The conversion of 1,3-bisphosphoglycerate to 3-phosphoglycerate is a reversible reaction.

In a reversible reaction, the products can be converted back to the reactants under certain conditions. The direction of the reaction will depend on the concentration of the reactants and products, as well as the conditions of the reaction such as temperature and pH. In this case, 1,3-bisphosphoglycerate can be converted to 3-phosphoglycerate and vice versa, depending on the presence of specific enzymes and cellular conditions. A low G allows for the reversible transfer of inorganic phosphate from the carboxyl group on 1,3BPG to ADP to create ATP. One acyl phosphate bond is broken while a new one is formed, which is why this happens. Since a catalyst is needed, the reaction cannot occur naturally or spontaneously. The enzyme phosphoglycerate kinase fills this function.

The activation energy for the reaction is 80 (without units).

To determine the activation energy (Eₐ) for a reaction using the Arrhenius equation, we need to use the given values of the rate constants (k) at two different temperatures (T) and solve for Eₐ. The Arrhenius equation is given by:

k = A * e^(-Eₐ / (R * T))

where:

k is the rate constant

A is the pre-exponential factor

Eₐ is the activation energy

R is the gas constant (8.314 J/(mol*K))

T is the temperature in Kelvin

We have two sets of data:

For the first set of data:

k₁ = 1.89 × 10⁽⁻¹⁾ s⁽⁻¹⁾ at T₁ = 541 K

For the second set of data:

k₂ = 5.70 s⁽⁻¹⁾ at T₂ = 601 K

Taking the ratio of the two equations, we have:

k₁ / k₂ = (A * e^(-Eₐ / (R * T₁))) / (A * e^(-Eₐ / (R * T₂)))

The pre-exponential factor (A) cancels out:

k₁ / k₂ = e^((-Eₐ / (R * T₁)) + (Eₐ / (R * T₂)))

Taking the natural logarithm (ln) of both sides to solve for Eₐ:

ln(k₁ / k₂) = (-Eₐ / (R * T₁)) + (Eₐ / (R * T₂))

Rearranging the equation:

ln(k₁ / k₂) = (Eₐ / (R * T₂)) - (Eₐ/ (R * T₁))

Now, let's substitute the known values:

ln(1.89 × 10⁽⁻¹⁾ / 5.70) = (Eₐ / (8.314 * 601)) - (Eₐ/ (8.314 * 541))

Simplifying the equation:

ln(1.89 × 10⁽⁻¹⁾ / 5.70) = Eₐ * (1 / (8.314 * 601) - 1 / (8.314 * 541))

Now, we can solve for Eₐ:

Eₐ = ln(1.89 × 10⁽⁻¹⁾ / 5.70) / (1 / (8.314 * 601) - 1 / (8.314 * 541))

The activation energy Eₐ is approximately 80 kJ/mol.

The maximum mass of lead that can be obtained by the reaction of 57.33 g PbO and 33.80 g of PbS is 58.4 g.

To answer this question, we need to use the balanced chemical equation for the reaction between lead (II) oxide (PbO) and lead (II) sulfide (PbS):

PbO + PbS → 2Pb + SO\(^{2}\)

According to the equation, one mole of PbO reacts with one mole of PbS to produce two moles of lead (Pb) and one mole of sulfur dioxide (SO\(^{2}\)). We can use this information to calculate the theoretical yield of lead from the given amounts of PbO and PbS.

First, we need to convert the masses of PbO and PbS to moles. The molar mass of PbO is 223.20 g/mol, so 57.33 g PbO is equal to 0.257 mol. The molar mass of PbS is 239.27 g/mol, so 33.80 g PbS is equal to 0.141 mol.

Next, we need to determine which reactant is limiting, i.e. which one will be completely consumed in the reaction. We can do this by calculating the number of moles of each reactant needed to produce the same amount of product. Since the ratio of PbO to PbS in the balanced equation is 1:1, we can compare the number of moles of each:

- PbO: 0.257 mol × (1 mol Pb / 1 mol PbO) = 0.257 mol Pb
- PbS: 0.141 mol × (1 mol Pb / 1 mol PbS) = 0.141 mol Pb

Since PbS is the limiting reactant (i.e. there is less of it than PbO), we will use its moles to calculate the theoretical yield of lead.

According to the equation, 1 mole of PbS produces 2 moles of Pb, so:

0.141 mol PbS × (2 mol Pb / 1 mol PbS) = 0.282 mol Pb

Finally, we can convert the moles of Pb to grams using the molar mass of Pb, which is 207.2 g/mol:

0.282 mol Pb × (207.2 g Pb / 1 mol Pb) = 58.4 g Pb

Therefore, 58.4 g is the maximum mass of lead that can be obtained by the reaction of 57.33 g PbO and 33.80 g PbS.

Option b-A The isotope ⁷₂H (7He) is more tightly bound than ⁵₂H (5He).

The stability of an isotope depends on its binding energy, which represents the amount of energy required to break apart the nucleus into its constituent particles. Higher binding energy indicates greater stability and tighter binding of nucleons within the nucleus.

To determine which isotope is more tightly bound, we compare their binding energies. The binding energy is related to the mass defect, which is the difference between the sum of the masses of the individual nucleons and the actual mass of the nucleus.

In this case, the atomic mass of ⁷₂H (7He) is 7.027991 u, and the atomic mass of ⁵₂H (5He) is 5.012057 u. The greater the mass defect, the more tightly bound the nucleus. Since the mass defect of ⁷₂H (7He) is greater than that of ⁵₂H (5He), it implies that ⁷₂H (7He) has a higher binding energy and is more tightly bound.

Atoms exchange or share electrons during bonding to obtain stability by completing their valence shells and also to achieve a lower energy state.

Atoms exchange or share electrons during bonding because of the force of attraction between two oppositely charged ions or particles called the electrostatic force. This force of attraction results in the formation of a bond, holding two atoms together within a compound.

The electrons are either shared or exchanged because they determine the chemical reactivity of an atom and are responsible for forming bonds between atoms. Atoms bond with each other to complete their outer shells and obtain stability, which is usually achieved by acquiring eight electrons in their valence shells. This is known as the octet rule.

The main types of chemical bonds that atoms form include covalent bonds and ionic bonds. Covalent bonds involve the sharing of electrons between atoms, while ionic bonds involve the transfer of electrons from one atom to another. Ionic bonding occurs between atoms that have a large difference in electronegativity, whereas covalent bonding occurs between atoms with a small difference in electronegativity.

In conclusion, atoms exchange or share electrons during bonding to obtain stability by completing their valence shells and also to achieve a lower energy state.

Two possible sources of systematic (determinate) error in the experiment are; Incorrect calibration of volumetric glasswareIncorrect mass of NaCl

To calculate the concentration of NaCl in the resulting solution in mg/L NaCl, we can use the formula; Concentration (mg/L) = (Mass of solute ÷ Volume of solution in L) × 1000 g / 1 mg NaCl is present in the stock solution of 25 mL. So, the mass of NaCl in the solution would be;0.0842 g ÷ 25 mL = 0.00337 g/mL. Now, in the resulting solution, a 1.00 mL aliquot of the stock solution is transferred to a 50.00 mL volumetric flask and diluted to volume. Therefore, the volume of the resulting solution is 50.00 mL. We will substitute these values in the formula, Concentration (mg/L) = (0.00337 g/mL ÷ 50 mL) × 1000 g / 1 mg concentration (mg/L) = 67.4 mg/L. Therefore, the concentration of NaCl in the resulting solution in mg/L NaCl is 67.4 mg/L.7.  Concentration = 67.4 mg/LTolerance = 4.28 mg/LTotal concentration = 67.4 + 4.28 mg/L = 71.68 mg/LWe round off this value to one decimal place; Total concentration = 71.7 mg/LTherefore, the concentration of NaCl in the resulting solution using propagation of error through the calculation is 67.4+0.4 mg/L.8.
