Which of the following is most critical for maintaining the native tertiary structure of a globular protein? Hydrogen bonds between regions of the polypeptide chain in the folded protein The hydrophobic effect of burying non-polar residues in the protein interior. Disulfide bonds between Cys residues in the protein. Salt bridges (i.e. ionic bonds between opposite charged side chains). None of these choices.
Answers
Among the given options, hydrogen bonds between regions of the polypeptide chain are the most critical for maintaining the native tertiary structure of a globular protein. They provide specific and directional interactions, contributing significantly to the stability of the folded protein.
The most critical factor for maintaining the native tertiary structure of a globular protein is the hydrogen bonds between regions of the polypeptide chain in the folded protein. Here's why:
1. Hydrogen bonds are formed between the electronegative atoms, typically oxygen or nitrogen, and hydrogen atoms in the protein. They contribute to the stabilization of the folded structure by providing specific and directional interactions between different regions of the polypeptide chain.
2. The hydrophobic effect, which involves the burying of non-polar residues in the protein interior, is important for stabilizing the protein's overall structure, but it does not directly contribute to maintaining the native tertiary structure.
3. Disulfide bonds between cysteine (Cys) residues can form covalent bonds and play a critical role in stabilizing the tertiary structure of some proteins, especially those found in extracellular environments. However, not all proteins have disulfide bonds, and the absence of disulfide bonds does not necessarily lead to loss of the native tertiary structure.
4. Salt bridges, also known as ionic bonds, occur between oppositely charged side chains and contribute to the stabilization of protein structure. While they can play a role in maintaining the structure, they are generally less critical compared to hydrogen bonds.

Determina el grado de pureza de un marmol (CaCO3), si al descomponerse 125 g del mismo se desprenden 20 litros de dióxido de carbono medidos a 15ºC y 1 atm.
Answers
Answer:
67.8%
Explanation:
La reacción de descomposición del CaCO₃ es:
CaCO₃ → CO₂ + CaO
Donde 1 mol de CaCO₃ al descomponerse produce 1 mol de CO₂ y 1 mol de CaO.
Usando la ley general de los gases, las moles de dioxido de carbono son:
PV = nRT.
Donde P es presión (1atm), V es volumen (20L), n son moles de gas, R es la constante de los gases (0.082atmL/molK) y T es temperatura absoluta (15 + 273.15 = 288.15K). Reemplazando los valores en la ecuación:
PV / RT = n
1atmₓ20L / 0.082atmL/molKₓ288.15K = 0.846 moles
Como 1 mol de CO₂ es producido desde 1 mol de CaCO₃, las moles iniciales de CaCO₃ son 0.846moles.
La masa molar de CaCO₃ es 100.087g/mol. Así, la masa de 0.846moles de CaCO₃ es:
0.846moles ₓ (100.087g / mol) = 84.7g de CaCO₃

cobalt (ii) hydroxide, co(oh)2(s), is dissolved in water forming a saturated solution having ph 9.79. calculate ksp for co(oh)2.
Answers
Cobalt (ii) hydroxide, co(oh)2(s), is dissolved in water forming a saturated solution having ph 9.79. ksp for co(oh)2 is 1.44 × 10^-15.
Cobalt (II) hydroxide, Co(OH)2(s), is dissolved in water forming a saturated solution having a pH of 9.79.
The solubility product constant (Ksp) for cobalt (II) hydroxide (Co(OH)2) is calculated below.
Cobalt(II) hydroxide Co(OH)2(aq) = Co2+ + 2OH-Ksp
= [Co2+][OH-]^2
If the pH is 9.79, the pOH is given as:
pOH = 14 - pH
= 14 - 9.79
= 4.21
From the equation, we know that:
[OH-]^2 = Ksp / [Co2+]
= 4.41 * 10^ -16/ [Co2+]
Take the square root of both sides to obtain:
[OH-] = (Ksp / [Co2+])^(1/2)
= (4.41 × 10^-16 / [Co2+])^(1/2)
Next, substitute the value of pOH to get:
[OH-] = 10 ^ -pOH
= 10^-4.21
Substitute the above value of [OH-] into the equation to obtain:
10^-4.21 = (4.41 × 10^-16 / [Co2+])^(1/2)[Co2+]
= (4.41 × 10^-16 / 10^-8.42)^2
= 0.122 mol/L
Thus, the solubility product constant (Ksp) for Co(OH)2 is 1.44 × 10^-15.
Cobalt (II) hydroxide, Co(OH)2(s), is dissolved in water forming a saturated solution having a pH of 9.79.
The solubility product constant (Ksp) for Co(OH)2 is 1.44 × 10^-15.

∆h° = -58.02 kj/mol and ∆s° = -176.6 j/mol･k. what is ∆g for the reaction at 50.0°c when p_no₂ = p_n₂o₄ = 0.200 atm? assume ∆h° and ∆s° are temperature independent.
Answers
At 50.0°C and with p_no₂ = p_n₂o₄ = 0.200 atm, the ∆g for the reaction is -0.753 kJ/mol.
To find ∆g for the reaction at 50.0°C, we need to use the Gibbs free energy equation, ∆g = ∆h - T∆s, where ∆h is the enthalpy change, ∆s is the entropy change, T is the temperature in Kelvin, and ∆g is the change in free energy.
First, we need to convert the temperature to Kelvin: 50.0°C + 273.15 = 323.15 K.
Next, we need to convert ∆h from kJ/mol to J/mol: ∆h = -58,020 J/mol.
Now we can calculate ∆g using the equation:
∆g = ∆h - T∆s
∆g = -58,020 J/mol - (323.15 K)(-176.6 J/mol･K)
∆g = -58,020 J/mol + 57,267 J/mol
∆g = -753 J/mol
Finally, we need to convert ∆g from J/mol to kJ/mol: ∆g = -0.753 kJ/mol.
Therefore, at 50.0°C and with p_no₂ = p_n₂o₄ = 0.200 atm, the ∆g for the reaction is -0.753 kJ/mol.

Answers
76.664 grams of mass presented in the 0.370 moles of Pb (1 mol of Pb has a mass of 207.2g.)
To determine the mass of 0.370 moles of Pb, you can use the given information that 1 mole of Pb has a mass of 207.2 grams. To find the mass of 0.370 moles of Pb, simply multiply the number of moles (0.370) by the mass of 1 mole of Pb (207.2 grams):
Using the rule of three, it is possible to solve proportionality issues between three known values and a fourth that is unknown.
The direct rule of three must be used if there is a direct relationship between the magnitudes, meaning that when one increases, the other does as well (or vice versa when one lowers).
The following formula, where a, b, and c are known values and x is the unknown value to calculate, must be used to solve a direct rule of three:
Mass = (Number of moles) × (Mass of 1 mole)
Mass = 0.370 moles × 207.2 g/mol

how molecular structure affects solubility?

Answer:
The molecular structure affects solubility mainly biased on its polarity or bonded ions.
Explanation:
Polar molecules will better interact with the water molecules and will dissolve easier. Nonpolar molecules can dissolve if they are small enough, however they don't interact well with the polar molecules. Bonded ions, such as NaCl split into a cation Na and an anion Cl which the positive charge on the Na will be attracted to the oxygen, and the negatively charged Cl will be attracted to the positive Hydrogen.
**Remember this rule, like dissolves like, meaning nonpolar dissolves nonpolar and polar dissolves polar.

b) If a mole of sugar costs 90 cents, what is the value of the sugar in a can of pop (3 marks)?
c) How many particles of sugar are there in the pop (3 marks)?
Answers
The number of sugar particles is 7.4 * 10^22 particles.
What is the mole?The mole is used to describe the amount of substance. The idea was first introduced by Professor Avogadro and the number of particles that constitute one mole of a substance was said to be 6.02 * 10^23 particles in a mole.
Thus;
Molar mass of sugar = 342 g/mol
Number of moles of sugar = 42 grams/342 g/mol = 0.123 moles
Now;
If 1 mole of sugar costs 90 cents
0.123 moles of sugar costs 0.123 moles * 90 cents/1 mole
= 11 cents
Now we know that;
1 mole of sugar contains 6.02 * 10^23 particles
0.123 moles of sugar contains 0.123 moles * 6.02 * 10^23 particles / 1 mole

Calculate the mass of sulfuric acid produced if 1.25 g of sulfur is reacted as indicated in the above equations.
Answers
The mass of sulfuric acid produced is 2.77 g.
To calculate the mass of sulfuric acid produced, we need to use stoichiometry. Here are the step-by-step calculations:
2S(s) + 3O2(g) → 2SO3(g)
SO3(g) + H2O(l) → H2SO4(l)
Calculate the molar mass of sulfur;
S = 32.06 g/mol
Convert the given mass of sulfur to moles;
1.25 g / 32.06 g/mol = 0.039 moles S
Use the mole ratio from the balanced equation to find the moles of sulfur trioxide produced;
0.039 moles S x (2 moles SO3 / 2 moles S) = 0.039 moles SO3
Use the mole ratio from the balanced equation to find the moles of sulfuric acid produced;
0.039 moles SO3 x (1 mole H2SO4 / 1 mole SO3) = 0.039 moles H2SO4
Calculate the mass of sulfuric acid produced;
0.039 moles H2SO4 x 98.08 g/mol = 2.77 g H2SO4
