A camel hump contains 12 kg of triacyclglycerols,
a) Given that there are 0.491 moles of ATP per gram of fat, how many moles of ATP could be produced by the fat in the camel hump?
______moles
b) If the hydrolysis of ATP releases 7.3 kcal/mole, how many kilocalories are produced by the utilization of the fat?
______kcal
Answers
The answer is 5892 moles of ATP will be produced from 12 kg of triacyclglycerols, and 43012 kcal energy will be generated by the utilization of the fat .
What are Triacyclglycerols ?Triacylglycerols are formed by linking fatty acids with an ester linkage to three alcohol groups in glycerol.
Triacylglycerols are the form in which fat energy is stored in adipose tissue.
A camel hump contains 12kg = 12000 gm of Triacyclglycerols
a) It is given that there are 0.491 moles of ATP per gram of fat ,
So for 12000 gm of fat in camel hump 12000 * 0.491 moles of ATP will be produced .
= 5892 moles
Therefore Answer is 5892 moles .
If Hydrolysis of ATP releases 7.3 kcal/mole
so 5892 moles will produce 5892 * 7.3 kcal
=43012 kcal energy will be generated by the utilization of the fat.

What is the relationship between the enthalpy (AH) and entropy (AS) of a
reaction that is spontaneous at higher temperatures but not at lower
temperatures?
Answers
The relationship between the enthalpy (ΔH) and entropy (ΔS) of a
reaction that is spontaneous at higher temperatures but not at lower
temperatures is +ΔH, - Δs.
Relationship between enthalpy and entropy
The relationship between enthalpy (ΔH) and entropy (ΔS) is given by Gibs free energy.
ΔG = ΔH - TΔs
When ΔH < 0 and Δs < 0, ΔG = -ve (-ΔH, - Δs) (for lower temperature)
Also, when ΔH < 0 and Δs = +, ΔG = -ve (-ΔH, +Δs) (for all temperature)
When ΔH > 0 and Δs < 0, ΔG = -ve (+ΔH, - Δs) (for higher temperature)
Thus, the relationship between the enthalpy (ΔH) and entropy (ΔS) of a
reaction that is spontaneous at higher temperatures but not at lower
temperatures is +ΔH, - Δs.

Ksp = [CaF₂] / ([Ca²+] [F] ²)
Answers
The Ksp of the compound CaF2 is given as; Ksp = [Ca2+] [F]²
What is solubility product?The term solubility product has to do with the extent to which a substance dissolves in solution.
For the compound CaF2, we have; CaF2(s) ⇆Ca^2+(aq) + 2F^-(aq). Hence, the Ksp of the solution is Ksp = [Ca2+] [F]²

In an aqueous solution all ions are present. Some of these ions will react, however, some will not. The ions that do not
react in solution are called
a. Inert ions
B. Spectator ions
C. Cations
d. Anions
Answers
Answer:
B. Spectator ions
Explanation:
Spectator ions are described as spectators literally because they "spectate", or, in other words, do not participate in the overall reaction. They may show up in the reaction equation, but they don't react themselves.
Thus, spectator ions stay unchanged throughout a reaction. We see many spectator ions in precipitation reactions. Remember that ionic compounds disassociate in solution.
For example, the reaction between silver nitrate [tex]AgNO_{3}[/tex] and sodium chloride [tex]NaCl[/tex] produces a solid precipitate of silver chloride [tex]AgCl[/tex] as represented by the equation below:
[tex]Ag^+_{(aq)} + NO^-_{3(aq)}+Na^+_{(aq)}+Cl^-_{(aq)}[/tex] -------> [tex]AgCl_{(s)}+Na^+_{(aq)}+NO_{3(aq)}^-[/tex]
However, the sodium and nitrate ions remained aqueous, like before, so they did not react. Thus, they are spectator ions.
