2) =1.93 moles
Answer:
\(\boxed {\boxed {\sf 1.93 \ mol \ CO_2}}\)
Explanation:
We are asked to find how many moles of carbon dioxide are in 85.0 grams.
Grams are converted to moles using the molar mass (the mass of 1 mole of a substance). These values are found on the Periodic Table. They are equal to the atomic mass, but the units are grams per mole instead of atomic mass units.
Look up the molar masses of carbon and oxygen.
C: 12.011 g/mol O: 15.999 g/molThe formula CO₂ has a subscript of 2. There are 2 moles of oxygen in 1 mole of carbon dioxide. Multiply oxygen's molar mass by 2.
O₂: 15.999 g/mol * 2 =31.998 g/mol CO₂= 12.011 + 31.998=44.009 g/molSet up a conversion factor using the molar mass.
\(\frac {44.009 \ g \ CO_2}{ 1 \ mol \ CO_2}\)
We are converting 85.0 grams of carbon dioxide to moles, so we multiply by this value.
\(85.0 \ g \ CO_2 *\frac {44.009 \ g \ CO_2}{ 1 \ mol \ CO_2}\)
Flip the fraction so the units of grams of carbon dioxide cancel.
\(85.0 \ g \ CO_2 *\frac { 1 \ mol \ CO_2}{44.009 \ g \ CO_2}\)
\(85.0 *\frac { 1 \ mol \ CO_2}{44.009}\)
\(\frac {85.0}{44.009} \ mol \ CO_2\)
\(1.931423118 \ mol \ CO_2\)
The original measurement of grams (85.0) has 3 significant figures, so our answer must have the same. For the number we found, that is the hundredth place. The 1 in the thousandth place tells us to leave the 3.
\(1.93 \ mol \ CO_2\)
There are approximately 1.93 moles of carbon dioxide in 85.0 grams.
Select the compound with the greatest surface tension in the liquid phase.a. NBr3b. NF3c. NCl3
Answers
NCl₃ has the greatest surface tension in the liquid phase. Option c is correct answer.
The compound with the greatest surface tension in the liquid phase is the one that has the strongest intermolecular forces of attraction.
Among the given options, NBr₃ and NCl₃ are both polar molecules with a trigonal pyramidal molecular geometry. The N-F bond in NF₃ is more polar than the N-Br and N-Cl bonds, but the molecule has a trigonal pyramidal molecular geometry.
Therefore, NCl₃ has the strongest intermolecular forces of attraction, and thus the greatest surface tension in the liquid phase, due to the greater size of the chlorine atom compared to the bromine and nitrogen atoms, which results in a larger surface area and stronger intermolecular forces of attraction.

Answers
a) Km cannot be determined with the given data.
b) Vmax is 1.69 μmol dm-3 s-1.
c) Turnover number cannot be determined.
d) Catalytic efficiency cannot be calculated without Km.
a) How to determine the Michaelis constant?To determine the Michaelis constant (Km), maximum velocity (Vmax), turnover number, and catalytic efficiency of the enzyme based on the given data, we can use the Michaelis-Menten equation:
v = (Vmax * [ATP]) / (Km + [ATP])
where:
v is the velocity of the reaction in μmol dm-3 s-1.[ATP] is the concentration of ATP in μmol dm-3.Vmax is the maximum velocity of the reaction in μmol dm-3 s-1.Km is the Michaelis constant in μmol dm-3.Let's calculate each value:
Determine the Michaelis constant (Km):
We can use any of the given data points to calculate Km. Let's use the first data point, where [ATP] = 0.60 μmol dm-3 and v = 0.81 μmol dm-3 s-1:
0.81 = (Vmax * 0.60) / (Km + 0.60)
To solve for Km, we rearrange the equation:
Km + 0.60 = (Vmax * 0.60) / 0.81
Km + 0.60 = 0.741 * Vmax
Km = (0.741 * Vmax) - 0.60
b) How to determine the maximum velocity?Determine the maximum velocity of the reaction (Vmax):
We can use the highest data point to determine Vmax. From the given data, we can see that when [ATP] = 3.0 μmol dm-3, v = 1.69 μmol dm-3 s-1. Therefore, Vmax = 1.69 μmol dm-3 s-1.
c) How to calculate the turnover number?Determine the turnover number:
The turnover number represents the maximum number of substrate molecules converted to product per unit of time by a single enzyme molecule.
It is calculated as Vmax divided by the enzyme concentration. However, the enzyme concentration is not provided in the given data. Therefore, we cannot determine the turnover number with the given information.
d) How to calculate the catalytic efficiency?Calculate the catalytic efficiency of the enzyme:
Catalytic efficiency is a measure of how effectively an enzyme converts substrate to product. It is calculated as the ratio of Vmax to Km.
Catalytic efficiency = Vmax / Km
Now that we have determined Vmax and calculated Km, we can calculate the catalytic efficiency.

Answers
The empirical formula for limonene is C5H8, which represents the simplest whole-number ratio of carbon to hydrogen atoms in the compound. This information can be useful in determining the properties and behavior of limonene in various chemical reactions and applications.
Limonene is a hydrocarbon compound found in the essential oils of citrus fruits. It is a common ingredient in many household and personal care products, and is often used as a flavoring agent in food and beverages. The empirical formula for limonene is a representation of its molecular composition in terms of its simplest whole-number ratio of atoms.
To determine the empirical formula for limonene, we first need to know its molecular formula. The molecular formula for limonene is C10H16, meaning it contains 10 carbon atoms and 16 hydrogen atoms.
The next step is to find the simplest whole-number ratio of carbon to hydrogen atoms in the compound. This can be done by dividing both the carbon and hydrogen atoms by their greatest common factor, which is 2 in this case. Dividing by 2 gives us a ratio of C5H8, which is the empirical formula for limonene.
The empirical formula for limonene, C5H8, tells us the simplest whole-number ratio of carbon to hydrogen atoms in the compound, but it does not provide any information about the arrangement of atoms in the molecule.

a naoh solution is standardized using the monoprotic primary standard potassium hydrogen phthalate, khp (fm 204.22). if 0.698 6 g of khp requires 43.92 ml of naoh, what is the naoh concentration?
Answers
the NaOH concentration is 0.07799 M.
we need to find out the NaOH concentration. For this, we'll use the formula for molarity of a solution. Molarity is defined as moles of solute per litre of solution. The formula for Molarity is:
Molarity (M) = Mass of solute in grams / Molar mass of solute × Volume of solution in liters.
So, we can rearrange the formula as:
M = (m/V) × (1/MW)
where M is the molarity of solution, m is the mass of solute, V is the volume of solution and MW is the molecular weight of the solute. Using this formula, we can calculate the NaOH concentration as follows:
Given, mass of KHP = 0.6986 g
Volume of NaOH = 43.92 mL = 0.04392 L
To find: NaOH concentration
Using the given mass of KHP, we can find the number of moles of KHP as:
moles of KHP = mass / molar mass of KHP= 0.6986 / 204.22= 0.003421 mol
Now, using the balanced chemical equation between NaOH and KHP, we can say that: 1 mole of NaOH reacts with 1 mole of KHP.
This means that the number of moles of NaOH used in the reaction = 0.003421 mol
So, using the formula for molarity, we can say that:
Molarity of NaOH = moles of NaOH / volume of NaOH= 0.003421 / 0.04392= 0.07799 M
Therefore, the NaOH concentration is 0.07799 M.
